This directory contains an original copy of the image_size (determine image
dimensions) routine written by Jef Poskanzer.  This routine served as the
primary basis for my imagsize utility, so I'm providing a copy here as a
courtesy.  A complete copy of image_size can be found at
http://www.acme.com/software/image_size/.

There is also an original copy of the jpegdump (dump JPEG markers) routine
written by Allan Hessenflow.  This routine served as the basis for the JPEG
quality estimation routine in my imagsize utility, so I'm providing a copy here
as a courtesy.  A complete copy of jpegdump was available at the website
http://www.programmersheaven.com/zone10/cat453/17054.htm, but this link is no
longer active.

This directory contains an original copy of the pngrewrite (rewrite PNG image
files) written by Jason Summers.  This routine served as the primary basis for
my pngrecolor utility, so I'm providing a copy here as a courtesy.  A complete
copy of pngrewrite can be found at http://entropymine.com/jason/pngrewrite/.

There is also an original copy of the rdjpgcom (read and write JPEG comments)
written by Thomas Lane as part of the Independent JPEG Group's JPEG v9c
software.  This routine served as the primary basis for my jpgcom utility, so
I'm providing a copy here as a courtesy.  A complete copy of JPEG v9c can be
found at http://www.ijg.org/files/.
