create a line

[Kiti]

I want to make a cheat for Yahoo Pool. It has a short line which shows you where the ball will go. The first thing I wanna do is make that line longer. How I want to do this: Pixelsearch after the line's color, get the coords of the first and last pixel in the line, find the relative position between them, and then draw a second line from the last point of the already existing one, so it will double in length. But I don't know how to draw that line... I was thinking of making dozens of 1 pixel in width/height GUI... Is there any better way?

Look at my Radar project in my signature.

There is function MalujKriz() - DrawCross() which do almost exactly what you want.

It paints red cross (see screenshot) over picture on my GUI.
