Lane. 5 | It was modified by The libjpeg-turbo Project to include only information 6 | relevant to libjpeg-turbo. 7 | For conditions of distribution and use, see the accompanying README.ijg file. 8 | 9 | 10 | Since numerous people will be contributing code and bug fixes, it's important 11 | to establish a common coding style. The goal of using similar coding styles 12 | is much more important than the details of just what that style is. 13 | 14 | In general we follow the recommendations of "Recommended C Style and Coding 15 | Standards" revision 6.1 (Cannon et al. as modified by Spencer, Keppel and 16 | Brader). This document is available in the IJG FTP archive (see 17 | jpeg/doc/cstyle.ms.tbl.Z, or cstyle.txt.Z for those without nroff/tbl). 18 | 19 | Block comments should be laid out thusly: 20 | 21 | /* 22 | * Block comments in this style. 23 | */ 24 | 25 | We indent statements in K&R style, e.g., 26 | if (test) { 27 | then-part; 28 | } else { 29 | else-part; 30 | } 31 | with two spaces per indentation level. (This indentation convention is 32 | handled automatically by GNU Emacs and many other text editors.) 33 | 34 | Multi-word names should be written in lower case with underscores, e.g., 35 | multi_word_name (not multiWordName). Preprocessor symbols and enum constants 36 | are similar but upper case (MULTI_WORD_NAME). Names should be unique within 37 | the first fifteen characters. 38 | 39 | Note that each function definition must begin with GLOBAL(type), LOCAL(type), 40 | or METHODDEF(type). These macros expand to "static type" or just "type" as 41 | appropriate. They provide a readable indication of the routine's usage and 42 | can readily be changed for special needs. (For instance, special linkage 43 | keywords can be inserted for use in Windows DLLs.) 44 | 45 | A similar solution is used for external function declarations (see the EXTERN 46 | macro.) 47 | 48 | 49 | The JPEG library is intended to be used within larger programs. Furthermore, 50 | we want it to be reentrant so that it can be used by applications that process 51 | multiple images concurrently. The following rules support these requirements: 52 | 53 | 1. Avoid direct use of file I/O, "malloc", error report printouts, etc; 54 | pass these through the common routines provided. 55 | 56 | 2. Minimize global namespace pollution. Functions should be declared static 57 | wherever possible. (Note that our method-based calling conventions help this 58 | a lot: in many modules only the initialization function will ever need to be 59 | called directly, so only that function need be externally visible.) All 60 | global function names should begin with "jpeg_". 61 | 62 | 3. Don't use global variables; anything that must be used in another module 63 | should be in the common data structures. 64 | 65 | 4. Don't use static variables except for read-only constant tables. Variables 66 | that should be private to a module can be placed into private structures (see 67 | the system architecture document, structure.txt). 68 | 69 | 5. Source file names should begin with "j" for files that are part of the 70 | library proper; source files that are not part of the library, such as cjpeg.c 71 | and djpeg.c, do not begin with "j". Keep compression and decompression code in 72 | separate source files --- some applications may want only one half of the 73 | library. 74 | 75 | Note: these rules (particularly #4) are not followed religiously in the 76 | modules that are used in cjpeg/djpeg but are not part of the JPEG library 77 | proper. Those modules are not really intended to be used in other 78 | applications. 79 | -------------------------------------------------------------------------------- /croptest.in: -------------------------------------------------------------------------------- 1 | #!/bin/bash 2 | 3 | set -u 4 | set -e 5 | trap onexit INT 6 | trap onexit TERM 7 | trap onexit EXIT 8 | 9 | onexit() 10 | { 11 | if [ -d $OUTDIR ]; then 12 | rm -rf $OUTDIR 13 | fi 14 | } 15 | 16 | runme() 17 | { 18 | echo \*\*\* $* 19 | $* 20 | } 21 | 22 | IMAGE=vgl_6548_0026a.bmp 23 | WIDTH=128 24 | HEIGHT=95 25 | IMGDIR=@CMAKE_CURRENT_SOURCE_DIR@/testimages 26 | OUTDIR=`mktemp -d /tmp/__croptest_output.XXXXXX` 27 | EXEDIR=@CMAKE_CURRENT_BINARY_DIR@ 28 | 29 | if [ -d $OUTDIR ]; then 30 | rm -rf $OUTDIR 31 | fi 32 | mkdir -p $OUTDIR 33 | 34 | exec >$EXEDIR/croptest.log 35 | 36 | echo "============================================================" 37 | echo "$IMAGE ($WIDTH x $HEIGHT)" 38 | echo "============================================================" 39 | echo 40 | 41 | for PROGARG in "" -progressive; do 42 | 43 | cp $IMGDIR/$IMAGE $OUTDIR 44 | basename=`basename $IMAGE .bmp` 45 | echo "------------------------------------------------------------" 46 | echo "Generating test images" 47 | echo "------------------------------------------------------------" 48 | echo 49 | runme $EXEDIR/cjpeg $PROGARG -grayscale -outfile $OUTDIR/${basename}_GRAY.jpg $IMGDIR/${basename}.bmp 50 | runme $EXEDIR/cjpeg $PROGARG -sample 2x2 -outfile $OUTDIR/${basename}_420.jpg $IMGDIR/${basename}.bmp 51 | runme $EXEDIR/cjpeg $PROGARG -sample 2x1 -outfile $OUTDIR/${basename}_422.jpg $IMGDIR/${basename}.bmp 52 | runme $EXEDIR/cjpeg $PROGARG -sample 1x2 -outfile $OUTDIR/${basename}_440.jpg $IMGDIR/${basename}.bmp 53 | runme $EXEDIR/cjpeg $PROGARG -sample 1x1 -outfile $OUTDIR/${basename}_444.jpg $IMGDIR/${basename}.bmp 54 | echo 55 | 56 | for NSARG in "" -nosmooth; do 57 | 58 | for COLORSARG in "" "-colors 256 -dither none -onepass"; do 59 | 60 | for Y in {0..16}; do 61 | 62 | for H in {1..16}; do 63 | 64 | X=$(( (Y*16)%128 )) 65 | W=$(( WIDTH-X-7 )) 66 | if [ $Y -le 15 ]; then 67 | CROPSPEC="${W}x${H}+${X}+${Y}" 68 | else 69 | Y2=$(( HEIGHT-H )); 70 | CROPSPEC="${W}x${H}+${X}+${Y2}" 71 | fi 72 | 73 | echo "------------------------------------------------------------" 74 | echo $PROGARG $NSARG $COLORSARG -crop $CROPSPEC 75 | echo "------------------------------------------------------------" 76 | echo 77 | for samp in GRAY 420 422 440 444; do 78 | $EXEDIR/djpeg $NSARG $COLORSARG -rgb -outfile $OUTDIR/${basename}_${samp}_full.ppm $OUTDIR/${basename}_${samp}.jpg 79 | convert -crop $CROPSPEC $OUTDIR/${basename}_${samp}_full.ppm $OUTDIR/${basename}_${samp}_ref.ppm 80 | runme $EXEDIR/djpeg $NSARG $COLORSARG -crop $CROPSPEC -rgb -outfile $OUTDIR/${basename}_${samp}.ppm $OUTDIR/${basename}_${samp}.jpg 81 | runme cmp $OUTDIR/${basename}_${samp}.ppm $OUTDIR/${basename}_${samp}_ref.ppm 82 | done 83 | echo 84 | 85 | done 86 | 87 | done 88 | 89 | done 90 | 91 | done 92 | 93 | done 94 | 95 | echo SUCCESS! 96 | -------------------------------------------------------------------------------- /doc/html/bc_s.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/winlibs/libjpeg/1177955a8eecc6cdc61a39e59081e410d9054f66/doc/html/bc_s.png -------------------------------------------------------------------------------- /doc/html/bc_sd.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/winlibs/libjpeg/1177955a8eecc6cdc61a39e59081e410d9054f66/doc/html/bc_sd.png -------------------------------------------------------------------------------- /doc/html/classes.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | TurboJPEG: Data Structure Index 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 |

The Java front end for this is defined in several classes 7 | located under org/libjpegturbo/turbojpeg. The source code for these Java 8 | classes is licensed under a BSD-style license, so the files can be incorporated 9 | directly into both open source and proprietary projects without restriction. A 10 | Java archive (JAR) file containing these classes is also shipped with the 11 | "official" distribution packages of libjpeg-turbo. 12 | 13 | TJExample.java, which should also be located in the same directory as this 14 | README file, demonstrates how to use the TurboJPEG Java API to compress and 15 | decompress JPEG images in memory. 16 | 17 | 18 | Performance Pitfalls 19 | -------------------- 20 | 21 | The TurboJPEG Java API defines several convenience methods that can allocate 22 | image buffers or instantiate classes to hold the result of compress, 23 | decompress, or transform operations. However, if you use these methods, then 24 | be mindful of the amount of new data you are creating on the heap. It may be 25 | necessary to manually invoke the garbage collector to prevent heap exhaustion 26 | or to prevent performance degradation. Background garbage collection can kill 27 | performance, particularly in a multi-threaded environment (Java pauses all 28 | threads when the GC runs.) 29 | 30 | The TurboJPEG Java API always gives you the option of pre-allocating your own 31 | source and destination buffers, which allows you to re-use those buffers for 32 | compressing/decompressing multiple images. If the image sequence you are 33 | compressing or decompressing consists of images of the same size, then 34 | pre-allocating the buffers is recommended. 35 | 36 | 37 | Installation Directory 38 | ---------------------- 39 | 40 | The TurboJPEG Java Wrapper will look for the TurboJPEG JNI library 41 | (libturbojpeg.so, libturbojpeg.dylib, or turbojpeg.dll) in the system library 42 | paths or in any paths specified in LD_LIBRARY_PATH (Un*x), DYLD_LIBRARY_PATH 43 | (Mac), or PATH (Windows.) Failing this, on Un*x and Mac systems, the wrapper 44 | will look for the JNI library under the library directory configured when 45 | libjpeg-turbo was built. If that library directory is 46 | /opt/libjpeg-turbo/lib32, then /opt/libjpeg-turbo/lib64 is also searched, and 47 | vice versa. 48 | 49 | If you installed the JNI library into another directory, then you will need 50 | to pass an argument of -Djava.library.path={path_to_JNI_library} to java, or 51 | manipulate LD_LIBRARY_PATH, DYLD_LIBRARY_PATH, or PATH to include the directory 52 | containing the JNI library. 53 | -------------------------------------------------------------------------------- /java/doc/allclasses.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | All Classes 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 17 | 18 | 19 | 20 | 21 |

This lets you add 25 | annotations, titles, index terms, etc to your JPEG files, and later retrieve 26 | them as text. COM blocks do not interfere with the image stored in the JPEG 27 | file. The maximum size of a COM block is 64K, but you can have as many of 28 | them as you like in one JPEG file. 29 | .SH OPTIONS 30 | .TP 31 | .B \-raw 32 | Normally 33 | .B rdjpgcom 34 | escapes non-printable characters in comments, for security reasons. 35 | This option avoids that. 36 | .PP 37 | .B \-verbose 38 | Causes 39 | .B rdjpgcom 40 | to also display the JPEG image dimensions. 41 | .PP 42 | Switch names may be abbreviated, and are not case sensitive. 43 | .SH HINTS 44 | .B rdjpgcom 45 | does not depend on the IJG JPEG library. Its source code is intended as an 46 | illustration of the minimum amount of code required to parse a JPEG file 47 | header correctly. 48 | .PP 49 | In 50 | .B \-verbose 51 | mode, 52 | .B rdjpgcom 53 | will also attempt to print the contents of any "APP12" markers as text. 54 | Some digital cameras produce APP12 markers containing useful textual 55 | information. If you like, you can modify the source code to print 56 | other APPn marker types as well. 57 | .SH SEE ALSO 58 | .BR cjpeg (1), 59 | .BR djpeg (1), 60 | .BR jpegtran (1), 61 | .BR wrjpgcom (1) 62 | .SH AUTHOR 63 | Independent JPEG Group 64 | -------------------------------------------------------------------------------- /release/Config.cmake.in: -------------------------------------------------------------------------------- 1 | @PACKAGE_INIT@ 2 | 3 | include("${CMAKE_CURRENT_LIST_DIR}/@CMAKE_PROJECT_NAME@Targets.cmake") 4 | check_required_components("@CMAKE_PROJECT_NAME@") 5 | -------------------------------------------------------------------------------- /release/Distribution.xml.in: -------------------------------------------------------------------------------- 1 | 2 | 3 | @CMAKE_PROJECT_NAME@ 4 | 5 | 6 | 7 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | @PKGNAME@.pkg 24 | 25 | -------------------------------------------------------------------------------- /release/License.rtf: -------------------------------------------------------------------------------- 1 | {\rtf1\ansi\ansicpg1252\cocoartf1038\cocoasubrtf350 2 | {\fonttbl\f0\fswiss\fcharset0 Helvetica;} 3 | {\colortbl;\red255\green255\blue255;} 4 | {\*\listtable{\list\listtemplateid1\listhybrid{\listlevel\levelnfc23\levelnfcn23\leveljc0\leveljcn0\levelfollow0\levelstartat1\levelspace360\levelindent0{\*\levelmarker \{disc\}}{\leveltext\leveltemplateid1\'01\uc0\u8226 ;}{\levelnumbers;}\fi-360\li720\lin720 }{\listname ;}\listid1}} 5 | {\*\listoverridetable{\listoverride\listid1\listoverridecount0\ls1}} 6 | \margl1440\margr1440\vieww9820\viewh8480\viewkind0 7 | \deftab720 8 | \pard\pardeftab720 9 | 10 | \f0\fs24 \cf0 Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met:\ 11 | \ 12 | \pard\tx220\tx720\pardeftab720\li720\fi-720 13 | \ls1\ilvl0\cf0 {\listtext \'95 }Redistributions of source code must retain the above copyright notice, this list of conditions and the following disclaimer.\ 14 | {\listtext \'95 }Redistributions in binary form must reproduce the above copyright notice, this list of conditions and the following disclaimer in the documentation and/or other materials provided with the distribution.\ 15 | {\listtext \'95 }Neither the name of the libjpeg-turbo Project nor the names of its contributors may be used to endorse or promote products derived from this software without specific prior written permission.\ 16 | \pard\pardeftab720\qc 17 | \cf0 \ 18 | \pard\pardeftab720 19 | \cf0 THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS", AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE DISCLAIMED.

These are photographic images chosen to come from a wide variety of sources and each one picked to stress different aspects of algorithms. Images are available in 8-bit, 16-bit and 16-bit linear variations, RGB and gray. 10 | 11 | Images are available without any prohibitive copyright restrictions. 12 | 13 | These images are (c) there respective owners.

A comment block is 24 | added to the file. 25 | .PP 26 | The JPEG standard allows "comment" (COM) blocks to occur within a JPEG file. 27 | Although the standard doesn't actually define what COM blocks are for, they 28 | are widely used to hold user-supplied text strings. This lets you add 29 | annotations, titles, index terms, etc to your JPEG files, and later retrieve 30 | them as text. COM blocks do not interfere with the image stored in the JPEG 31 | file. The maximum size of a COM block is 64K, but you can have as many of 32 | them as you like in one JPEG file. 33 | .PP 34 | .B wrjpgcom 35 | adds a COM block, containing text you provide, to a JPEG file. 36 | Ordinarily, the COM block is added after any existing COM blocks; but you 37 | can delete the old COM blocks if you wish. 38 | .SH OPTIONS 39 | Switch names may be abbreviated, and are not case sensitive. 40 | .TP 41 | .B \-replace 42 | Delete any existing COM blocks from the file. 43 | .TP 44 | .BI \-comment " text" 45 | Supply text for new COM block on command line. 46 | .TP 47 | .BI \-cfile " name" 48 | Read text for new COM block from named file. 49 | .PP 50 | If you have only one line of comment text to add, you can provide it on the 51 | command line with 52 | .BR \-comment . 53 | The comment text must be surrounded with quotes so that it is treated as a 54 | single argument. Longer comments can be read from a text file. 55 | .PP 56 | If you give neither 57 | .B \-comment 58 | nor 59 | .BR \-cfile, 60 | then 61 | .B wrjpgcom 62 | will read the comment text from standard input. (In this case an input image 63 | file name MUST be supplied, so that the source JPEG file comes from somewhere 64 | else.) You can enter multiple lines, up to 64KB worth. Type an end-of-file 65 | indicator (usually control-D) to terminate the comment text entry. 66 | .PP 67 | .B wrjpgcom 68 | will not add a COM block if the provided comment string is empty. Therefore 69 | \fB\-replace \-comment ""\fR can be used to delete all COM blocks from a file. 70 | .SH EXAMPLES 71 | .LP 72 | Add a short comment to in.jpg, producing out.jpg: 73 | .IP 74 | .B wrjpgcom \-c 75 | \fI"View of my back yard" in.jpg 76 | .B > 77 | .I out.jpg 78 | .PP 79 | Attach a long comment previously stored in comment.txt: 80 | .IP 81 | .B wrjpgcom 82 | .I in.jpg 83 | .B < 84 | .I comment.txt 85 | .B > 86 | .I out.jpg 87 | .PP 88 | or equivalently 89 | .IP 90 | .B wrjpgcom 91 | .B -cfile 92 | .I comment.txt 93 | .B < 94 | .I in.jpg 95 | .B > 96 | .I out.jpg 97 | .SH SEE ALSO 98 | .BR cjpeg (1), 99 | .BR djpeg (1), 100 | .BR jpegtran (1), 101 | .BR rdjpgcom (1) 102 | .SH AUTHOR 103 | Independent JPEG Group 104 | --------------------------------------------------------------------------------
