Hi all,
I'm newbie here in Cocoa. Sorry for duplicate posting of likely issues.
Say, I have a image file and I'd like to do some image process on it,
such as convolution.
For things like convolution vImage is the way to go if you can target
10.3 or later.

index.html
I can send some early code snippets for a side project that I am
working that outlines a way to use the vImage library from Cocoa,
nothing fancy but it works. I don't have it integrated with NSImage but
I could with a little more work (my project just does need that ability
at the moment).
