Another newbie request. - hypnotx - Jun 8, 2007 08:57 PM
Can anyone point me to some sample code that illustrates:
1.) Drawing a partial segment of a source image (png) to an NSImageView
2.) Drawing a partial segment of a source image (png) to a Custom View
Here is a little of what I am trying to get to work (using the NSImageView approach):
I am calling it with:
nextCardImage is an NSImageView Outlet.
Thanks for any help.

You are leaking memory badly. Before returning, release cardSheet and at the end do return [card autorelease]
Maybe it's better to use drawAtPoint or one of the composite methods. drawInRect is good, but you'll need to:
a) read what the docs say
b) experiment to get it right

Still playing around with it but now using a Custom View. Came up with this after looking at the Quartz tutorials on Dev Central but it is still a work in progress. I most certainly need to reread the sections on memory management. I'm guessing that I can define an NSRect for the portion of the source image and pass that as the fromRect variable to drawInRect instead of NSZeroRect. I think I am almost there.
