You should have kept reading the docs. :-) Use -
compositeToPoint:operation:fraction: ... the operation and fraction
are how you specify how to draw the image. -compositeToPoint: doesn't
change anything - just composites the image as-is.

Hello,
I am trying to create a semi-transparent thumbnail for my
application when I perform drag and drop. The problem is, the
source image is not transparent. I know that you can draw the
NSImage transparent by using the compositeToPoint methods, but
those do not actually change the data. I need the actual NSImage
to contain the transparent image so that I can pass it to the
function:
dragImage:at:offset:event:pasteboard:source:slideBack:
How does an application like iPhoto create the transparent thumbnail?
Thanks in advance.
