Hi there!
I think I found a bug in version 1.0.4:
If you crop a page you can aquire the coordinates for cropping by this handy selection tool the software includes, but if you try to use this a second time on an already once cropped page to crop it further, then the meassurements are off and the result is something completly different from what you selected.

I'm not sure what you are seeing.

Please start gscan2pdf with

gscan2pdf --log=log

and reproduce the bug, quit, and post the log file here.

Please include a test image three times: before you crop it, after the first crop, and then after the second crop - and describe why you think the program behaviour is wrong.

Hi ra28145! thanks for the response!
I produced a sample file="cropping_sample.png" and cropped it once to to cut away the red part file="DxyU6M9C2X.png" and tried to cut away the green part in a second cut which failed to produce the desired result, see "rzsKZwaHpc.png". The log file of this = "log.txt"
