I can't post images until I have 10 reputation points. I'll try to explain without them.
I have an image that is 35x29 pixels in size and overlayed on an image that is 168x46 pixels in size. The overlayed image is located at x/y pixel coordinates 73x12 from the top left corner of the 168x46 size image.
If the underlying image size was changed to 743x203, how do I calculate what the x/y pixel coordinates for the overlayed image should be changed to so that it appears in the same position? The overlayed image would also increase in size keeping its aspect ratio.
