If you want the same blue highlight that NSButton applies to template images,
you can get the NSButtonCell to draw it into a graphics context and get an
image that way - I answered this when you asked about buttons specifically back
in June. (My bug requesting an NSImage method to do that is still open and
presumably unloved) Once you've got your buttonCell configured, do this:
NSRect bounds = NSZeroRect;
bounds.size = [template size];
NSBitmapImageRep *bmpImageRep =
[NSBitmapImageRep imageRepWithSize:bounds.size scale:scale]; // Utility
wrapper around imageRepWith32bitBuffer
[NSGraphicsContext saveGraphicsState];
NSGraphicsContext *bitmapContext =
[NSGraphicsContext graphicsContextWithBitmapImageRep:bmpImageRep];
[NSGraphicsContext setCurrentContext:bitmapContext];
[buttonCell drawImage:template withFrame:bounds inView:nil];
[NSGraphicsContext restoreGraphicsState];
return bmpImageRep;
