-IJG JPEG LIBRARY: FILE LIST
-
-Copyright (C) 1994-1998, Thomas G. Lane.
-This file is part of the Independent JPEG Group's software.
-For conditions of distribution and use, see the accompanying README file.
-
-
-Here is a road map to the files in the IJG JPEG distribution. The
-distribution includes the JPEG library proper, plus two application
-programs ("cjpeg" and "djpeg") which use the library to convert JPEG
-files to and from some other popular image formats. A third application
-"jpegtran" uses the library to do lossless conversion between different
-variants of JPEG. There are also two stand-alone applications,
-"rdjpgcom" and "wrjpgcom".
-
-
-THE JPEG LIBRARY
-================
-
-Include files:
-
-jpeglib.h JPEG library's exported data and function declarations.
-jconfig.h Configuration declarations. Note: this file is not present
- in the distribution; it is generated during installation.
-jmorecfg.h Additional configuration declarations; need not be changed
- for a standard installation.
-jerror.h Declares JPEG library's error and trace message codes.
-jinclude.h Central include file used by all IJG .c files to reference
- system include files.
-jpegint.h JPEG library's internal data structures.
-jchuff.h Private declarations for Huffman encoder modules.
-jdhuff.h Private declarations for Huffman decoder modules.
-jdct.h Private declarations for forward & reverse DCT subsystems.
-jmemsys.h Private declarations for memory management subsystem.
-jversion.h Version information.
-
-Applications using the library should include jpeglib.h (which in turn
-includes jconfig.h and jmorecfg.h). Optionally, jerror.h may be included
-if the application needs to reference individual JPEG error codes. The
-other include files are intended for internal use and would not normally
-be included by an application program. (cjpeg/djpeg/etc do use jinclude.h,
-since its function is to improve portability of the whole IJG distribution.
-Most other applications will directly include the system include files they
-want, and hence won't need jinclude.h.)
-
-
-C source code files:
-
-These files contain most of the functions intended to be called directly by
-an application program:
-
-jcapimin.c Application program interface: core routines for compression.
-jcapistd.c Application program interface: standard compression.
-jdapimin.c Application program interface: core routines for decompression.
-jdapistd.c Application program interface: standard decompression.
-jcomapi.c Application program interface routines common to compression
- and decompression.
-jcparam.c Compression parameter setting helper routines.
-jctrans.c API and library routines for transcoding compression.
-jdtrans.c API and library routines for transcoding decompression.
-
-Compression side of the library:
-
-jcinit.c Initialization: determines which other modules to use.
-jcmaster.c Master control: setup and inter-pass sequencing logic.
-jcmainct.c Main buffer controller (preprocessor => JPEG compressor).
-jcprepct.c Preprocessor buffer controller.
-jccoefct.c Buffer controller for DCT coefficient buffer.
-jccolor.c Color space conversion.
-jcsample.c Downsampling.
-jcdctmgr.c DCT manager (DCT implementation selection & control).
-jfdctint.c Forward DCT using slow-but-accurate integer method.
-jfdctfst.c Forward DCT using faster, less accurate integer method.
-jfdctflt.c Forward DCT using floating-point arithmetic.
-jchuff.c Huffman entropy coding for sequential JPEG.
-jcphuff.c Huffman entropy coding for progressive JPEG.
-jcmarker.c JPEG marker writing.
-jdatadst.c Data destination manager for stdio output.
-
-Decompression side of the library:
-
-jdmaster.c Master control: determines which other modules to use.
-jdinput.c Input controller: controls input processing modules.
-jdmainct.c Main buffer controller (JPEG decompressor => postprocessor).
-jdcoefct.c Buffer controller for DCT coefficient buffer.
-jdpostct.c Postprocessor buffer controller.
-jdmarker.c JPEG marker reading.
-jdhuff.c Huffman entropy decoding for sequential JPEG.
-jdphuff.c Huffman entropy decoding for progressive JPEG.
-jddctmgr.c IDCT manager (IDCT implementation selection & control).
-jidctint.c Inverse DCT using slow-but-accurate integer method.
-jidctfst.c Inverse DCT using faster, less accurate integer method.
-jidctflt.c Inverse DCT using floating-point arithmetic.
-jidctred.c Inverse DCTs with reduced-size outputs.
-jdsample.c Upsampling.
-jdcolor.c Color space conversion.
-jdmerge.c Merged upsampling/color conversion (faster, lower quality).
-jquant1.c One-pass color quantization using a fixed-spacing colormap.
-jquant2.c Two-pass color quantization using a custom-generated colormap.
- Also handles one-pass quantization to an externally given map.
-jdatasrc.c Data source manager for stdio input.
-
-Support files for both compression and decompression:
-
-jerror.c Standard error handling routines (application replaceable).
-jmemmgr.c System-independent (more or less) memory management code.
-jutils.c Miscellaneous utility routines.
-
-jmemmgr.c relies on a system-dependent memory management module. The IJG
-distribution includes the following implementations of the system-dependent
-module:
-
-jmemnobs.c "No backing store": assumes adequate virtual memory exists.
-jmemansi.c Makes temporary files with ANSI-standard routine tmpfile().
-jmemname.c Makes temporary files with program-generated file names.
-jmemdos.c Custom implementation for MS-DOS (16-bit environment only):
- can use extended and expanded memory as well as temp files.
-jmemmac.c Custom implementation for Apple Macintosh.
-
-Exactly one of the system-dependent modules should be configured into an
-installed JPEG library (see install.doc for hints about which one to use).
-On unusual systems you may find it worthwhile to make a special
-system-dependent memory manager.
-
-
-Non-C source code files:
-
-jmemdosa.asm 80x86 assembly code support for jmemdos.c; used only in
- MS-DOS-specific configurations of the JPEG library.
-
-
-CJPEG/DJPEG/JPEGTRAN
-====================
-
-Include files:
-
-cdjpeg.h Declarations shared by cjpeg/djpeg/jpegtran modules.
-cderror.h Additional error and trace message codes for cjpeg et al.

-
-C source code files:
-
-cjpeg.c Main program for cjpeg.
-djpeg.c Main program for djpeg.
-jpegtran.c Main program for jpegtran.
-cdjpeg.c Utility routines used by all three programs.
-rdcolmap.c Code to read a colormap file for djpeg's "-map" switch.
-rdswitch.c Code to process some of cjpeg's more complex switches.

-rdtarga.c Targa file input.
-
-Image file writer modules for djpeg:
-
-wrbmp.c BMP file output.
-wrgif.c GIF file output (a mere shadow of its former self).
-wrppm.c PPM/PGM file output.
-wrrle.c Utah RLE file output.

-
-C source code files:
-
