I recently downloaded a free book on carpentry which has an unusual feature on the diagrams - although the background colour of the page is pure white the section which has the drawing on is cream - this is reasonably clear using the built in viewer in calibre but when transferred to my Sony PRS300 is too faint to view. Is there anything that can be done in calibre or is this outside the scope of this programme?

Would appreciate any help as the book appears quite interesting.

Cheers,
