Jp2 batch converter

Revision as of 00:33, 21 February 2008

Description

The jp2 files used by the Secondlife client, are actually j2k files. These can be encoded by image_to_j2k from openjpeg. The script checks for available tif-files in a root directory, and compresses those to j2k and renames them...

Usage

• Install OpenJPEG svn (if you have trouble compiling, you could try the binaries on their site)

svn co http://www.openjpeg.org/svn/trunk
cd trunk
mkdir bin
cd bin
cmake .. -DBUILD_EXAMPLES:BOOL=ON
make
make install

• Make sure that the binaries image_to_j2k and j2k_to_image can be executed from anywhere

• Put the code in a file named jpg2jp2.pl, and copy it to the directory where your jpg's are. Call the script:

perl jpg2jp2.pl
