JPEG, the Independent JPEG Group's JPEG software

Release date: 
Thursday, 29 March, 2018



Authors/Port authors:

Port of jpeg library that implements JPEG image compression and decompression and that is used by some XFree86/OS2 programs.

This software is distributed in two modes:
  • as compressed package that you have to download and manually install; if prerequisites are required, you will have to manually install them too;
  • as RPM package; you can install it using your favorite rpm package manager, that will take care to download and install both the software and its prerequisites.
Choose the installation mode that you prefer. Please note that not all the versions are available in both the installation modes.

Installation with rpm

This program is installable using the rpm package manager. See below for the install string. Required prerequisites are automatically processed by the package manager and, if needed, downloaded and installed.

Jpeg library v. 9d (6/8/2020, Mikulas Patocka) Readme/What's new
CHANGE LOG for Independent JPEG Group's JPEG software Version 9d 12-Jan-2020 ----------------------- Optimize the optimal Huffman code table generation to produce slightly smaller files. Thank to John Korejwa for suggestion. Note: Requires rebuild of testimgp.jpg. Decoding Huffman: Use default tables if tables are not defined. Thank to Simone Azzalin for report (Motion JPEG), and to Martin Strunz for hint. Add sanity check in optimal Huffman code table generation. Thank to Adam Farley for suggestion. rdtarga.c: use read_byte(), with EOF check, instead of getc() in read_*_pixel(). Thank to Chijin Zhou for cjpeg potential vulnerability report. jmemnobs.c: respect the max_memory_to_use setting in jpeg_mem_available() computation. Thank to Sheng Shu and Dongdong She for djpeg potential vulnerability report. jdarith.c, jdhuff.c: avoid left shift of negative value compiler warning in decode_mcu_AC_refine(). Thank to Indu Bhagat for suggestion. Add x64 (64-bit) platform support, avoid compiler warnings. Thank to Jonathan Potter, Feiyun Wang, and Sheng Shu for suggestion. Adjust libjpeg version specification for pkg-config file. Thank to Chen Chen for suggestion. Restore GIF read and write support from libjpeg version 6a. Thank to Wolfgang Werner (W.W.) Heinz for suggestion. Improve consistency in raw (downsampled) image data processing mode. Thank to Zhongyuan Zhou for hint. Avoid out of bounds array read (AC derived table pointers) in start pass in jdhuff.c. Thank to Peng Li for report. Improve code sanity (jdhuff.c). Thank to Reza Mirzazade farkhani for reports. Add jpegtran -drop option; add options to the crop extension and wipe to fill the extra area with content from the source image region, instead of gray out.
Jpeg library v. 9c (29/3/2018, Mikulas Patocka) Readme/What's new
CHANGE LOG for Independent JPEG Group's JPEG software Version 9c 14-Jan-2018 ----------------------- jpegtran: add an option to the -wipe switch to fill the region with the average of adjacent blocks, instead of gray out. Thank to Caitlyn Feddock and Maddie Ziegler for inspiration. Make range extension bits adjustable (in jpegint.h). Thank to Robin Watts for suggestion. Provide macros for fflush() and ferror() in jinclude.h in order to facilitate adaption by applications using an own FILE class. Thank to Gerhard Huber for suggestion. Add libjpeg pkg-config file. Thank to Mark Lavi, Vincent Torri, Patrick McMunn, and Huw Davies for suggestion. Add sanity checks in cjpeg image reader modules. Thank to Bingchang, Liu for reports.
