Here's a simple method for resizing. I made it a category of NSImage.
- (NSImage *)resizedImageForSize:(NSSize)size
{
NSImage *resizedImage = [[[NSImage alloc] initWithSize:size] autorelease];
[resizedImage lockFocus];
[self drawInRect:[resizedImage bounds] fromRect:[self bounds]
operation:NSCompositeSourceOver fraction:1.0];
[resizedImage unlockFocus];
return resizedImage;
}
