Hi, Here I report an accessibility issue that I imagine should be quite easy to resolve. Related to read on a full white background is something that can be hard for some people. It would help to get a functionality to exchange white and black, read white text on black background. Or optionaly it could resolve too to change only the background from white #FFFFFF to grey #777777 (and keep the text in black). If the pdf contains images with white backgrounds it is not a problem to keep it unchanged, the problem occurs when the white area is huge.
