mozjpeg (Mozilla JPEG Encoder Project)
|
||||
|
||||
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.

|

|
||||
|
||||
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/.

|
||||
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.
|
||||
Usage
|
||||
-----
|
||||
To run the binaries, either call them by their full paths, e.g:
|
||||
|
||||
To run the binaries, it's probably easiest to add this to ~/.bash_profile:
|
||||
$ /opt/mozjpeg/bin/cjpeg
|
||||
|
||||
export PATH=/opt/mozjpeg/bin:$PATH
|
||||
export MANPATH=/opt/mozjpeg/man:$MANPATH
|
||||
...or else:
|
||||
|
||||
$ source /etc/profile.d/mozjpeg.sh
|
||||
|
||||
...to temporarily make mozjpeg the default, in the current shell.
|
||||
Running e.g. "cjpeg" will now run the mozjpeg one. If you wanted to
|
||||
do this permanently for all users (not recommended), you could:
|
||||
|
||||
# chmod +x /etc/profile.d/mozjpeg.sh
|
||||
|
||||
...then log out and back in. The profile script isn't executable by
|
||||
default, to avoid surprises.
|
||||
|
||||
Development
|
||||
-----------
|
||||
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). Starting with version 3.2,
|
||||
there's also pkg-config support for mozjpeg. In ~/.bash_profile:
|
||||
there's also pkg-config support for mozjpeg. If you source the profile
|
||||
script, software that uses pkg-config should find and link with the
|
||||
mozjpeg libraries automatically.
|
||||
|
||||
export PKG_CONFIG_PATH=/opt/mozjpeg/lib64/pkgconfig:$PKG_CONFIG_PATH
|
||||
|
||||
(chage lib64 to lib, for 32-bit Slackware)
|
||||
|
||||
If you built with JAVA=yes, the java library will be installed
|
||||
Java Support
|
||||
------------
|
||||
Optionally, mozjpeg can be built with Java wrapper support
|
||||
for turbojpeg. To do this, install one of: jdk, openjdk8,
|
||||
openjdk7, or openjdk6 (or possibly one of the zulu-openjdk*
|
||||
or adoptopenjdk* packages; untested). Then run this script with
|
||||
JAVA=yes in the environment. The Java library will be installed
|
||||
as /opt/mozjpeg/classes/turbojpeg.jar, and the docs will be in
|
||||
/usr/doc/mozjpeg-$VERSION/javadoc.
