I would like to create an 8-bit grayscale image but I cannot find a color
space that uses only 1 8-bit value per pixel. Everything seems to either be
RGB, RGBA, or one color *plus* an alpha channel.
Am I going about this the wrong way?
Thank you in advance,
Simon
NSBitmapImageRep* outputImageRep = [[NSBitmapImageRep alloc]

bytesPerRow:(int)([inputImageRep
pixelsWide] * sizeof(unsigned char))
bitsPerPixel:(int)0];
