Do you mean saving the frame in the bitmap itself or just displaying the image on screen within a frame?
In case you just want to display it on screen, one easy solution is to add a slightly larger panel behind the image.
Something like (pseudo-code):
AddPanel name_of_the_image.panel (same center (x,y) as the image center (x,y), only 3% larger)
If you need, I can provide you the exact B4A code later.
