Indeed it is.

The 'mogrify' utility can perform a number of programmatic transforms on
images, including type conversions, rescaling, rotation, cropping,
antialiasing, blurring (and a number of other image effects).  It's a
command line utility, and a very convenient way for applying standard
(or repetitive) conversions to large numbers of images.

Most GNU/Linux distributions, in particular Debian, make compatibility
of software to systems issues far more trivial than proprietary Unices
or legacy MS Windows.  The general alternative is to build and install
yourself from sources.

Works for me under Debian/Woody and Debian/Sid.
