# jpeg/cfg - "Build" settings for package

#---------------------------------------------------------------------

[technotes]

1. The source tarball used by this package has been renamed.

#---------------------------------------------------------------------

2. This distro's "jpeg" package is based  on  "mozjpeg".  "mozjpeg" is
a drop-in  replacement  for the "jpeg-turbo" variation of "jpeg".  The
differences are as follows:

      * mozjpeg is typically 2X to 4X and up slower for compression
      * but mozjpeg compressed output is typically 5% to 15% smaller
      * and mozjpeg decompression may be noticeably faster

#---------------------------------------------------------------------

3. If the system "jpeg" core binaries and  libraries  are provided  by
"mozjpeg", the following two commands should  have  close to the  same
effect:

      jpegtran  -copy none -optimize moo.jpg > moo2.jpg
      jpegoptim -fpsP moo.jpg

Both commands will optimize "moo.jpg".  The 1st will  write the output
to "moo2.jpg" and not preserve timestamps.  The 2nd  will rewrite  the
input file  and  will preserve timestamps.  The optimization  will  be
lossless in both cases.
