The diff file for original JPEG library
---------------------------------------
There are two files in /doc directory:
- jpeg-6b-steg.diff: the original diff file used in the first version of
OutGuess.
- jpeg-6b-steg-newer.diff: the most recent diff file to make the original JPEG
library compliant with OutGuess. After this change, the JPEG was renamed in
OutGuess to jpeg-<version>-steg.
The JPEG library (without changes) is available at https://www.ijg.org/files/.
The tarball name for version 6b is jpegsrc.v6b.tar.gz (or jpegsr6b.zip).
To apply the diff used by OutGuess to original JPEG library, you must use the
patch command:
cp jpeg-6b-steg-newer.diff <original-jpeg-directory>
cd <original-jpeg-directory>
patch -p1 < jpeg-6b-steg-newer.diff
