looking for a free, command line image editing application

[Cerb]

I'm looking for a free, windows command line bitmap image editing program. If it can open an image, set certain pixels to certain colors, then save, that'll be enough. Use of a text file for the operations would be acceptable (in fact, preferable).

mageMagickTM 6.1.3 is a robust collection of tools and libraries to read, write, and manipulate an image in many image formats (over 90 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 or image sequence and save your completed work in the same or differing image format. Image processing operations are available from the command line, or from the C, C++, Perl, Java, PHP, Python, or Ruby programming languages. A high-quality 2D renderer is included, which provides a subset of SVG capabilities. ImageMagick's focus is on performance, minimizing bugs, and providing stable APIs and ABIs.

I would have replied sooner, but I blew my OS up.
Imagemagick works great. Thanks!
(I would have voted a higher user rating, but it's at 6.66, so I thought, I better not mess it up ).
