I was thinking that it would be nice if iRex allowed us to add some cropping information to the manifest file.
It would be great if, on a per document basis, we could add something like (hope this comes through OK) ...
The PDF renderer could generate a larger page that is then cropped by the specified number of pixels before displaying.
This would allow the user to reduce the amount of white space around the pages by as much as they prefer.
I'm suggesting this for the case where one only has the PDF (I have a lot of reference books I've purchased in PDF format that I don't have the source for).
