What are you trying to accomplish?

Actually I'm recycling an old project of mine, a GIMP-Plugin for removing perspective distortions form input pictures, to Cocoa. From a given set of reference points I calculate a calibration matrix of sorts. This is used to obtain - for each pixel in the output-pic - the color of the corresponding, non-distorted point from the source- image. I receive the correct values from my math-routines, but am quite unable to write them to a visible output. I'm attempting to write them to a (focussed) NSBitmapImageRep *outRep, which in turn is passed to an NSImage outputImage in order to be drawn into an NSImageView. But the ImageView remains empty, and I don't know why.

Any hints?
