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.
|
|
|
|
|
|
