Yes.
ImageMagick is the most common way to do this. It's a toolkit for making
all kinds of image manipulations, and it has both command line tools and
interfaces for driving it from Perl.

Imager is a newer smaller, and more directed way to do graphics in Perl.
It can't do everything ImageMagick/PerlMagick can do, but it's a bit
easier to use, and should generally run faster for similar tasks.

The books _Graphics Programming in Perl_ and _Perl Graphics Programming_
get into all of this & more.
