Summary: NSImage NSCompositeSourceOver operation doesn't
work
Project: GNUstep

Open/Closed: Open
_______________________________________________________
Details:
When doing the following, where you have image "a" and image "b":
[b lockFocus];
[a compositeToPoint: somePoint operation: NSCompositeSourceOver];
[b unlockFocus];
The expected result is that A will be laid in over B, this is not working
properly. This works on Mac OS X just fine, but doesn't function on
GNUstep.
I will attach an example program that illustrates this issue clearly in the
next couple of days.
