I have a fun/cool script in mind that involves images.
In order for it to work, I need to be able to look at various file formats (mostly jpg, gif, sometimes png, and the very occasional tiff).
I think I can handle that much relatively easily - images usally lead to either GD or ImageMagick - or some spinoff thereon.

What I specifically am curious about is analysis of the image. I want to look at an image and determine what % of the image is a specific color (well, actually what % is within a specific range of colors).
As I understand it (from a 10billion foot view) - I will need to open XYZ file, regardless of its type, and convert it to a bitmap (in memory) - the bitmap is then an array that has the color information for each pixel of that image. I can then just iterate that array and look at that color info and if it matches my desires, do whatever floats my boat (likely increment a counter).

So the end result I can open 10 files and see that file ABC has more of the color I want than file XYZ does, and I can sort them out that way.

Is that generally how one can think of images? Or am I missing massive steps?
If that is the general process - which modules allow me to look at a bitmap at that level?
A quick CPAN search would seem to indicate Image::Info::BMP - but glancing over that doesn't really leng much information.

Any suggestions from ye fine monks?
