Improved JPEG encoder.
|
||||
mozjpeg (Mozilla JPEG Encoder Project)
|
||||
|
||||
This will not interfere with Slackware's libjpeg,
|
||||
as it installs to /opt/.
|
||||
mozjpeg is a fork of libjpeg-turbo from Mozilla Research. Its goal is to
|
||||
reduce the size of JPEG files without reducing quality or compatibility
|
||||
with the vast majority of the world's deployed decoders. The idea is to
|
||||
reduce transfer times for JPEGs on the Web, thus reducing page load times.
|
||||
|
||||
The binaries are in /opt/libmozjpeg/bin/.
|
||||
mozjpeg is not intended to be a general JPEG library replacement. It makes
|
||||
tradeoffs that are intended to benefit Web use cases and focuses solely
|
||||
on improving encoding. It is best used as part of a Web encoding workflow.
|
||||
|
||||
In essence, libjpeg-turbo (as shipped with Slackware) is optimized for
|
||||
speed of encoding/decoding, while mozjpeg is optimized for encoding
|
||||
smaller file sizes (at the expense of speed). mozjpeg will not interfere
|
||||
with Slackware's libjpeg-turbo package, as it installs to /opt/mozjpeg/.
|
||||
|
||||
mozjpeg supports multiple versions of the libjpeg API. By default,
|
||||
version 6b is built. If you need compatibility with libjpeg 7 or 8,
|
||||
set API=7 or API=8 in the script's environment.
|
||||
|
||||
Optionally, mozjpeg can be built with Java wrapper support for
|
||||
turbojpeg. To do this, install one of: jdk, openjdk, openjdk8, or
|
||||
openjdk6. Then run this script with JAVA=yes in the environment.
|
||||
|
||||
To run the binaries, it's probably easiest to add this to ~/.bash_profile:
|
||||
|
||||
export PATH=/opt/mozjpeg/bin:$PATH
|
||||
export MANPATH=/opt/mozjpeg/man:$MANPATH
|
||||
|
||||
To compile & link with the mozjpeg libraries, use -I/opt/mozjpeg/include
|
||||
and -L/opt/mozjpeg/lib (or lib64). You might also want -static, or else
|
||||
-Wl,-rpath,/opt/mozjpeg/lib (or lib64).
|
||||
|
||||
If you built with JAVA=yes, the java library will be installed
|
||||
as /opt/mozjpeg/classes/turbojpeg.jar, and the docs will be in
|
||||
/usr/doc/mozjpeg-$VERSION/javadoc.
