Deskew is a command line tool for deskewing scanned text documents. It uses Hough transform to detect "text lines" in the image. As an output, you get an image rotated so that the lines are horizontal.

Parsing of given background color is not working correctly for some inputs and it's impossible to use e.g. 100% transparent black:

-b 00000000 => 0xff000000
-b 000000a2 => 0xffa2a2a2
