Day 38: PNGRepresentationWithInterlaced

NSImage’s TIFFRepresentation is nice, but they are quite big. PNG’s are always smaller and that’s why I have this little category on NSImage:

- (NSData *)PNGRepresentationWithInterlaced:(BOOL)interlaced
{
  NSBitmapImageRep *imageRep = [NSBitmapImageRep imageRepWithData:[self TIFFRepresentation]];
  return [imageRep PNGRepresentationWithInterlaced:interlaced];
}
