Hi,

one possibility, even so I doubt it is the most elegant, is to create a BitmapRepresentation of the view and get the color from this image. More elegant would be, if you would be able to use the information from the "tiling method", for example by storing the random colors in an array of kind.

Maybe some details on how you create the tiles would be helpful?

Cheers, Volker

Is there a way to get the color of a pixel or area of an NSView during the drawRect method? I'll be tiling the view with a grid of random colors but each tile is based on the colors around it. I'd prefer to call something along the lines of:

NSColor *aColor = [myView colorAtPoint: somePoint];

Rather than creating and filling a potentially quite large array of colors.
