Hi,

I'm looking for some information on drawing graphic primitives on a Graphic LCD.
The primitives i'm interested in are, lines (Not horizontal or vertical ones offcourse) circles and elipses. Also angled arcs offcourse.
These should be the basic ones i'm looking for.

I want to program in C so please don't send me to much assembly examples.

Thanx, venz.
 

For lines drawing look on the net for "Bresenham algorithm".

Google gives many answers. The first of them as some C code :
