I suspect that using Quick Time or vImage/Core Image to perform efficient manipulation of bitmap pixel data may be more what the original poster wants.

Another interesting tool for working with images and treating one of the colors in the image as transparent is:

CGImageCreateWithMaskingColors

This allows you to take the image data and create a CGImage from it assuming that certain color ranges are mapped out (you could clamp the color range to just a single color if desired).

If you wanted to dump out the resulting transparent image you could simply use Image I/O (CGImageDestination).

Unfortunately, all this is Tiger only.

Scott
