Get a pixel color on the desktop
-
Is there a function that will retrieve the pixel color on a daesktop location? Or a function that will alliow me to save the desktop as a bitmap?
-------------------------------------------------------- 1 line of code equals many bugs. So don't write any!! My mad coder blog

There was an article of a simple screen effect not too long ago. I lost the link to it, but here's the basic code:
int screenWidth = Screen.GetBounds(new Point(0, 0)).Width;
int screenHeight = Screen.GetBounds(new Point(0, 0)).Height;
Bitmap screenShot = new Bitmap(screenWidth, screenHeight);
Graphics gfx = Graphics.FromImage((Image)screenShot);
gfx.CopyFromScreen(0, 0, 0, 0, new Size(screenWidth, screenHeight));After that, you should be able to use
GetPixelon thescreenShotvariable to get pixel values from the desktop.

Just noticed that .Net 2.0 now supports CopyFromScreen() feature, which should be quite handy for GDI+ developers. Thanks for posting, Dustin.
