CGImageCreateWithMask works great but the masked out area is black in my resulting image, how can I set it to be white?

Question

I\'ve masked out my image thusly:

    CGImageRef maskRef = [[UIImage imageNamed:@\"testMask2.png\"] CGImage];

CGImageRef mask = CGImageMaskCreate(CGImageGet         


        

Answer 1

Try this:

imageView.opaque = NO;
imageView.backgroundColor = [UIColor clearColor];

Also, the image used to mask should be black and white (not transparent).
