%general-entities; ]> $LastChangedBy$ $Date$ The libjpeg package contains libraries that allow compression of image files based on the Joint Photographic Experts Group standard. It is a "lossy" compression algorithm. Download (HTTP): Download (FTP): Download size: &libjpeg-size; Estimated disk space required: &libjpeg-buildsize; Estimated build time: &libjpeg-time; Install libjpeg by running the following commands: ./configure --prefix=/usr --enable-static --enable-shared && make && make install --enable-static --enable-shared: These switches tell libjpeg to build both shared and static libraries. The libjpeg package contains cjpeg, djpeg, jpegtran, rdjpgcom, wrjpgcom and libjpeg libraries. cjpeg compresses image files to produce a JPEG/JFIF file on the standard output. Currently supported input file formats are: PPM (PBMPLUS color format), PGM (PBMPLUS gray-scale format), BMP, and Targa. djpeg decompresses image files from JPEG/JFIF format to either PPM (PBMPLUS color format), PGM (PBMPLUS gray-scale format), BMP, or Targa format. jpegtran is used for lossless transformation of JPEG files. rdjpgcom displays text comments from within a JPEG file. wrjpgcom inserts text comments into a JPEG file. These libraries are used by many programs for reading and writing jpeg format files.
