Hello!

I would like to write programs which can process / work-with pictures, but I never did such stuff before. (I use FPC 1.0.4 on LINUX.) What I want to do at the beginning is reading in a JPG or other file and then have it available in memory in a usable format. In a second step, I want to write this picture back to a file, mostly in jpg.
In a 3rd step, I want to add procedures/functions to modify the picture in memory and comparing two images against each other to find out the differences (i.e. for a motion detection) or to find out that two pictures with different names have the same content.

Because I am very sure that there exist some ready made libraries/units for that, I please you to tell me which ones are EASY to use and (so I hope) usable in OOP programming style (I do not use Delphi style).
