Drawing lines,angles&Circles on Graphic LCD.

[venz]

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 :

Hi

I've now a best idea : a page on "programmers heaven's" site
give you access to many 2D drawing algorithms anc codes.

--> h**p://www.programmersheaven.com/zone10/cat458/

You will find and download all what you are looking for !
