Hello
I want to know, how to load a png image with freepascal ?
There is a png libpng package shipped with FreePascal, but I cannot find
any examples or docs.
Pascal unit Libpng is just a wrapper that calls functions from libpng.so. Documentation for libpng is available at the official page of libpng, http://www.libpng.org, you will most likely be interested in this document:
http://www.libpng.org/pub/png/libpng-1.2.5-manual.html
Or are there any onther simple image formats that can be loaded into a freepascal program ?
Well, everything can be loaded into a Pascal program...
The simplest possible image format is ppm (it is just a small header + array of RGB values for each pixel) - if you are on UNIX-like system and have installed proper documentation then
man ppm
should give you a simple specification of ppm format. You may also take a look at it's cousins, pbm, pgm and the most general one, pnm.
Regards, Michalis
