Well, it is not really a
cropping problem in itself. As one can see
here, the png's look just fine. However, when I open the imp file (either on EB-1150 or on the computer) the scroll bar of the EB-1150 at the bottom of the screen overlaps a little bit with the image and the first letters of the words in the text cannot be seen.
Also, in some pages, the last line of text in the page is being "cut" by the crop, and becomes completely illegible, as one can see
here . One possible solution that I can see is to crop the pages so that the bottom of one page would overlap with the top of the next page. In case the text is being cropped and the last line is illegible, this solution would allow one to read the line in question on the next page. Of course, this would probably generate some redundancies, but it's preferable to have the same line of text twice than not to have it at all.
