Introduction to Libjpeg

Libjpeg is a library developed by the Independent JPEG Group for JPEG image compression.

Project Homepage: http://www.ijg.org/

Dependencies

Non-Multilib

Compile the package: 

./configure --prefix=/usr --enable-static --enable-shared &&
make

Install the package 

make install

Command Explanations

--enable-static --enable-shared: These switches tell libjpeg to build both shared and static libraries.

Multilib

32Bit

Compile the package: 

CC="gcc ${BUILD32}" ./configure --prefix=/usr --enable-static --enable-shared &&
make

Install the package 

make install

N32

Compile the package: 

CC="gcc ${BUILDN32}" ./configure --prefix=/usr --libdir=/usr/lib32 \
    --enable-static --enable-shared &&
make libdir=/usr/lib32

Install the package 

make libdir=/usr/lib32 install

64Bit

Compile the package: 

CC="gcc ${BUILD64}" ./configure --prefix=/usr --libdir=/usr/lib64 \
    --enable-static --enable-shared &&
make libdir=/usr/lib64

Install the package 

make libdir=/usr/lib64 install

Contents

Installed Programs: cjpeg, djpeg, jpegtran, rdjpgcom, and wrjpgcom
Installed Libraries: libjpeg.{a,la,so}
Installed Directories: None

Short Descriptions

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.
libjpeg.{so,a} library is used by many programs for reading and writing JPEG format files.
