Hello!
There are problems with transparency (i.e. lots of bugs in MacOSX), but
here is what I understand to be the current state:
1. If you only draw to screen, you can just set alpha component in
NSColor and use it as any other color.
2. If you want to have PDF with transparent colors, you must use Core
Graphics routines, because AppKit strips alpha when not drawing to
screen.
3. And when using Core Graphics, CMYK text transparency seems to not
work (RGB works, though).
Regards,
izidor Jerebic

Hi,
I am looking to a way to draw with transparency. For example in my
NSView I want to fill transparent rectangles which can be superposed.
Is it simple as fill with colors with special parameters ? special
colors ?
Thanks for your attention,
Louis.
