Subject: [PATCH] Remove bundled, unmaintained libmng source code
[ChangeLog][Third-Party Code] The unmaintained bundled libmng has been
removed. Building the mng handler will require libmng to be present as
a system or external library.

-1.0.0 (Feb 6th 2001)
---------------------
-
-in short:
-
-First public release. Finally(!)
-
-This is the 0.9.5 CVS version, which will never be released, because I feel it
-is now ready for a public release. So apart from the version-numbers here and
-there, all other changes are listed under 0.9.5.
-
-This library will work with every MNG/JNG known and available to me. Note that
-there are still parts that need to be coded, and that MNG support is around
-90-95% (JNG at 100%). It is however compliant with the latest and greatest
-MNG 1.0 specification.
-
-I hope to dedicate a bit more time this year to finish up full support and fill
-in the remaining blanks. But this is coming out of my spare time. And extra
-help is always appreciated.
-
-Please enjoy!

-If you happen to find problems with autoconfiguration and building,

-
-**********************************************************************
-**********************************************************************

-
-
-Configuration from CVS
-======================
-
-If you're using source checked out from CVS, rather than a source
-distribution tarball, please be aware that you can use ./autogen.sh in
-place of ./configure below.
-
-Because this is a cross-platform project, the source templates for
-the autoconf scripts are sequestered in the 'makefiles' directory.
-Running './autogen.sh' will copy them into their conventional places at
-the lop level. If you already see the files there, you don't need to
-worry about this step.
-
-Basic Installation
-==================
-
- These are generic installation instructions.
-
- The `configure' shell script attempts to guess correct values for
-various system-dependent variables used during compilation. It uses
-those values to create a `Makefile' in each directory of the package.
-It may also create one or more `.h' files containing system-dependent
-definitions. Finally, it creates a shell script `config.status' that
-you can run in the future to recreate the current configuration, a file
-`config.cache' that saves the results of its tests to speed up
-reconfiguring, and a file `config.log' containing compiler output
-(useful mainly for debugging `configure').
-
- If you need to do unusual things to compile the package, please try
-to figure out how `configure' could check whether to do them, and mail
-diffs or instructions to the address given in the `README' so they can
-be considered for the next release. If at some point `config.cache'
-contains results you don't want to keep, you may remove or edit it.
-
- The file `configure.in' is used to create `configure' by a program
-called `autoconf'. You only need `configure.in' if you want to change
-it or regenerate `configure' using a newer version of `autoconf'.
-
-The simplest way to compile this package is:
-
- 1. `cd' to the directory containing the package's source code and type
- `./configure' to configure the package for your system. If you're
- using `csh' on an old version of System V, you might need to type
- `sh ./configure' instead to prevent `csh' from trying to execute
- `configure' itself.
-
- Running `configure' takes awhile. While running, it prints some
- messages telling which features it is checking for.
-
- 2. Type `make' to compile the package.
-
- 3. Optionally, type `make check' to run any self-tests that come with
- the package.
-
- 4. Type `make install' to install the programs and any data files and
- documentation.
-
- 5. You can remove the program binaries and object files from the
- source code directory by typing `make clean'. To also remove the
- files that `configure' created (so you can compile the package for
- a different kind of computer), type `make distclean'. There is
- also a `make maintainer-clean' target, but that is intended mainly
- for the package's developers. If you use it, you may have to get
- all sorts of other programs in order to regenerate files that came
- with the distribution.
-
-Compilers and Options
-=====================
-
- Some systems require unusual options for compilation or linking that
-the `configure' script does not know about. You can give `configure'
-initial values for variables by setting them in the environment. Using
-a Bourne-compatible shell, you can do that on the command line like
-this:
- CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
-
-Or on systems that have the `env' program, you can do it like this:
- env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
-
-Compiling For Multiple Architectures
-====================================
-
- You can compile the package for more than one kind of computer at the
-same time, by placing the object files for each architecture in their
-own directory. To do this, you must use a version of `make' that
-supports the `VPATH' variable, such as GNU `make'. `cd' to the
-directory where you want the object files and executables to go and run
-the `configure' script. `configure' automatically checks for the
-source code in the directory that `configure' is in and in `..'.
-
- If you have to use a `make' that does not supports the `VPATH'
-variable, you have to compile the package for one architecture at a time
-in the source code directory. After you have installed the package for
-one architecture, use `make distclean' before reconfiguring for another
-architecture.
-
-Installation Names
-==================
-
- By default, `make install' will install the package's files in
-`/usr/local/bin', `/usr/local/man', etc. You can specify an
-installation prefix other than `/usr/local' by giving `configure' the
-option `--prefix=PATH'.
-
- You can specify separate installation prefixes for
-architecture-specific files and architecture-independent files. If you
-give `configure' the option `--exec-prefix=PATH', the package will use
-PATH as the prefix for installing programs and libraries.
-Documentation and other data files will still use the regular prefix.
-
- In addition, if you use an unusual directory layout you can give
-options like `--bindir=PATH' to specify different values for particular
-kinds of files. Run `configure --help' for a list of the directories
-you can set and what kinds of files go in them.
-
- If the package supports it, you can cause programs to be installed
-with an extra prefix or suffix on their names by giving `configure' the
-option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
-
-Optional Features
-=================
-
- Some packages pay attention to `--enable-FEATURE' options to
-`configure', where FEATURE indicates an optional part of the package.
-They may also pay attention to `--with-PACKAGE' options, where PACKAGE
-is something like `gnu-as' or `x' (for the X Window System). The
-`README' should mention any `--enable-' and `--with-' options that the
-package recognizes.
-
- For packages that use the X Window System, `configure' can usually
-find the X include and library files automatically, but if it doesn't,
-you can use the `configure' options `--x-includes=DIR' and
-`--x-libraries=DIR' to specify their locations.
-
-Specifying the System Type
-==========================
-
- There may be some features `configure' can not figure out
-automatically, but needs to determine by the type of host the package
-will run on. Usually `configure' can figure that out, but if it prints
-a message saying it can not guess the host type, give it the
-`--host=TYPE' option. TYPE can either be a short name for the system
-type, such as `sun4', or a canonical name with three fields:
- CPU-COMPANY-SYSTEM
-
-See the file `config.sub' for the possible values of each field. If
-`config.sub' isn't included in this package, then this package doesn't
-need to know the host type.
-
- If you are building compiler tools for cross-compiling, you can also
-use the `--target=TYPE' option to select the type of system they will
-produce code for and the `--build=TYPE' option to select the type of
-system on which you are compiling the package.
-
-Sharing Defaults
-================
-
- If you want to set default values for `configure' scripts to share,
-you can create a site shell script called `config.site' that gives
-default values for variables like `CC', `cache_file', and `prefix'.
-`configure' looks for `PREFIX/share/config.site' if it exists, then
-`PREFIX/etc/config.site' if it exists. Or, you can set the
-`CONFIG_SITE' environment variable to the location of the site script.
-A warning: not all `configure' scripts look for a site script.
-
-Operation Controls
-==================
-
- `configure' recognizes the following options to control how it
-operates.
-
-`--cache-file=FILE'
- Use and save the results of the tests in FILE instead of
- `./config.cache'. Set FILE to `/dev/null' to disable caching, for
- debugging `configure'.
-
-`--help'
- Print a summary of the options to `configure', and exit.
-
-`--quiet'
-`--silent'
-`-q'
- Do not print messages saying which checks are being made. To
- suppress all normal output, redirect it to `/dev/null' (any error
- messages will still be shown).
-
-`--srcdir=DIR'
- Look for the package's source code in directory DIR. Usually
- `configure' can determine that directory automatically.
-
-`--version'
- Print the version of Autoconf used to generate the `configure'
- script, and exit.
-
-`configure' also accepts some other, not widely useful, options.

-Configuration options in libmng
-===============================
-
-The library is fairly configurable through the use of a number of defines.
-Please note however that certain defines are for internal use only.
-The following list gives a summary of options that can be used externally to
-define the functionality of the library:
-
-========================================
-
-#define MNG_BUILD_DLL
-
-This is used to indicate that a "standard" DLL should result from compiling
-the library. Please note the remarks in README.dll if you intend to work
-with the library as a DLL. The purpose of this option is to ensure that
-DLL builds have the same set of functions.
-
-#define MNG_BUILD_SO
-
-This is used to indicate that a "standard" shared library (SO) should result
-from a compilation. The purpose of this option is to ensure that all
-shared libraries generated this way will have the same set of functions.
-
-#define MNG_USE_DLL / #define MNG_USE_SO
-
-These should be used when including the library header in the compilation
-of an application to indicate that the compiler/linker must take the
-necessary steps to make the binary executable to use the standard DLL
-or shared library (SO).
-
-#define MNG_SKIP_ZLIB / #define MNG_SKIP_LCMS / #define MNG_SKIP_IJG6B
-
-Use these in conjunction with MNG_USE_DLL / MNG_USE_SO. This is useful if
-you only need the external definitions of the MNG library and not the others,
-which will speed up the compilation process.
-
-#define MNG_SUPPORT_FULL / #define MNG_SUPPORT_LC / #define MNG_SUPPORT_VLC
-
-These can be used to indicate the level of MNG spec compliance required.
-Currently only full MNG compliance is supported.
-
-#define MNG_SUPPORT_IJG6B
-
-This can be used to indicate if JNG support is required. This option will
-include the IJG JPEG-library. Note that MNG_SUPPORT_FULL will automatically
-set this option. Use this only if you need JNG support with MNG-(V)LC.
-
-#define MNG_FULL_CMS / #define MNG_GAMMA_ONLY / #define MNG_NO_CMS /
-#define MNG_APP_CMS
-
-These indicate the color-correction support level of the library.
-If you are on a platform that supports lcms (Little CMS by Marti Maria Saguar)
-then it is highly recommended to define MNG_FULL_CMS.
-If your platform has it's own CMS then select MNG_APP_CMS and be sure to
-include the appropriate callbacks in your app.
-In all other cases it is recommended to define MNG_GAMMA_ONLY.
-
-#define MNG_SUPPORT_READ / #define MNG_SUPPORT_WRITE /
-#define MNG_SUPPORT_DISPLAY
-
-These indicate the high-level support for reading, writing and/or
-displaying files. Note that in order to display a file, you'll need to read
-it first. (yes, really!)
-
-#define MNG_STORE_CHUNKS
-
-This indicates that the library should store chunk-information when reading
-a file. This information can then be processed through the
-MNG_ITERATE_CHUNKS() function. Note that you must specify this option if
-you want to create and write a new file.
-
-#define MNG_ACCESS_CHUNKS
-
-This is used to indicate that the app may need access to internally stored
-chunk information. MNG_STORE_CHUNKS must be defined as well for this option
-to function properly.
-
-#define MNG_INTERNAL_MEMMNGMT
-
-You can use this to have the library handle it's own memory allocation and
-deallocation through the "standard" memory functions. This option is turned
-off by default, which means your app must define the memory callbacks.
-
-#define MNG_ERROR_TELLTALE
-
-Set this on to allow human-readable error-messages to be included in the
-library and the error function and callback.
-
-#define MNG_BIGENDIAN_SUPPORTED
-
-This option should be used to indicate the hardware is based on big endian
-integers.
-
-#define MNG_SUPPORT_TRACE / #define MNG_TRACE_TELLTALE
-
-These two can be used when debugging an app. You'll need to have the trace
-callback setup also. This allows for a rather thorough investigation of the
-libraries function paths.
-
-========================================
-
-Any other optional defines you may encounter are for internal use only.
-please do not specify them externally. In case of doubt, consult the
-support email lists. More info can be found on http://www.libmng.com

-Standard Windows DLL
-====================
-
-The DLL provided in the BCB/win32dll directory is meant as the sole candidate
-for distributions, based on libmng.dll, that install the DLL into the public
-Windows system-directory. The outline herein defines the requirements to
-which such a distribution must comply. If you cannot comply with these
-requirements please install the dll in the same directory as your application
-and NOT in the Windows system-directory!!!
-
-
-1) Only the DLL already assembled in the libmng distribution may be used for
- other distributions!
-
-2) Only stable public releases are eligible for distribution! A public release
- is one where the y-value of the x.y.z version-code is an even number.
- Eg. 1.0.0, 1.2.1, 2.4.7, etc.
-
-3) The installation program MUST store the DLL in the Windows system-directory!
- Eg. C:\WinNT\System32, C:\Windows98\System
- (Note: InstallShield users can use the <SYSDIR> variable)
-
-3) The installation program MUST flag the file as a shared library!
-
-4) The installation program MUST NOT install the DLL if a newer version
- already exists in the Windows system-directory! The standard DLL provided
- contains the Windows-default version-numbering system. PLEASE USE IT!!
- DO NOT rely on the date or size of the files.
-
-5) An uninstall procedure MAY NOT remove the DLL if other applications are
- still linked to it! Proper handling as a shared library is imperitive.
-
-6) TEST IT, TEST IT, TEST IT!!! (I just can't stress this enough)
- If you don't have enough time, let someone else test it BEFORE you
- distribute!
-
-
-The penalty for violating these rules is inclusion of your name in the list
-of endangered but useless species (just below the GIF entry!), and on my
-blacklist. YOU HAVE BEEN FOREWARNED!

------------------------------------------------------
-
-win32dll - sample project to create a Windows dll. Requires zlib1.2.1,
- IJG jpgsrc6b and lcms1.0.14. The directories containing these
- libraries must be at the same level as the libmng directory.
- So if you're in the directory with this file and the libmng

- respectively.
-
-!!! To run the other Win32 samples you need to copy the libmng.dll

-
-mngtree - sample project to create a little command-line tool that dumps
- the chunk-structure of a given file onto stdout.
-
-bogus - a completely bogus example on how to create a perfectly valid
- (though slightly biased) MNG.
-
-mngview - port of the Delphi mngview sample. contributed by Andy Protano.
- see also README.contrib
-
-mngrepair- an example on how to fix invalid MNG files
- uses the new mng_copy_chunks() function and MNG_SOFTERRORS to
- 'ignore' certain input-errors. This conditional *MUST* only be used
- for exactly this kind of software; eg. repair utilities.

-
-mngview - sample project for a simple mng-viewer. The general unit in

-Packaging Libmng for distribution
----------------------------------
-
-These are some notes for those building binaries for distribution.
-
-We're interested to hear about anywhere libmng is helpful, so let us
-know if you're including it with your application or OS. Also, if your
-build is publicly accessible, we'd be happy to link to it from
-the libmng site.
-
-However, We respectfully request that you *not* distribute binaries as a
-shared library (DLL) with any of the major features disabled. While
-there is support for this in terms of #ifdef directives (in
-libmng_conf.h) and autoconf switches they are intended for embedded
-application and testing. The default compilation options support the
-full MNG specification, and we wish to avoid the confusion among
-general users that partial support would engender.
-
-
-Platform specific notes:
-
-We have a basic .spec file for generating rpms. Send us a note if you'd
-like to clean it up.

-libmng - Multiple-image Network Graphics (MNG) Reference Library 1.0.9
-
-DESCRIPTION
-The libmng library supports decoding, displaying, encoding, and various
-other manipulations of the Multiple-image Network Graphics (MNG) format
-image files. It uses the zlib compression library, and optionally the
-JPEG library by the Independant JPEG Group (IJG) and/or
-lcms (little cms), a color-management library by Marti Maria Saguer.
-
-
-I. Introduction
-
-This file describes how to use and modify the MNG reference library
-(known as libmng) for your own use. There are seven sections to this
-file: introduction, callbacks, housekeeping, reading, displaying,
-writing, and modification and configuration notes for various special
-platforms. We assume that libmng is already installed; see the
-INSTALL.README file for instructions on how to install libmng.
-
-Libmng was written to support and promote the MNG specification.
-
-The latest MNG specification (currently 1.0) is available at
- http://www.libpng.org/pub/mng/
-
-Other information about MNG can be found at the MNG home page at
- http://www.libpng.org/pub/mng/
-
-The latest version of libmng can be found at its own homepage at
- http://www.libmng.com/
-
-In most cases the library will not need to be changed.
-For standardization purposes the library contains both a Windows DLL
-and a makefile for building a shared library (SO). The library is
-written in C, but an interface for Borland Delphi is also available.
-
-Libmng has been designed to handle multiple sessions at one time,
-to be easily modifiable, to be portable to the vast majority of
-machines (ANSI, K&R, 32-, and 64-bit) available, and to be easy
-to use.
-
-Libmng uses zlib for its compression and decompression of MNG files.
-Further information about zlib, and the latest version of zlib, can be
-found at the zlib home page, <http://www.zlib.org/>.
-The zlib compression utility is a general purpose utility that is
-useful for more than MNG/PNG files, and can be used without libmng.
-See the documentation delivered with zlib for more details.
-
-Libmng optionally uses the JPEG library by the Independant JPEG Group
-(IJG). This library is used for the JNG sub-format, which is part of
-the MNG specification, and allows for inclusion of JPEG decoded and
-thus highly compressed (photographic) images.
-Further information about the IJG JPEG library and the latest sources
-can be found at <http://www.ijg.org/>.
-
-Libmng can also optionally use the lcms (little CMS) library by
-Marti Maria Saguer. This library provides an excellent color-management
-system (CMS), which gives libmng the ability to provide full
-color-correction for images with the proper color-information encoded.
-Further information and the latest sources can be found at
-<http://www.littlecms.com/>.
-
-Libmng is thread safe, provided the threads are using different
-handles as returned by the initialization call.
-Each thread should have its own handle and thus its own image.
-Libmng does not protect itself against two threads using the
-same instance of a handle.
-
-The libmng.h header file is the single reference needed for programming
-with libmng:
-
-#include <libmng.h>
-
-
-II. Callbacks
-
-Libmng makes extensive use of callback functions. This is meant to
-keep the library as platform-independant and flexible as possible.
-Actually, the first call you will make to the library, already contains
-three parameters you can use to provide callback entry-points.
-
-Most functions must return a mng_bool (boolean). Returning MNG_FALSE
-indicates the library the callback failed in some way and the library
-will immediately return from whatever it was doing back to the
-application. Returning MNG_TRUE indicates there were no problems and
-processing can continue.
-
-Let's step through each of the possible callbacks. The sections on
-reading, displaying and writing will also explain which callbacks are
-needed when and where.
-
-- mng_ptr mng_memalloc (mng_size_t iLen)
-
-A very basic function which the library uses to allocate a memory-block
-with the given size. A typical implementation would be:
-
- mng_ptr my_alloc (mng_size_t iLen) {
- return calloc (1, iSize);
- }
-
-Note that the library requires you to zero-out the memory-block!!!
-
-- void mng_memfree (mng_ptr pPtr,
- mng_size_t iLen)
-
-Counterpart of the previous function. Typically:
-
- void my_free (mng_ptr pPtr, mng_size_t iLen) {
- free (pPtr);
- }
-
-- mng_bool mng_openstream (mng_handle hHandle)
-- mng_bool mng_closestream (mng_handle hHandle)
-
-These are called by the library just before it starts to process
-(either read or write) a file and just after the processing stops.
-This is the recommended place to do I/O initialization & finalization.
-Whether you do or not, is up to you. The library does not put any
-meaning into the calls. They are simply provided for your convenience.
-
-- mng_bool mng_readdata (mng_handle hHandle,
- mng_ptr pBuf,
- mng_uint32 iBuflen,
- mng_uint32p pRead)
-
-This function is called when the library needs some more input while
-reading an image. The reading process supports two modes:
-Suspension-mode (SMOD) and non-suspension-mode (NSMOD).
-See mng_set_suspensionmode() for a more detailed description.
-
-In NSMOD, the library requires you to return exactly the amount of bytes
-requested (= iBuflen). Any lesser amount indicates the input file
-is exhausted and the library will return a MNG_UNEXPECTEDEOF errorcode.
-
-In SMOD, you may return a smaller amount of bytes than requested.
-This tells the library it should temporarily wait for more input to
-arrive. The lib will return with MNG_NEEDMOREDATA, and will expect a
-call to mng_read_resume() or mng_display_resume() next, as soon as
-more input-data has arrived.
-
-For NSMOD this function could be as simple as:
-
- mng_bool my_read (mng_handle hHandle,
- mng_ptr pBuf,
- mng_uint32 iBuflen,
- mng_uint32p pRead) {
- *pRead = fread (pBuf, 1, iBuflen, myfile);
- return MNG_TRUE;
- }
-
-- mng_bool mng_writedata (mng_handle hHandle,
- mng_ptr pBuf,
- mng_uint32 iBuflen,
- mng_uint32p pWritten)
-
-This function is called during the mng_write() function to actually
-output data to the file. There is no suspension-mode during write,
-so the application must return the exact number of bytes the library
-requests to be written.
-
-A typical implementation could be:
-
- mng_bool my_write (mng_handle hHandle,
- mng_ptr pBuf,
- mng_uint32 iBuflen,
- mng_uint32p pWritten) {
- *pWritten = fwrite (pBuf, 1, iBuflen, myfile);
- return MNG_TRUE;
- }
-
-- mng_bool mng_errorproc (mng_handle hHandle,
- mng_int32 iErrorcode,
- mng_int8 iSeverity,
- mng_chunkid iChunkname,
- mng_uint32 iChunkseq,
- mng_int32 iExtra1,
- mng_int32 iExtra2,
- mng_pchar zErrortext)
-
-This function is called whenever an error is detected inside the
-library. This may be caused by invalid input, callbacks indicating
-failure, or wrongfully calling functions out of place.
-
-If you do not provide this callback the library will still return
-an errorcode from the called function, and the mng_getlasterror()
-function can be used to retrieve the other parameters.
-
-This function is currently only provided for convenience, but may
-at some point be used to indicate certain errors may be acceptable,
-and processing should continue.
-
-- mng_bool mng_traceproc (mng_handle hHandle,
- mng_int32 iFuncnr,
- mng_int32 iFuncseq,
- mng_pchar zFuncname)
-
-This function is provided to allow a functional analysis of the
-library. This may be useful if you encounter certain errors and
-cannot determine what the problem is.
-
-Almost all functions inside the library will activate this
-callback with an appropriate function-name at the start and end
-of the function. Please note that large images may generate an
-enormous amount of calls.
-
-- mng_bool mng_processheader (mng_handle hHandle,
- mng_uint32 iWidth,
- mng_uint32 iHeight)
-
-This function is called once the header information of an input-
-image has been processed. At this point the image dimensions are
-available and also some other properties depending on the type
-of the image. Eg. for a MNG the frame-/layercount, playtime &
-simplicity fields are known.
-
-The primary purpose of this callback is to inform the application
-of the size of the image, and for the application to initialize
-the drawing canvas to be used by the library. This is also a good
-point to set the canvas-style. Eg. mng_set_canvasstyle().
-
-- mng_bool mng_processtext (mng_handle hHandle,
- mng_uint8 iType,
- mng_pchar zKeyword,
- mng_pchar zText,
- mng_pchar zLanguage,
- mng_pchar zTranslation)
-
-This callback is activated for each textual chunk in the input-
-image. These are tEXt, zTXt & iTXt. It may be used to retain
-specific comments for presentation to the user.
-
-- mng_bool mng_processsave (mng_handle hHandle)
-- mng_bool mng_processseek (mng_handle hHandle,
- mng_pchar zName)
-
-The purpose of these callbacks is to signal the processing of the
-SAVE & SEEK chunks in a MNG input-file. This may be used in the
-future to specify some special processing. At the moment these
-functions are only provided as a signal.
-
-- mng_ptr mng_getcanvasline (mng_handle hHandle,
- mng_uint32 iLinenr)
-- mng_ptr mng_getbkgdline (mng_handle hHandle,
- mng_uint32 iLinenr)
-- mng_ptr mng_getalphaline (mng_handle hHandle,
- mng_uint32 iLinenr)
-
-These callbacks are used to access the drawing canvas, background
-canvas and an optional separate alpha-channel canvas. The latter is
-used only with the MNG_CANVAS_RGB8_A8 canvas-style.
-
-If the getbkgdline() callback is not supplied the library will
-composite full or partially transparent pixels in the image against
-a specified background color. See mng_set_bgcolor() for more details.
-If a chosen canvas-style includes an alpha-channel, this callback
-is very likely not needed.
-
-The application is responsible for returning a pointer to a line of
-pixels, which should be in the exact format as defined by the call
-to mng_set_canvasstyle() and mng_set_bkgdstyle(), without gaps between
-the representation of each pixel.
-
-- mng_bool mng_refresh (mng_handle hHandle,
- mng_uint32 iX,
- mng_uint32 iY,
- mng_uint32 iWidth,
- mng_uint32 iHeight)
-
-This callback is called when the library has drawn a complete frame
-onto the drawing canvas, and it is ready to be displayed.
-The application is responsible for transferring the drawing canvas
-from memory onto the actual output device.
-
-- mng_uint32 mng_gettickcount (mng_handle hHandle)
-
-This function should return the number of milliseconds on some internal
-clock. The entire animation timing depends heavily on this function,
-1and the number returned should be as accurate as possible.
-
-- mng_bool mng_settimer (mng_handle hHandle,
- mng_uint32 iMsecs)
-
-This callback is activated every time the library requires a "pause".
-Note that the function itself should NOT execute the wait. It should
-simply store the time-field and allow the library to return. Libmng
-will return with the MNG_NEEDTIMERWAIT code, indicating the callback
-was called and it is now time to execute the pause.
-
-After the indicated number of milliseconds have elapsed, the application
-should call mng_display_resume(), to resume the animation as planned.
-
-This method allows for both a real timer or a simple wait command in the
-application. Whichever method you select, both the gettickcount() and
-settimer() callbacks are crucial for proper animation timing.
-
-- mng_bool mng_processgamma (mng_handle hHandle,
- mng_uint32 iGamma)
-- mng_bool mng_processchroma (mng_handle hHandle,
- mng_uint32 iWhitepointx,
- mng_uint32 iWhitepointy,
- mng_uint32 iRedx,
- mng_uint32 iRedy,
- mng_uint32 iGreenx,
- mng_uint32 iGreeny,
- mng_uint32 iBluex,
- mng_uint32 iBluey)
-- mng_bool mng_processsrgb (mng_handle hHandle,
- mng_uint8 iRenderingintent)
-- mng_bool mng_processiccp (mng_handle hHandle,
- mng_uint32 iProfilesize,
- mng_ptr pProfile)
-- mng_bool mng_processarow (mng_handle hHandle,
- mng_uint32 iRowsamples,
- mng_bool bIsRGBA16,
- mng_ptr pRow)
-
-These callbacks are only required when you selected the MNG_APP_CMS
-directive during compilation of the library. See the configuration
-section for more details.
-
-- mng_bool mng_iteratechunk (mng_handle hHandle,
- mng_handle hChunk,
- mng_chunkid iChunkid,
- mng_uint32 iChunkseq)
-
-This callback is only used for the mng_iterate_chunks() function.
-It is called exactly once for each chunk stored.
-
-
-III. Housekeeping
-
-
-> Memory management
-
-The library can use internal memory allocation/deallocation or use
-provided callbacks for its memory management. The choice is made at
-compilation time. See the section on customization for details.
-
-If internal management has been selected, the memory callback functions
-need not be supplied. Even if you do supply them they will not be used.
-The actual code used is similar to the code discussed in the callback
-section:
-
- pPtr = calloc (1, iSize);
-
- free (pPtr);
-
-If your compiler does not support these functions, or you wish to monitor
-the library's use of memory for certain reasons, you can choose to
-compile the library with external memory management. In this case the
-memory callback functions MUST be supplied, and should function as if the
-above code was used.
-
-
-> Initialization
-
-The basic initialization of the library is short and swift:
-
- myhandle = mng_initialize (myuserdata, my_alloc,
- my_free, MNG_NULL);
- if (myhandle == MNG_NULL)
- /* process error */;
-
-The first field is an application-only parameter. It is saved in
-libmng's internal structures and available at all times through the
-mng_get_userdata() function. This is especially handy in callback functions
-if your program may be handling multiple files at the same time.
-
-The second and third field supply the library with the memory callback
-1function entry-points. These are described in more detail in the callback
-section and the previous paragraph.
-
-The fourth and last field may be used to supply the library with the
-entry-point of a trace callback function. For regular use you will not
-need this!
-
-The function returns a handle which will be your ticket to MNG-heaven.
-All other functions rely on this handle. It is the single fixed unique
-reference-point between your application and the library.
-
-You should call the initialization function for each image you wish to
-process simultaneously. If you are processing images consecutively, you can
-reset the internal status of the library with the mng_reset() function.
-This function will clear all internal state variables, free any stored
-chunks and/or objects, etc, etc. Your callbacks and other external parameters
-will be retained.
-
-After you successfully received the handle it is time to set the required
-callbacks. The sections on reading, displaying & writing indicate which
-callbacks are required and which are optional.
-To set the callbacks simply do:
-
- myretcode = mng_setcb_xxxxxx (myhandle, my_xxxxxx);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-Naturally you'd replace the x's with the name of the callback.
-
-
-> Cleanup
-
-Once you've gotten hold of that precious mng_handle, you should always,
-and I mean always, call the cleanup function when you're done.
-Just do:
-
- mng_cleanup (myhandle);
-
-And you're done. There shouldn't be an ounce of memory spilled after
-that call.
-
-Note that if you would like to process multiple files consecutively
-you do not need to do mng_cleanup() / mng_initialize() between each file
-but simply
-
- myretcode = mng_reset (myhandle);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-will suffice. Saves some time and effort, that.
-
-
-> Error handling
-
-From the examples in the previous paragraphs you may have noticed a
-meticulous scheme for error handling. And yes, that's exactly what it is.
-Practically each call simply returns an errorcode, indicating success,
-eg. MNG_NOERROR or failure, anything else but MNG_NEEDMOREDATA and
-MNG_NEEDTIMERWAIT. These latter two will be discussed in more detail in
-their respective fields of interest: the reading section and displaying
-section respectively.
-
-It is the application's responsibility to check the returncode after
-each call. You can call mng_getlasterror() to receive the details of
-the last detected error. This even includes a discriptive error-message
-if you enabled that option during compilation of the library.
-
-Note that after receiving an error it is still possible to call the
-library, but it's also very likely that any following call will fail.
-The only functions deemed to work will be mng_reset() and mng_cleanup().
-Yes, if you abort your program after an error, you should still call
-mng_cleanup().
-
-
-IV. Reading
-
-Reading a MNG, JNG or PNG is fairly easy. It depends slightly on your
-ultimate goal how certain specifics are to be handled, but the basics
-are similar in all cases.
-
-For the read functioins to work you must have compiled the library with
-the MNG_READ_SUPPRT directive. The standard DLL and Shared Library
-have this on by default!
-
-
-> Setup
-
-Naturally you must have initialized the library and be the owner of
-a mng_handle. The following callbacks are essential:
-
- mng_openstream, mng_readdata, mng_closestream
-
-You may optionally define:
-
- mng_errorproc, mng_traceproc
- mng_processheader, mng_processtext
- mng_processsave, mng_processseek
-
-The reading bit will also fail if you are already creating or
-displaying a file. Seems a bit obvious, but I thought I'd mention it,
-just in case.
-
-
-> To suspend or not to suspend
-
-There is one choice you need to make before calling the read function.
-Are you in need of suspension-mode or not?
-
-If you're reading from a disk you most certainly do not need
-suspension-mode. Even the oldest and slowest of disks will be fast
-enough for straight reading.
-
-However, if your input comes from a really slow device, such as a
-dialup-line or the likes, you may opt for suspension-mode. This is done
-by calling
-
- myretcode = mng_set_suspensionmode (myhandle,
- MNG_TRUE);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-Suspension-mode will force the library to use special buffering on the
-input. This allows your application to receive data of arbitrarily length
-and return this in the mng_readdata() callback, without disturbing the
-chunk processing routines of the library.
-
-Suspension-mode does require a little extra care in the main logic of the
-1application. The read function may return with MNG_NEEDMOREDATA when the
-mng_readdata() callback returns less data then it needs to process the
-next chunk. This indicates the application to wait for more data to arrive
-and then resume processing by calling mng_read_resume().
-
-
-> The read HLAPI
-
-The actual reading is just plain simple. Since all I/O is done
-1outside the library through the callbacks, the library can focus on
-its real task. Understanding, checking and labelling the input data!
-
-All you really need to do is this:
-
- myretcode = mng_read (myhandle);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-Of course, if you're on suspension-mode the code is a little more
-complicated:
-
- myretcode = mng_read (myhandle);
-
- while (myretcode == MNG_NEEDMOREDATA) {
- /* wait for input-data to arrive */
- myretcode = mng_read_resume (myhandle);
- }
-
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-This is rather crude and more sophisticated programming methods may
-dictate another approach. Whatever method you decide on, it should
-act as if the above code was in its place.
-
-There is also the mng_readdisplay() function, but this is discussed
-in the displaying section. It functions pretty much as the mng_read()
-function, but also immediately starts displaying the image.
-mng_read_resume() should be replaced by mng_display_resume() in that
-case!
-
-
-> What happens inside
-
-What actually happens inside the library depends on the configuration
-options set during the compilation of the library.
-
-Basically the library will first read the 8-byte file header, to determine
-its validity and the type of image it is about to process. Then it will
-repeatedly read a 4-byte chunk-length and then the remainder of the chunk
-until it either reaches EOF (indicated by the mng_readdata() callback) or
-implicitly decides EOF as it processed the logically last chunk of the
-image.
-
-Applications that require strict conformity and do not allow superfluous
-data after the ending chunk, will need to perform this check in their
-mng_closestream() callback.
-
-Each chunk is then checked on CRC, after which it is handed over to the
-appropriate chunk processing routine. These routines will disect the
-chunk, check the validity of its contents, check its position with respect
-to other chunks, etc, etc.
-
-If everything checks out, the chunk is further processed as follows:
-
-If display support has been selected during compilation, certain pre-display
-initialization will take place.
-
-If chunk-storage support has been selected during compilation, the chunks
-data may be stored in a special internal structure and held for future
-reference.
-
-
-> Storing and accessing chunks
-
-One of the compilation options activates support for chunk storage.
-This option may be useful if you want to examine an image. The directive
-is MNG_STORE_CHUNKS. You must also turn on the MNG_ACCESS_CHUNKS
-directive.
-
-The actual storage facility can be turned on or off with the
-mng_set_storechunks() function. If set to MNG_TRUE, chunks will be
-stored as they are read.
-
-At any point you can then call the mng_iterate_chunks() function
-to iterate through the current list of chunks. This function requires
-a callback which is called for each chunk and receives a specific
-chunk-handle. This chunk-handle can be used to call the appropriate
-mng_getchunk_xxxx() function, to access the chunks properties.
-
-A typical implementation may look like this:
-
- mng_bool my_iteratechunk (mng_handle hHandle,
- mng_handle hChunk,
- mng_chunkid iChunkid,
- mng_uint32 iChunkseq) {
- switch (iChunkid) {
- case MNG_UINT_MHDR : { /* process MHDR */;
- break; }
- case MNG_UINT_FRAM : { /* process FRAM */;
- break; }
-
- ...etc...
-
- case MNG_UINT_HUH : { /* unknown chunk */;
- break; }
- default : { /* duh; forgot one */; }
- }
-
- return MNG_TRUE; /* keep'm coming */
- }
-
-To get to the actual chunk fields of lets say a SHOW chunk you would do:
-
- mng_bool isempty;
- mng_uint16 firstid, lastid;
- mng_uint8 showmode;
-
- myretcode mng_getchunk_show (hHandle, hChunk,
- isempty, firstid,
- lastid, showmode);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-
-V. Displaying
-
-
-> Setup
-
-Assuming you have initialized the library and are the owner of
-a mng_handle. The following callbacks are essential:
-
- mng_getcanvasline, mng_refresh
- mng_gettickcount, mng_settimer
-
-If you wish to use an application supplied background you must supply:
-
- mng_getbkgdline
-
-If you wish to use the MNG_CANVAS_RGB8_A8 canvas style you must supply:
-
- mng_getalphaline
-
-You may optionally define:
-
- mng_errorproc, mng_traceproc
- mng_processheader, mng_processtext
- mng_processsave, mng_processseek
-
-Note that the mng_processheader() callback is optional but will
-be quite significant for proper operation!
-
-Displaying an image will fail if you are creating a file or already
-displaying one. Yes, you can't display it twice!
-
-
-> A word on canvas styles
-
-The canvas style describes how your drawing canvas is made up.
-You must set this before the library actually starts drawing, so
-the mng_processheader() callback is a pretty good place for it.
-
-Currently only 8-bit RGB canvas styles are supported, either with
-or without an alpha channel.
-
-If you like to do alpha composition yourself you can select one of
-the canvas styles that include an alpha channel. You can even have
-a separate alpha canvas by selecting the MNG_CANVAS_RGB8_A8 style.
-
-All styles require a compact model. Eg. MNG_CANVAS_BGR8 requires
-your canvas lines in bgrbgrbgr... storage, where each letter
-represents an 8-bit value of the corresponding color, and each
-threesome makes up the values of one(1) pixel.
-
-The library processes a line at a time, so the canvas lines do not
-actually need to be consecutive in memory.
-
-
-> Alpha composition and application backgrounds
-
-All Network Graphics can be partially transparent. This requires
-special processing if you need to display an image against some
-background. Note that the MNG header (MHDR chunk) contains a
-simplicity field indicating whether transparency information in
-the file is critical or not. This only applies to embedded images,
-which means the full image-frame of the MNG may still contain fully
-transparent pixels!
-
-Depending on your needs you can supply a single background color,
-a background canvas or tell the library to return the alpha-channel
-and do alpha composition yourself.
-
-This is different from the BACK chunk in a MNG, or the bKGD chunk
-in an (embedded) PNG or JNG. The BACK chunk indicates an optional or
-mandatory background color and/or image. The bKGD chunk only indicates
-an optional background color. These chunks indicate the Authors
-preferences. They may be absent in which case you need to supply
-some sort of background yourself.
-
-> Composing against a background color
-
-This is the easiest method. Call the mng_set_bgcolor() function to
-set the values of the red, green and blue component of your preferred
-background color.
-
-Use one of the canvas styles that do not have an alpha-channel, and
-which matches your output requirements.
-
-> Composing against a background canvas
-
-This is somewhat more complicated. You will need to set the
-mng_getbkgdline() callback. This will be called whenever the library
-needs to compose a partially transparent line.
-
-This canvas must hold the background against which the image should
-be composed. Its size must match exactly with the image dimensions
-and thus the drawing canvas!
-
-Use one of the canvas styles that do not have an alpha-channel, and
-which matches your output requirements. The canvas style of the
-background canvas may even differ from the drawing canvas. The library's
-composing will still function properly.
-
-> Composing within the application
-
-If you have the option in your application to draw a (partially)
-transparent canvas to the output device, this option is preferred.
-
-Select one of the canvas styles that do have an alpha-channel.
-The library will now supply the appropriate alpha information,
-allowing the application to compose the image as it sees fit.
-
-
-> Color information and CMS
-
-Network Graphics may, and usually will, contain color-correction
-information. This information is intended to compensate for the
-difference in recording and display devices used.
-
-This document does not address the specifics of color-management.
-See the PNG specification for a more detailed description.
-
-> Using little cms by Marti Maria Saguer
-
-This is the easiest method, providing you can compile the lcms package.
-Select the MNG_FULL_CMS directive during compilation, and sit back and
-relax. The library will take care of all color-correction for you.
-
-> Using an OS- or application-supplied CMS
-
-If you are so lucky to have access to CMS functionality from within
-your application, you may instruct the library to leave color-correction
-to you.
-
-Select the MNG_APP_CMS directive during compilation of the library.
-You MUST also set the following callbacks:
-
- mng_processgamma, mng_processchroma,
- mng_processsrgb, mng_processiccp and
- mng_processarow
-
-The last callback is called when the library needs you to correct
-an arbitrary line of pixels. The other callbacks are called when
-the corresponding color-information is encountered in the file.
-You must store this information somewhere for use in the
-mng_processarow() callback.
-
-> Using gamma-only correction
-
-This isn't a preferred method, but it's better than no correction
-at all. Gamma-only correction will at least compensate for
-gamma-differences between the original recorder and your output device.
-
-Select the MNG_GAMMA_ONLY directive during compilation
-of the library. Your compiler MUST support fp operations.
-
-> No color correction
-
-Ouch. This is really bad. This is the least preferred method,
-but may be necessary if your system cannot use lcms, doesn't
-have its own CMS, and does not allow fp operations, ruling out
-the gamma-only option.
-
-Select the MNG_NO_CMS directive during compilation.
-Images will definitely not be displayed as seen by the Author!!!
-
-
-> Animations and timing
-
-Animations require some form of timing support. The library relies
-on two callbacks for this purpose. The mng_gettickcount() and
-mng_settimer() callbacks. mng_gettickcount() is used to determine
-the passing of time in milliseconds since the beginning of the
-animation. This is also used to compensate during suspension-mode
-if you are using the mng_readdisplay() function to read & display
-the file simultaneously.
-
-The callback may return an arbitrary number of milliseconds, but
-this number must increase proportionaly between calls. Most modern
-systems will have some tickcount() function which derives its
-input from an internal clock. The value returned from this function
-is more than adequate for libmng.
-
-The mng_settimer() callback is called when the library determines
-a little "pause" is required before rendering another frame of the
-animation. The pause interval is also expressed in milliseconds.
-Your application should store this value and return immediately.
-The library will then make appropriate arrangements to store its
-internal state and returns to your application with the
-MNG_NEEDTIMERWAIT code.
-
-At that point you should suspend processing and wait the given
-interval. Please use your OS features for this. Do not engage some
-sort of loop. That is real bad programming practice. Most modern
-systems will have some timing functions. A simple wait() function
-may suffice, but this may prevent your applications main-task from
-running, and possibly prevent the actual update of your output device.
-
-
-> The mng_refresh() callback
-
-The mng_refresh() callback is called whenever the library has
-"finished" drawing a new frame onto your canvas, and just before it
-will call the mng_settimer() callback.
-
-This allows you to perform some actions necessary to "refresh" the
-canvas onto your output device. Please do NOT suspend processing
-inside this callback. This must be handled after the mng_settimer()
-callback!
-
-
-> Displaying while reading
-
-This method is preferred if you are reading from a slow input device
-(such as a dialup-line) and you wish to start displaying something
-as quickly as possible. This functionality is provided mainly for
-browser-type applications but may be appropriate for other
-applications as well.
-
-The method is usually used in unison with the suspension-mode of
-the read module. A typical implementation would look like this:
-
- /* initiale library and set required callbacks */
-
- /* activate suspension-mode */
- myretcode = mng_set_suspensionmode (myhandle,
- MNG_TRUE);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
- myretcode = mng_readdisplay (myhandle);
-
- while ((myretcode == MNG_NEEDMOREDATA) ||
- (myretcode == MNG_NEEDTIMERWAIT)) {
- if (myretcode == MNG_NEEDMOREDATA)
- /* wait for more input-data */;
- else
- /* wait for timer interval */;
-
- myretcode = mng_display_resume (myhandle);
- }
-
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-More advanced programming methods may require a different approach,
-but the final result should function as in the code above.
-
-
-> Displaying after reading
-
-This method is used to display a file that was previously read.
-It is primarily meant for viewers with direct file access, such as
-1a local harddisk.
-
-Once you have successfully read the file, all you need to do is:
-
- myretcode = mng_display (myhandle);
-
- while (myretcode == MNG_NEEDTIMERWAIT) {
- /* wait for timer interval */;
- myretcode = mng_display_resume (myhandle);
- }
-
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-Again, more advanced programming methods may require a different
-approach, but the final result should function as in the code above.
-
-
-> Display manipulation
-
-Several HLAPI functions are provided to allow a user to manipulate
-the normal flow of an animation.
-
-- mng_display_freeze (mng_handle hHandle)
-
-This will "freeze" the animation in place.
-
-- mng_display_resume (mng_handle hHandle)
-
-This function can be used to resume a frozen animation, or to force
-the library to advance the animation to the next frame.
-
-- mng_display_reset (mng_handle hHandle)
-
-This function will "reset" the animation into its pristine state.
-Calling mng_display() afterwards will re-display the animation
-from the first frame.
-
-- mng_display_golayer (mng_handle hHandle,
- mng_uint32 iLayer)
-- mng_display_goframe (mng_handle hHandle,
- mng_uint32 iFrame)
-- mng_display_goplaytime (mng_handle hHandle,
- mng_uint32 iPlaytime)
-
-These three functions can be used to "jump" to a specific layer, frame
-or timeslot in the animation. You must "freeze" the animation before
-using any of these functions.
-
-All above functions may only be called during a timer interval!
-It is the applications responsibility to cleanup any resources with
-respect to the timer wait.
-
-
-VI. Writing
-
-The main focus of the library lies in its displaying capabilites.
-But it does offer writing support as well.
-You can create and write a file, or you can write a file you
-have previously read, providing the storage of chunks was enabled
-and active.
-
-For this to work you must have compiled the library with the
-MNG_WRITE_SUPPO1RT and MNG_ACCESS_CHUNKS directives. The standard DLL and
-Shared Library have this on by default!
-
-
-> Setup
-
-As always you must have initialized the library and be the owner of
-a mng_handle. The following callbacks are essential:
-
- mng_openstream, mng_writedata, mng_closestream
-
-You can optionally define:
-
- mng_errorproc, mng_traceproc
-
-The creation and writing functions will fail if you are in the middle
-of reading, creating or writing a file.
-
-
-> Creating a new file
-
-To start a new file the library must be in its initial state.
-First you need to tell the library your intentions:
-
- myretcode = mng_create (myhandle);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-After that you start adding the appropriate chunks:
-
- myretcode = mng_putchunk_mhdr (myhandle, ...);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-And so on, and so forth. Note that the library will automatically signal
-the logical end of the file by the ending chunk. Also the first chunk
-will indicate the library the filetype (eg. PNG, JNG or MNG) and force
-the proper signature when writing the file.
-
-The code above can be simplified, as you can always get the last errorcode
-by using the mng_getlasterror() function:
-
- if ( (mng_putchunk_xxxx (myhandle, ...)) or
- (mng_putchunk_xxxx (myhandle, ...)) or
- ...etc... )
- /* process error */;
-
-Please note that you must have a pretty good understanding of the chunk
-specification. Unlike the read functions, there are virtually no checks,
-so it is quite possible to write completely wrong files.
-It is a good practice to read back your file into the library to verify
-its integrity.
-
-Once you've got all the chunks added, all you do is:
-
- myretcode mng_write (myhandle);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-And presto. You're done. The real work is of course carried out in
-your callbacks. Note that this is a single operation as opposed to
-the read & display functions that may return with MNG_NEEDMOREDATA
-and/or MNG_NEEDTIMERWAIT. The write function just does the job, and
-only returns after it's finished or if it encounters some
-unrecoverable error.
-
-
-> Writing a previously read file
-
-If you have already successfully read a file, you can use the library to
-write it out as a copy or something. You MUST have compiled the library
-with the MNG_STORE_CHUNKS directive, and you must have done
-mng_set_storechunks (myhandle, MNG_TRUE).
-
-This doesn't require the MNG_ACCESS_CHUNKS directive, unless you want
-to fiddle with the chunks as well.
-
-Again all you need to do is:
-
- myretcode mng_write (myhandle);
- if (myretcode != MNG_NOERROR)
- /* process error */;

-.SH NAME
-jng \- JPEG Network Graphics (JNG) sub-format
-.SH DESCRIPTION
-JNG (JPEG Network Graphics) is a sub-format of the MNG (Multiple-image
-Network Graphics) format. As with MNG it extends on the features of the
-popular PNG (Portable Network Graphics) image-format.
-.br
-
-This sub-format was designed to support a lossy compression-method.
-It is based completely on the JPEG specification. It adds the high-compression
-ratios of JPEG for photographic images.
-
-As a member of the Network Graphics family, JNG was deemed adequate as a
-stand-alone format as it extends the JPEG format with color-correction and
-transparency features.

-.TH LIBMNG 3 "January 30th, 2005"
-.SH NAME
-libmng \- Multiple-image Network Graphics (MNG) Reference Library 1.0.9
-.SH SYNOPSIS
-\fI\fB
-
-\fB#include <libmng.h>\fP
-
-
-.SH DESCRIPTION
-The
-.I libmng
-library supports decoding, displaying, encoding, and various other
-manipulations of the Multiple-image Network Graphics (MNG) format
-image files. It uses the
-.IR zlib(3)
-compression library, and optionally the JPEG library by the Independant
-JPEG Group (IJG) and/or lcms (little cms), a color-management library
-by Marti Maria Saguer.
-
-
-.SH I. Introduction
-
-This file describes how to use and modify the MNG reference library
-(known as libmng) for your own use. There are seven sections to this
-file: introduction, callbacks, housekeeping, reading, displaying,
-writing, and modification and configuration notes for various special
-platforms. We assume that libmng is already installed; see the
-INSTALL.README file for instructions on how to install libmng.
-
-Libmng was written to support and promote the MNG specification.
-
-The MNG-1.0 specification is available at
-<http://www.libpng.org/pub/mng/spec/>.
-
-Other information about MNG can be found at the MNG home page,
-<http://www.libpng.org/pub/mng/>.
-The latest version of libmng can be found at its own homepage at
-<http://www.libmng.com/>.
-
-In most cases the library will not need to be changed.
-For standardization purposes the library contains both a Windows DLL
-and a makefile for building a shared library (SO). The library is
-written in C, but an interface for Borland Delphi is also available.
-
-Libmng has been designed to handle multiple sessions at one time,
-to be easily modifiable, to be portable to the vast majority of
-machines (ANSI, K&R, 32-, and 64-bit) available, and to be easy
-to use.
-
-Libmng uses zlib for its compression and decompression of MNG files.
-Further information about zlib, and the latest version of zlib, can be
-found at the zlib home page, <http://www.zlib.org/>.
-The zlib compression utility is a general purpose utility that is
-useful for more than MNG/PNG files, and can be used without libmng.
-See the documentation delivered with zlib for more details.
-
-Libmng optionally uses the JPEG library by the Independant JPEG Group
-(IJG). This library is used for the JNG sub-format, which is part of
-the MNG specification, and allows for inclusion of JPEG decoded and
-thus highly compressed (photographic) images.
-Further information about the IJG JPEG library and the latest sources
-can be found at <http://www.ijg.org/>.
-
-Libmng can also optionally use the lcms (little CMS) library by
-Marti Maria Saguer. This library provides an excellent color-management
-system (CMS), which gives libmng the ability to provide full
-color-correction for images with the proper color-information encoded.
-Further information and the latest sources can be found at
-<http://www.littlecms.com/>.
-
-Libmng is thread safe, provided the threads are using different
-handles as returned by the initialization call.
-Each thread should have its own handle and thus its own image.
-Libmng does not protect itself against two threads using the
-same instance of a handle.
-
-The libmng.h header file is the single reference needed for programming
-with libmng:
-
-#include <libmng.h>
-
-
-.SH II. Callbacks
-
-Libmng makes extensive use of callback functions. This is meant to
-keep the library as platform-independant and flexible as possible.
-Actually, the first call you will make to the library, already contains
-three parameters you can use to provide callback entry-points.
-
-Most functions must return a mng_bool (boolean). Returning MNG_FALSE
-indicates the library the callback failed in some way and the library
-will immediately return from whatever it was doing back to the
-application. Returning MNG_TRUE indicates there were no problems and
-processing can continue.
-
-Let's step through each of the possible callbacks. The sections on
-reading, displaying and writing will also explain which callbacks are
-needed when and where.
-
-\- mng_ptr mng_memalloc (mng_size_t iLen)
-
-A very basic function which the library uses to allocate a memory-block
-with the given size. A typical implementation would be:
-
- mng_ptr my_alloc (mng_size_t iLen) {
- return calloc (1, iLen);
- }
-
-Note that the library requires you to zero-out the memory-block!!!
-
-\- void mng_memfree (mng_ptr pPtr,
- mng_size_t iLen)
-
-Counterpart of the previous function. Typically:
-
- void my_free (mng_ptr pPtr, mng_size_t iLen) {
- free (pPtr);
- }
-
-\- mng_bool mng_openstream (mng_handle hHandle)
-
-\- mng_bool mng_closestream (mng_handle hHandle)
-
-These are called by the library just before it starts to process
-(either read or write) a file and just after the processing stops.
-This is the recommended place to do I/O initialization & finalization.
-Whether you do or not, is up to you. The library does not put any
-meaning into the calls. They are simply provided for your convenience.
-
-\- mng_bool mng_readdata (mng_handle hHandle,
- mng_ptr pBuf,
- mng_uint32 iBuflen,
- mng_uint32p pRead)
-
-This function is called when the library needs some more input while
-reading an image. The reading process supports two modes:
-Suspension-mode (SMOD) and non-suspension-mode (NSMOD).
-See mng_set_suspensionmode() for a more detailed description.
-
-In NSMOD, the library requires you to return exactly the amount of bytes
-requested (= iBuflen). Any lesser amount indicates the input file
-is exhausted and the library will return a MNG_UNEXPECTEDEOF errorcode.
-
-In SMOD, you may return a smaller amount of bytes than requested.
-This tells the library it should temporarily wait for more input to
-arrive. The lib will return with MNG_NEEDMOREDATA, and will expect a
-call to mng_read_resume() or mng_display_resume() next, as soon as
-more input-data has arrived.
-
-For NSMOD this function could be as simple as:
-
- mng_bool my_read (mng_handle hHandle,
- mng_ptr pBuf,
- mng_uint32 iBuflen,
- mng_uint32p pRead) {
- *pRead = fread (pBuf, 1, iBuflen, myfile);
- return MNG_TRUE;
- }
-
-\- mng_bool mng_writedata (mng_handle hHandle,
- mng_ptr pBuf,
- mng_uint32 iBuflen,
- mng_uint32p pWritten)
-
-This function is called during the mng_write() function to actually
-output data to the file. There is no suspension-mode during write,
-so the application must return the exact number of bytes the library
-requests to be written.
-
-A typical implementation could be:
-
- mng_bool my_write (mng_handle hHandle,
- mng_ptr pBuf,
- mng_uint32 iBuflen,
- mng_uint32p pWritten) {
- *pWritten = fwrite (pBuf, 1, iBuflen, myfile);
- return MNG_TRUE;
- }
-
-\- mng_bool mng_errorproc (mng_handle hHandle,
- mng_int32 iErrorcode,
- mng_int8 iSeverity,
- mng_chunkid iChunkname,
- mng_uint32 iChunkseq,
- mng_int32 iExtra1,
- mng_int32 iExtra2,
- mng_pchar zErrortext)
-
-This function is called whenever an error is detected inside the
-library. This may be caused by invalid input, callbacks indicating
-failure, or wrongfully calling functions out of place.
-
-If you do not provide this callback the library will still return
-an errorcode from the called function, and the mng_getlasterror()
-function can be used to retrieve the other parameters.
-
-This function is currently only provided for convenience, but may
-at some point be used to indicate certain errors may be acceptable,
-and processing should continue.
-
-\- mng_bool mng_traceproc (mng_handle hHandle,
- mng_int32 iFuncnr,
- mng_int32 iFuncseq,
- mng_pchar zFuncname)
-
-This function is provided to allow a functional analysis of the
-library. This may be useful if you encounter certain errors and
-cannot determine what the problem is.
-
-Almost all functions inside the library will activate this
-callback with an appropriate function-name at the start and end
-of the function. Please note that large images may generate an
-enormous amount of calls.
-
-\- mng_bool mng_processheader (mng_handle hHandle,
- mng_uint32 iWidth,
- mng_uint32 iHeight)
-
-This function is called once the header information of an input-
-image has been processed. At this point the image dimensions are
-available and also some other properties depending on the type
-of the image. Eg. for a MNG the frame-/layercount, playtime &
-simplicity fields are known.
-
-The primary purpose of this callback is to inform the application
-of the size of the image, and for the application to initialize
-the drawing canvas to be used by the library. This is also a good
-point to set the canvas-style. Eg. mng_set_canvasstyle().
-
-\- mng_bool mng_processtext (mng_handle hHandle,
- mng_uint8 iType,
- mng_pchar zKeyword,
- mng_pchar zText,
- mng_pchar zLanguage,
- mng_pchar zTranslation)
-
-This callback is activated for each textual chunk in the input-
-image. These are tEXt, zTXt & iTXt. It may be used to retain
-specific comments for presentation to the user.
-
-\- mng_bool mng_processsave (mng_handle hHandle)
-
-\- mng_bool mng_processseek (mng_handle hHandle,
- mng_pchar zName)
-
-The purpose of these callbacks is to signal the processing of the
-SAVE & SEEK chunks in a MNG input-file. This may be used in the
-future to specify some special processing. At the moment these
-functions are only provided as a signal.
-
-\- mng_ptr mng_getcanvasline (mng_handle hHandle,
- mng_uint32 iLinenr)
-
-\- mng_ptr mng_getbkgdline (mng_handle hHandle,
- mng_uint32 iLinenr)
-
-\- mng_ptr mng_getalphaline (mng_handle hHandle,
- mng_uint32 iLinenr)
-
-These callbacks are used to access the drawing canvas, background
-canvas and an optional separate alpha-channel canvas. The latter is
-used only with the MNG_CANVAS_RGB8_A8 canvas-style.
-
-If the getbkgdline() callback is not supplied the library will
-composite fully or partially transparent pixels in the image against
-a specified background color. See mng_set_bgcolor() for more details.
-If a chosen canvas-style includes an alpha-channel, this callback
-is very likely not needed.
-
-The application is responsible for returning a pointer to a line of
-pixels, which should be in the exact format as defined by the call
-to mng_set_canvasstyle() and mng_set_bkgdstyle(), without gaps between
-the representation of each pixel, unless specified by the canvas-style.
-
-\- mng_bool mng_refresh (mng_handle hHandle,
- mng_uint32 iX,
- mng_uint32 iY,
- mng_uint32 iWidth,
- mng_uint32 iHeight)
-
-This callback is called when the library has drawn a complete frame
-onto the drawing canvas, and it is ready to be displayed.
-The application is responsible for transferring the drawing canvas
-from memory onto the actual output device.
-
-\- mng_uint32 mng_gettickcount (mng_handle hHandle)
-
-This function should return the number of milliseconds on some internal
-clock. The entire animation timing depends heavily on this function,
-and the number returned should be as accurate as possible.
-
-\- mng_bool mng_settimer (mng_handle hHandle,
- mng_uint32 iMsecs)
-
-This callback is activated every time the library requires a "pause".
-Note that the function itself should NOT execute the wait. It should
-simply store the time-field and allow the library to return. Libmng
-will return with the MNG_NEEDTIMERWAIT code, indicating the callback
-was called and it is now time to execute the pause.
-
-After the indicated number of milliseconds have elapsed, the application
-should call mng_display_resume(), to resume the animation as planned.
-
-This method allows for both a real timer or a simple wait command in the
-application. Whichever method you select, both the gettickcount() and
-settimer() callbacks are crucial for proper animation timing.
-
-\- mng_bool mng_processgamma (mng_handle hHandle,
- mng_uint32 iGamma)
-
-\- mng_bool mng_processchroma (mng_handle hHandle,
- mng_uint32 iWhitepointx,
- mng_uint32 iWhitepointy,
- mng_uint32 iRedx,
- mng_uint32 iRedy,
- mng_uint32 iGreenx,
- mng_uint32 iGreeny,
- mng_uint32 iBluex,
- mng_uint32 iBluey)
-
-\- mng_bool mng_processsrgb (mng_handle hHandle,
- mng_uint8 iRenderingintent)
-
-\- mng_bool mng_processiccp (mng_handle hHandle,
- mng_uint32 iProfilesize,
- mng_ptr pProfile)
-
-\- mng_bool mng_processarow (mng_handle hHandle,
- mng_uint32 iRowsamples,
- mng_bool bIsRGBA16,
- mng_ptr pRow)
-
-These callbacks are only required when you selected the MNG_APP_CMS
-directive during compilation of the library. See the configuration
-section for more details.
-
-\- mng_bool mng_iteratechunk (mng_handle hHandle,
- mng_handle hChunk,
- mng_chunkid iChunkid,
- mng_uint32 iChunkseq)
-
-This callback is only used for the mng_iterate_chunks() function.
-It is called exactly once for each chunk stored.
-
-
-.SH III. Housekeeping
-
-
-.SS Memory management
-
-The library can use internal memory allocation/deallocation or use
-provided callbacks for its memory management. The choice is made at
-compilation time. See the section on customization for details.
-
-If internal management has been selected, the memory callback functions
-need not be supplied. Even if you do supply them they will not be used.
-The actual code used is similar to the code discussed in the callback
-section:
-
- pPtr = calloc (1, iLen);
-
- free (pPtr);
-
-If your compiler does not support these functions, or you wish to monitor
-the library's use of memory for certain reasons, you can choose to
-compile the library with external memory management. In this case the
-memory callback functions MUST be supplied, and should function as if the
-above code was used.
-
-
-.SS Initialization
-
-The basic initialization of the library is short and swift:
-
- myhandle = mng_initialize (myuserdata, my_alloc,
- my_free, MNG_NULL);
- if (myhandle == MNG_NULL)
- /* process error */;
-
-The first field is an application-only parameter. It is saved in
-libmng's internal structures and available at all times through the
-mng_get_userdata() function. This is especially handy in callback functions
-if your program may be handling multiple files at the same time.
-
-The second and third field supply the library with the memory callback
-function entry-points. These are described in more detail in the callback
-section and the previous paragraph.
-
-The fourth and last field may be used to supply the library with the
-entry-point of a trace callback function. For regular use you will not
-need this!
-
-The function returns a handle which will be your ticket to MNG-heaven.
-All other functions rely on this handle. It is the single fixed unique
-reference-point between your application and the library.
-
-You should call the initialization function for each image you wish to
-process simultaneously. If you are processing images consecutively, you can
-reset the internal status of the library with the mng_reset() function.
-This function will clear all internal state variables, free any stored
-chunks and/or objects, etc, etc. Your callbacks and other external parameters
-will be retained.
-
-After you successfully received the handle it is time to set the required
-callbacks. The sections on reading, displaying & writing indicate which
-callbacks are required and which are optional.
-To set the callbacks simply do:
-
- myretcode = mng_setcb_xxxxxx (myhandle, my_xxxxxx);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-Naturally you'd replace the x's with the name of the callback.
-
-
-.SS Cleanup
-
-Once you've gotten hold of that precious mng_handle, you should always,
-and I mean always, call the cleanup function when you're done.
-Just do:
-
- mng_cleanup (myhandle);
-
-And you're done. There shouldn't be an ounce of memory spilled after
-that call.
-
-Note that if you would like to process multiple files consecutively
-you do not need to do mng_cleanup() / mng_initialize() between each file
-but simply
-
- myretcode = mng_reset (myhandle);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-will suffice. Saves some time and effort, that.
-
-
-.SS Error handling
-
-From the examples in the previous paragraphs you may have noticed a
-meticulous scheme for error handling. And yes, that's exactly what it is.
-Practically each call simply returns an errorcode, indicating success,
-eg. MNG_NOERROR or failure, anything else but MNG_NEEDMOREDATA and
-MNG_NEEDTIMERWAIT. These latter two will be discussed in more detail in
-their respective fields of interest: the reading section and displaying
-section respectively.
-
-It is the application's responsibility to check the returncode after
-each call. You can call mng_getlasterror() to receive the details of
-the last detected error. This even includes a discriptive error-message
-if you enabled that option during compilation of the library.
-
-Note that after receiving an error it is still possible to call the
-library, but it's also very likely that any following call will fail.
-The only functions deemed to work will be mng_reset() and mng_cleanup().
-Yes, if you abort your program after an error, you should still call
-mng_cleanup().
-
-
-.SH IV. Reading
-
-Reading a MNG, JNG or PNG is fairly easy. It depends slightly on your
-ultimate goal how certain specifics are to be handled, but the basics
-are similar in all cases.
-
-For the read functioins to work you must have compiled the library with
-the MNG_READ_SUPPRT directive. The standard DLL and Shared Library
-have this on by default!
-
-
-.SS Setup
-
-Naturally you must have initialized the library and be the owner of
-a mng_handle. The following callbacks are essential:
-
- mng_openstream, mng_readdata, mng_closestream
-
-You may optionally define:
-
- mng_errorproc, mng_traceproc
- mng_processheader, mng_processtext
- mng_processsave, mng_processseek
-
-The reading bit will also fail if you are already creating or
-displaying a file. Seems a bit obvious, but I thought I'd mention it,
-just in case.
-
-
-.SS To suspend or not to suspend
-
-There is one choice you need to make before calling the read function.
-Are you in need of suspension-mode or not?
-
-If you're reading from a disk you most certainly do not need
-suspension-mode. Even the oldest and slowest of disks will be fast
-enough for straight reading.
-
-However, if your input comes from a really slow device, such as a
-dialup-line or the likes, you may opt for suspension-mode. This is done
-by calling
-
- myretcode = mng_set_suspensionmode (myhandle,
- MNG_TRUE);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-Suspension-mode will force the library to use special buffering on the
-input. This allows your application to receive data of arbitrarily length
-and return this in the mng_readdata() callback, without disturbing the
-chunk processing routines of the library.
-
-Suspension-mode does require a little extra care in the main logic of the
-application. The read function may return with MNG_NEEDMOREDATA when the
-mng_readdata() callback returns less data then it needs to process the
-next chunk. This indicates the application to wait for more data to arrive
-and then resume processing by calling mng_read_resume().
-
-
-.SS The read HLAPI
-
-The actual reading is just plain simple. Since all I/O is done
-outside the library through the callbacks, the library can focus on
-its real task. Understanding, checking and labelling the input data!
-
-All you really need to do is this:
-
- myretcode = mng_read (myhandle);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-Of course, if you're on suspension-mode the code is a little more
-complicated:
-
- myretcode = mng_read (myhandle);
-
- while (myretcode == MNG_NEEDMOREDATA) {
- /* wait for input-data to arrive */
- myretcode = mng_read_resume (myhandle);
- }
-
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-This is rather crude and more sophisticated programming methods may
-dictate another approach. Whatever method you decide on, it should
-act as if the above code was in its place.
-
-There is also the mng_readdisplay() function, but this is discussed
-in the displaying section. It functions pretty much as the mng_read()
-function, but also immediately starts displaying the image.
-mng_read_resume() should be replaced by mng_display_resume() in that
-case!
-
-
-.SS What happens inside
-
-What actually happens inside the library depends on the configuration
-options set during the compilation of the library.
-
-Basically the library will first read the 8-byte file header, to determine
-its validity and the type of image it is about to process. Then it will
-repeatedly read a 4-byte chunk-length and then the remainder of the chunk
-until it either reaches EOF (indicated by the mng_readdata() callback) or
-implicitly decides EOF as it processed the logically last chunk of the
-image.
-
-Applications that require strict conformity and do not allow superfluous
-data after the ending chunk, will need to perform this check in their
-mng_closestream() callback.
-
-Each chunk is then checked on CRC, after which it is handed over to the
-appropriate chunk processing routine. These routines will disect the
-chunk, check the validity of its contents, check its position with respect
-to other chunks, etc, etc.
-
-If everything checks out, the chunk is further processed as follows:
-
-If display support has been selected during compilation, certain pre-display
-initialization will take place.
-
-If chunk-storage support has been selected during compilation, the chunks
-data may be stored in a special internal structure and held for future
-reference.
-
-
-.SS Storing and accessing chunks
-
-One of the compilation options activates support for chunk storage.
-This option may be useful if you want to examine an image. The directive
-is MNG_STORE_CHUNKS. You must also turn on the MNG_ACCESS_CHUNKS
-directive.
-
-The actual storage facility can be turned on or off with the
-mng_set_storechunks() function. If set to MNG_TRUE, chunks will be
-stored as they are read.
-
-At any point you can then call the mng_iterate_chunks() function
-to iterate through the current list of chunks. This function requires
-a callback which is called for each chunk and receives a specific
-chunk-handle. This chunk-handle can be used to call the appropriate
-mng_getchunk_xxxx() function, to access the chunks properties.
-
-A typical implementation may look like this:
-
- mng_bool my_iteratechunk (mng_handle hHandle,
- mng_handle hChunk,
- mng_chunkid iChunkid,
- mng_uint32 iChunkseq) {
- switch (iChunkid) {
- case MNG_UINT_MHDR : { /* process MHDR */;
- break; }
- case MNG_UINT_FRAM : { /* process FRAM */;
- break; }
-
- ...etc...
-
- case MNG_UINT_HUH : { /* unknown chunk */;
- break; }
- default : { /* duh; forgot one */; }
- }
-
- return MNG_TRUE; /* keep'm coming */
- }
-
-To get to the actual chunk fields of lets say a SHOW chunk you would do:
-
- mng_bool isempty;
- mng_uint16 firstid, lastid;
- mng_uint8 showmode;
-
- myretcode mng_getchunk_show (hHandle, hChunk,
- isempty, firstid,
- lastid, showmode);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-
-.SH V. Displaying
-
-
-.SS Setup
-
-Assuming you have initialized the library and are the owner of
-a mng_handle. The following callbacks are essential:
-
- mng_getcanvasline, mng_refresh
- mng_gettickcount, mng_settimer
-
-If you wish to use an application supplied background you must supply:
-
- mng_getbkgdline
-
-If you wish to use the MNG_CANVAS_RGB8_A8 canvas style you must supply:
-
- mng_getalphaline
-
-You may optionally define:
-
- mng_errorproc, mng_traceproc
- mng_processheader, mng_processtext
- mng_processsave, mng_processseek
-
-Note that the mng_processheader() callback is optional but will
-be quite significant for proper operation!
-
-Displaying an image will fail if you are creating a file or already
-displaying one. Yes, you can't display it twice!
-
-
-.SS A word on canvas styles
-
-The canvas style describes how your drawing canvas is made up.
-You must set this before the library actually starts drawing, so
-the mng_processheader() callback is a pretty good place for it.
-
-Currently only 8-bit RGB canvas styles are supported, either with
-or without an alpha channel.
-
-If you like to do alpha composition yourself you can select one of
-the canvas styles that include an alpha channel. You can even have
-a separate alpha canvas by selecting the MNG_CANVAS_RGB8_A8 style.
-
-All styles require a compact model. Eg. MNG_CANVAS_BGR8 requires
-your canvas lines in bgrbgrbgr... storage, where each letter
-represents an 8-bit value of the corresponding color, and each
-threesome makes up the values of one(1) pixel.
-
-The library processes a line at a time, so the canvas lines do not
-actually need to be consecutive in memory.
-
-
-.SS Alpha composition and application backgrounds
-
-All Network Graphics can be partially transparent. This requires
-special processing if you need to display an image against some
-background. Note that the MNG header (MHDR chunk) contains a
-simplicity field indicating whether transparency information in
-the file is critical or not. This only applies to embedded images,
-which means the full image-frame of the MNG may still contain fully
-transparent pixels!
-
-Depending on your needs you can supply a single background color,
-a background canvas or tell the library to return the alpha-channel
-and do alpha composition yourself.
-
-This is different from the BACK chunk in a MNG, or the bKGD chunk
-in an (embedded) PNG or JNG. The BACK chunk indicates an optional or
-mandatory background color and/or image. The bKGD chunk only indicates
-an optional background color. These chunks indicate the Authors
-preferences. They may be absent in which case you need to supply
-some sort of background yourself.
-
-.SS Composing against a background color
-
-This is the easiest method. Call the mng_set_bgcolor() function to
-set the values of the red, green and blue component of your preferred
-background color.
-
-Use one of the canvas styles that do not have an alpha-channel, and
-which matches your output requirements.
-
-.SS Composing against a background canvas
-
-This is somewhat more complicated. You will need to set the
-mng_getbkgdline() callback. This will be called whenever the library
-needs to compose a partially transparent line.
-
-This canvas must hold the background against which the image should
-be composed. Its size must match exactly with the image dimensions
-and thus the drawing canvas!
-
-Use one of the canvas styles that do not have an alpha-channel, and
-which matches your output requirements. The canvas style of the
-background canvas may even differ from the drawing canvas. The library's
-composing will still function properly.
-
-.SS Composing within the application
-
-If you have the option in your application to draw a (partially)
-transparent canvas to the output device, this option is preferred.
-
-Select one of the canvas styles that do have an alpha-channel.
-The library will now supply the appropriate alpha information,
-allowing the application to compose the image as it sees fit.
-
-
-.SS Color information and CMS
-
-Network Graphics may, and usually will, contain color-correction
-information. This information is intended to compensate for the
-difference in recording and display devices used.
-
-This document does not address the specifics of color-management.
-See the PNG specification for a more detailed description.
-
-.SS Using little cms by Marti Maria Saguer
-
-This is the easiest method, providing you can compile the lcms package.
-Select the MNG_FULL_CMS directive during compilation, and sit back and
-relax. The library will take care of all color-correction for you.
-
-.SS Using an OS- or application-supplied CMS
-
-If you are so lucky to have access to CMS functionality from within
-your application, you may instruct the library to leave color-correction
-to you.
-
-Select the MNG_APP_CMS directive during compilation of the library.
-You MUST also set the following callbacks:
-
- mng_processgamma, mng_processchroma,
- mng_processsrgb, mng_processiccp and
- mng_processarow
-
-The last callback is called when the library needs you to correct
-an arbitrary line of pixels. The other callbacks are called when
-the corresponding color-information is encountered in the file.
-You must store this information somewhere for use in the
-mng_processarow() callback.
-
-.SS Using gamma-only correction
-
-This isn't a preferred method, but it's better than no correction
-at all. Gamma-only correction will at least compensate for
-gamma-differences between the original recorder and your output device.
-
-Select the MNG_GAMMA_ONLY directive during compilation
-of the library. Your compiler MUST support fp operations.
-
-.SS No color correction
-
-Ouch. This is really bad. This is the least preferred method,
-but may be necessary if your system cannot use lcms, doesn't
-have its own CMS, and does not allow fp operations, ruling out
-the gamma-only option.
-
-Select the MNG_NO_CMS directive during compilation.
-Images will definitely not be displayed as seen by the Author!!!
-
-
-.SS Animations and timing
-
-Animations require some form of timing support. The library relies
-on two callbacks for this purpose. The mng_gettickcount() and
-mng_settimer() callbacks. mng_gettickcount() is used to determine
-the passing of time in milliseconds since the beginning of the
-animation. This is also used to compensate during suspension-mode
-if you are using the mng_readdisplay() function to read & display
-the file simultaneously.
-
-The callback may return an arbitrary number of milliseconds, but
-this number must increase proportionaly between calls. Most modern
-systems will have some tickcount() function which derives its
-input from an internal clock. The value returned from this function
-is more than adequate for libmng.
-
-The mng_settimer() callback is called when the library determines
-a little "pause" is required before rendering another frame of the
-animation. The pause interval is also expressed in milliseconds.
-Your application should store this value and return immediately.
-The library will then make appropriate arrangements to store its
-internal state and returns to your application with the
-MNG_NEEDTIMERWAIT code.
-
-At that point you should suspend processing and wait the given
-interval. Please use your OS features for this. Do not engage some
-sort of loop. That is real bad programming practice. Most modern
-systems will have some timing functions. A simple wait() function
-may suffice, but this may prevent your applications main-task from
-running, and possibly prevent the actual update of your output device.
-
-
-.SS The mng_refresh() callback
-
-The mng_refresh() callback is called whenever the library has
-"finished" drawing a new frame onto your canvas, and just before it
-will call the mng_settimer() callback.
-
-This allows you to perform some actions necessary to "refresh" the
-canvas onto your output device. Please do NOT suspend processing
-inside this callback. This must be handled after the mng_settimer()
-callback!
-
-
-.SS Displaying while reading
-
-This method is preferred if you are reading from a slow input device
-(such as a dialup-line) and you wish to start displaying something
-as quickly as possible. This functionality is provided mainly for
-browser-type applications but may be appropriate for other
-applications as well.
-
-The method is usually used in unison with the suspension-mode of
-the read module. A typical implementation would look like this:
-
- /* initiale library and set required callbacks */
-
- /* activate suspension-mode */
- myretcode = mng_set_suspensionmode (myhandle,
- MNG_TRUE);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
- myretcode = mng_readdisplay (myhandle);
-
- while ((myretcode == MNG_NEEDMOREDATA) ||
- (myretcode == MNG_NEEDTIMERWAIT)) {
- if (myretcode == MNG_NEEDMOREDATA)
- /* wait for more input-data */;
- else
- /* wait for timer interval */;
-
- myretcode = mng_display_resume (myhandle);
- }
-
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-More advanced programming methods may require a different approach,
-but the final result should function as in the code above.
-
-
-.SS Displaying after reading
-
-This method is used to display a file that was previously read.
-It is primarily meant for viewers with direct file access, such as
-1a local harddisk.
-
-Once you have successfully read the file, all you need to do is:
-
- myretcode = mng_display (myhandle);
-
- while (myretcode == MNG_NEEDTIMERWAIT) {
- /* wait for timer interval */;
- myretcode = mng_display_resume (myhandle);
- }
-
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-Again, more advanced programming methods may require a different
-approach, but the final result should function as in the code above.
-
-
-.SS Display manipulation
-
-Several HLAPI functions are provided to allow a user to manipulate
-the normal flow of an animation.
-
-\- mng_display_freeze (mng_handle hHandle)
-
-This will "freeze" the animation in place.
-
-\- mng_display_resume (mng_handle hHandle)
-
-This function can be used to resume a frozen animation, or to force
-the library to advance the animation to the next frame.
-
-\- mng_display_reset (mng_handle hHandle)
-
-This function will "reset" the animation into its pristine state.
-Calling mng_display() afterwards will re-display the animation
-from the first frame.
-
-\- mng_display_golayer (mng_handle hHandle,
- mng_uint32 iLayer)
-
-\- mng_display_goframe (mng_handle hHandle,
- mng_uint32 iFrame)
-
-\- mng_display_gotime (mng_handle hHandle,
- mng_uint32 iPlaytime)
-
-These three functions can be used to "jump" to a specific layer, frame
-or timeslot in the animation. You must "freeze" the animation before
-using any of these functions.
-
-All above functions may only be called during a timer interval!
-It is the applications responsibility to cleanup any resources with
-respect to the timer wait.
-
-
-.SH VI. Writing
-
-The main focus of the library lies in its displaying capabilites.
-But it does offer writing support as well.
-You can create and write a file, or you can write a file you
-have previously read, providing the storage of chunks was enabled
-and active.
-
-For this to work you must have compiled the library with the
-MNG_WRITE_SUPPO1RT and MNG_ACCESS_CHUNKS directives. The standard DLL and
-Shared Library have this on by default!
-
-
-.SS Setup
-
-As always you must have initialized the library and be the owner of
-a mng_handle. The following callbacks are essential:
-
- mng_openstream, mng_writedata, mng_closestream
-
-You can optionally define:
-
- mng_errorproc, mng_traceproc
-
-The creation and writing functions will fail if you are in the middle
-of reading, creating or writing a file.
-
-
-.SS Creating a new file
-
-To start a new file the library must be in its initial state.
-First you need to tell the library your intentions:
-
- myretcode = mng_create (myhandle);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-After that you start adding the appropriate chunks:
-
- myretcode = mng_put1chunk_mhdr (myhandle, ...);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-And so on, and so forth. Note that the library will automatically signal
-the logical end of the file by the ending chunk. Also the first chunk
-will indicate the library the filetype (eg. PNG, JNG or MNG) and force
-the proper signature when writing the file.
-
-The code above can be simplified, as you can always get the last errorcode
-by using the mng_getlasterror() function:
-
- if ( (mng_putchunk_xxxx (myhandle, ...)) or
- (mng_putchunk_xxxx (myhandle, ...)) or
- ...etc... )
- /* process error */;
-
-Please note that you must have a pretty good understanding of the chunk
-specification. Unlike the read functions, there are virtually no checks,
-so it is quite possible to write completely wrong files.
-It is a good practice to read back your file into the library to verify
-its integrity.
-
-Once you've got all the chunks added, all you do is:
-
- myretcode mng_write (myhandle);
- if (myretcode != MNG_NOERROR)
- /* process error */;
-
-And presto. You're done. The real work is of course carried out in
-your callbacks. Note that this is a single operation as opposed to
-the read & display functions that may return with MNG_NEEDMOREDATA
-and/or MNG_NEEDTIMERWAIT. The write function just does the job, and
-only returns after it's finished or if it encounters some
-unrecoverable error.
-
-
-.SS Writing a previously read file
-
-If you have already successfully read a file, you can use the library to
-write it out as a copy or something. You MUST have compiled the library
-with the MNG_STORE_CHUNKS directive, and you must have done
-mng_set_storechunks (myhandle, MNG_TRUE).
-
-This doesn't require the MNG_ACCESS_CHUNKS directive, unless you want
-to fiddle with the chunks as well.
-
-Again all you need to do is:
-
- myretcode mng_write (myhandle);
- if (myretcode != MNG_NOERROR)
- /* process error */;

-.TH MNG 5 "July 25, 2000"
-.SH NAME
-mng \- Multiple-image Network Graphics (MNG) format
-.SH DESCRIPTION
-MNG (Multiple-image Network Graphics) is the animation extension of the
-popular PNG image-format. PNG (Portable Network Graphics) is an
-extensible file format for the lossless, portable, well-compressed
-storage of raster images.
-.br
-
-MNG has advanced animation features which make it very useful as a full
-replacement for GIF animations. These features allow animations that
-are impossible with GIF or result in much smaller files as GIF.
-
-As MNG builds on the same structure as PNG, it is robust, extensible and
-free of patents. It retains the same clever file integrity checks as in PNG.
-
-MNG also embraces the lossy JPEG image-format in a sub-format named JNG,
-which allows for alpha-transparency and color-correction on highly
-compressed (photographic) images.

- *************************************************************************
- !!!!!!!! THIS NEXT BIT IS IMPORTANT !!!!!!!!!
- *************************************************************************
-
- If you have defined MNG_FULL_CMS (and are using lcms), you will have to
- think hard about the following routines.
-
- lcms requires 2 profiles to work off the differences in the input-image
- and the output-device. The ICC profile for the input-image will be
- embedded within it to reflect its color-characteristics, but the output
- profile depends on the output-device, which is something only *YOU* know
- about. sRGB (standard RGB) is common for x86 compatible environments
- (eg. Windows, Linux and some others)
-
- If you are compiling for a sRGB compliant system you probably won't have
- to do anything special. (unless you want to of course)
-
- If you are compiling for a non-sRGB compliant system
- (eg. SGI, Mac, Next, others...)
- you *MUST* define a proper ICC profile for the generic output-device
- associated with that platform.
-
- In either event, you may also want to offer an option to your users to
- set the profile manually, or, if you know how, set it from a
- system-defined default.
-
- TO RECAP: for sRGB systems (Windows, Linux) no action required!
- for non-sRGB systems (SGI, Mac, Next) ACTION REQUIRED!
-
- Please visit http://www.srgb.com, http://www.color.org and
- http://www.littlecms.com for more info.

-************************************************************************
-
-Parts of this software have been adapted from the libpng package.
-Although this library supports all features from the PNG specification
-(as MNG descends from it) it does not require the libpng package.
-It does require the zlib library and optionally the IJG jpeg library,
-and/or the "little-cms" library by Marti Maria (depending on the
-inclusion of support for JNG and Full-Color-Management respectively.
-
-This library's function is primarily to read and display MNG
-animations. It is not meant as a full-featured image-editing
-component! It does however offer creation and editing functionality
-at the chunk level.
-(future modifications may include some more support for creation
- and or editing)
