Automatic black border removal and conversion to mono by ClearImage demo.

I convert color pictures of b&w pages to mono in order to reduce the size a picture takes on the disk. With thousands of document pictures stored on a disk, the size matters.

Finereader OCR can automatically convert color to mono on input (it is a legacy feature) but it prefers to deal with original color pictures.
