My LRFs don't contain any characters. When a PDF contains text, that text is turned into PNG images (it is rastered). This enables me to control the quality of font rendering, run post-processing "photoshop" filters, and preserve exact formatting. The images, though, turn out pretty small since they only have 4 colors and limited resolution. If you start with a PDF document that contains lots of pictures (especially high-res color), the end result will turn out much smaller because the information that the Sony Reader can't display gets stripped. However, if the PDF was just text and a few vectors (lines, circles, etc.) then the LRF will come out larger. Of course, given 2gb sd cards it doesn't really matter.
Daft Willie,
Maybe you're thinking of the overlap settings when you use the mode that splits a page four ways. Of course, you can also choose whether or not to do automatic cropping. Manual cropping, however, would be too impractical with a text interface. To do manual cropping I suggest first running the PDF either through Acrobat Pro (what I do) or JAP (which may give you even more control, but it preforms a rasterization step also and the final quality gets reduced a bit). If anyone knows any other PDF manual cropping programs, Please let us know (maybe I can just integrate it into the toolset). Manual cropping will be a big feature of pdfrasterfarian 3.0, whenever that sees the light of day.
