I think that what you need to investigate are vector drawings rather than bitmaps. It seems that you want to draw a picture and have it scale to any size area. You could try holding all of the co-ordinates in some array and then re-draw the image any time the area is resized, or you might try using a "metafile". I am not familiar with metafile use, but it seems that that is what you need.
