There is rectangular selection (orange lines) that should cover the cropped area. You should apply 'Page Box' manual mode and 'Content Box' auto. Apply it separately to even and...

What software do you used for creating pdf and djvu files?

Hi Brandon,

Many thanks for sharing effects of your work with all. I'm convinced that not only me but many other people keep fingers crossed for implementation of something similar to Adobe ClearScan.

Cheers.

Even lighting is very difficult to obtain in this kind of device. You may try to reduce it by: a. more square shape of the glass in orde...

I performed small comparison of the free method with Adobe Acrobat (Pro DC 15) output. It was much more tricky that I had expected. The comparison is based on the same book I previously scanned and processed. This is what I obtained: 1. Speed _____________ Adobe Acrobat ____ Open software Combining ...
