Looks like rasterfarian is the best pdf to LRS converter out there. LRS is the format sony ebook uses; since it has the same screen as the kindle I'm thinking we can get this to work on it with some effort.

The project was abandoned due to copyright concerns - the developer packaged commercial sw with rasterfarian but this has since been corrected by a developer at http://kmfstudio.com/rasterfarian_252_patch.html

I'm hoping one of you egg-heads can help resurrect this sw and modify it for the kindle.

In order for it to be practical for kindle, I think we need someone with some know-how and interest to do the following:

1. Modify rasterfarian to actually CUT the pages in half rather than use LRF landscape mode. It already performs cuts in quarter page mode so I assume this is possible.

2. Modify rasterfarian to output a reformatted PDF or better, a kindle supported format (PRC/MOBI, AZW).

Today I think the easiest and likely best is MobiPocket for a PC. Just drop the PDF on it and you have a .mobi file that is readable on your device. It is not perfect but most fiction eBooks will convert fine while some fancy formatted text books may not look so good.

mobi publisher works fine for text only pdfs. but if you have ebooks with embedded graphics or made from scanned pages, you'll need something like rasterfarian.

PDFLRF does similar jobs as Rasterfarian and it can save the result as zipped PNG files.

If you find a way to convert a set of PNG files into one mobipocket file, using PDFLRF might solve your problem.
PDFLRF can cut the PDF pages to fit 6 inch sony reader screen either in landscape or portrait mode. I don't think you can cut the screen in half exactly, though. I would recommend you to try the program and how it performs.

pdflrf looks good, except how would we handle TOC creation?

TOC can be a problem since you will get a bunch of PNGs in a zip file without any information on document structure. If you need automatically created TOC, generating PNGs from PDFLRF cannot be of help, I am afraid. :o

ok.. thanks for suggestions, guys. it seems that raster has it all: TOC, auto-crop, color correction, batch processing and does them all reasonably well.

Hopefully all that's needed is someone with the know-how and time to modify it for the kindle.

Look forward to your responses.
