Hmmmn... no manpage. Thanks, Apple.

You might also want to check out ImageMagick 
<http://www.imagemagick.org/> - as well as file-format conversions it 
allows resizing of images, and it's "mogrify" function includes "image 
scaling, image rotation, color reduction, and others". "Composite 
composites images to create new images." It also has it's own scripting 
language, apparently, and some Perl modules.

You can install ImageMagick by going to 
<ftp://ftp.imagemagick.org/pub/ImageMagick/binaries> and downloading 
ImageMagick-powerpc-apple-darwin7.2.0.tar.gz. Once you've unzipped it 
you seem to need to move or copy the resulting folder to 
/ImageMagick-5.5.7/, as the executables seem to have their full path 
hardcoded in. It seems to work on Panther.

HTH,

Stroller.
