When the paint event goes into action(by itself or directly by calling invalidate/refresh) it loops through this collection of objects to be drawn, and draws them as such.

Another method I've considered but have yet to try is copying the image your drawing to, then draw onto that image. Once you're done drawing to the stored image, simply place it back - replacing the original image.
Thanks for your reply, as I'm new, could u please tell me what sort of codes should I use in order to apply the second method?
