I installed gpc and all required or recommended packages using aptitude. The manual apparently contains no mention of graphics output. But that's why I downloaded Pascal in the first place!
Looking through the mailing list archives, I find mention of a GRX library. But when I do a search for "grx" within aptitude, I come up empty.
You can download GRX from http://grx.gnu.de. You have to compile it before you can use it and for compilation you should choose X version (other variants are useless for you).
All I want to do is create a 432 pixel x 378 pixel image with over 2000 different 24-bit colors, all in a very precise pattern, a fractal shape as a matter of fact. In the time it is taking me to find any programming language that will let me do this, I suppose I could do it manually with a graphics editor, although this would be somewhat tedious.
I can create a 432x378 array of strings, where each string is the hexadecimal code for a 24-bit color. How can I turn this array into an image? Does anyone know of a programming language which DOES do graphics?
You can easily create .pnm file (gradient demo how to do this). Then install netpbm package and use for example 'pnmtopng' to convert .pnm file to a more popular format.
