Fine. Although this is not the correct way to solve it.

Does your scanner use a black or a white background or anything else?
The 25 is a bug, I will replace it by 55.
The routine does search pixels that differ from the background. The backround
has to be black or white. When one pixel is found that differs with a brightness
of about 20% of the visible range the frame position is found.
The test is done with the gamma corrected preview, so you will get different results
with different gamma/brightness/contrast settings.
