Thank you for the best PDF to LRF converter.
I've noticed two things, don't know if these are bugs:
- with -p and --nocrop options the pdf page is not filling the whole screen (looks like it has not been fit to cover whole screen). There is lots of free space at the right and at the bottom margins.
- by default color parameter has 16 shades, but PRS can display only 4. The output on the computer screen looks beautifully with 16 shades, but Sony PRS-500 is doing dithering to render this and I think it's causing some quality degrading. When I choose 4 shades I end up with some pages that are not white but gray. Looks like the color map doesn't have pure white and black, but algorithm is choosing the best 4 shades that match original page. I think that Sony Reader is not able to display at once 4 shades from e.g. 256 palette, but is only able to display exactly 4 shades, which means that dithering here also apply even if output image has only 4 colors in the map.
