There isn't much changed in LoadFromIntImage, but I need to lookup if the internal rawimage is shared correctly. In the worst case a pixelcopy is made, which is not necesary in this case. one little optimalisation is setting the size like: BmpMap.SetSize(Map.width * Tiles.Width, Map.height * Tiles.Height); Another optimalisation would be creating the RawImage directly and not through a bitmap. (but all those don't change a bit on loadfromrawimage) Marc _______________________________________________ Lazarus mailing list [email protected] http://www.lazarus.freepascal.org/mailman/listinfo/lazarus
