Can anyone see what's wrong here ?
I always get "Context not created!".

[...]
   colorSpace = CGColorSpaceCreateLab(whitePoint, blackPoint, range);

   context = CGBitmapContextCreate (bitmapData,
                                   pixelsWide,
                                   pixelsHigh,
                                   8,
                                   bitmapBytesPerRow,
                                   colorSpace,
                                   kCGImageAlphaNone);

Check out <http://developer.apple.com/qa/qa2001/qa1037.html>. The number of color spaces, bpp, etc., that CGBitmapContextCreate supports is very limited. Lab is not one of the supported color spaces.
