Thanks David,
I am not sure that this will work for me in this instance as the
smaller image needs to be in a NSImageView so I can drag n'drop other
images in there.
Regards
Damien

I do this to composite one image over another:
CGContextRef ctx = UIGraphicsGetCurrentContext();
CGContextClearRect(ctx, rect);
CGContextDrawImage(ctx, rect, _meterImages[0]);
CGContextSetBlendMode (ctx, kCGBlendModeNormal);
CGContextDrawImage(ctx, rect, _meterImages[1]);
(iPhone example but the only difference I think is
UIGraphicsGetCurrentContext)

Hi All,
I have what is probably a stupid problem. In my window I have a
background NSImageView and I want to pop another much smaller one
on top. The one I am putting on top is a png with transparencies.
When I do this I get a rectangular image over my background but
what I want to see is only the non transparent parts of my image.
I have set the background colour of my image via [image
setBackgroundColor:[NSColor clearColor]] but I am perplexed with
the spectacular lack of any change.
I feel I am completely on the wrong path. Can someone point me in
the right direction?
Regards
Damien
If you can't be kind, at least have the decency to be vague.
