The ImageMagick (http://www.imagemagick.org/) set of utilities sounds exactly like
what you are looking for.
>From the web site:
ImageMagickTM is a robust collection of tools and libraries to read, write, and
manipulate an image in many image formats (over 68 major formats) including popular
formats like TIFF, JPEG, PNG, PDF, PhotoCD, and GIF. With ImageMagick you can create
images dynamically, making it suitable for Web applications. You can also resize,
rotate, sharpen, color reduce, or add special effects to an image and save your
completed work in the same or differing image format. Image processing operations are
available from the command line, as well as through C, C++, Perl, or Java progamming
interfaces.
[*] Convert an image from one format to another (e.g. TIFF to JPEG)
[*] Resize, rotate, sharpen, color reduce, or add special effects to an image
[*] Create a montage of image thumbnails
[*] Create a transparent image suitable for use on the Web
[*] Turn a group of images into a GIF animation sequence
[*] Create a composite image by combining several separate images
[*] Draw shapes or text on an image
[*] Decorate an image with a border or frame
[*] Describe the format and characteristics of an image
I've used it in several CGI scripts, and also use it to build animated GIFs and such
for web sites. Works great!
