Scan Image and SetRect Problem

[drdoctor]

So I'm only selecting the top left corner, and the bottom right corner? That makes sense but why were there 6 arguments in SetRect?

Can you give me an example like SetRect &a; topleftX; bottomrightX

I'm not sure if it's the X/Y values of the mouse or which/how many numbers your supposed to put in because I couldn't find SetRect in the manual.
