Hello everyone. I have a question that I'm sure is pretty easy,
although I haven't quite been able to smurf it.
Let's pretend that I have an NSBezierPath that describes some
region, and I would like to draw an NSImage ONLY in the path. I'm not
concerned right now with alpha, or any other component of the image.
Additionally, to make it easy, let's assume the path is blackColor.
Does anyone know how to do this?
See the method -croppedImage in CroppingImageView.m in:
http://developer.apple.com/samplecode/Sample_Code/Cocoa/
Cropped_Image.htm
In a nutshell, fill the path, and then composite the image over it
using the NSCompositeSourceIn operation.
