I think that nobody asked about possible implementation of white-threshold before.

It would be nice to have possibility to just choose between 0 and 255 for pdf scans with darker background.

Kindle DX White has poorer contrast, 7:1 to Graphite's 10:1, so I usually transform such pdfs directly with A-Pdf-to-Black-White application or k2pdfopt or sometimes indirectly by exporting pdf to images and then back to pdf after tone adjustment.

Will this pose a problem ?
