Hi all,
I have a bitmap image (a jpeg) and need to translate, rotate, and scale
it. I'm not so much interested in displaying the result onscreen (except
for debugging). I've read up on NSImage and NSAffineTransform and it
seems to me that they are geared for display onscreen. What I'd really
like is to provide an NSBitmapImageRep and a transform matrix and get
back a new NSBitmapImageRep. Will I need to draw into some kind of
offscreen graphics context to do this? or use vImage?
Thanks for any tips,
--
