Pocketbook 912 - letters contrast in PDF books?
Since this device has multiple levels of grey, I notice that in some PDF books, if zoom is on lower level, letters as so light so they are barely visible.
I wouls like to know is there a way to increase contrast or to put device in black/white mode (without levels of grey) in such cases?
Black/White mode would increase visibility of small letters on screen, I think.
Also, it would be interesting to have a way to "crop" white book margins in PDF books. Zooming can do the trick, but I think white space crop could be done on OS software level.
Maybe this can be interesting for new firmware version (if it ever comes).
