People who've found this useful should also check out PDFrasterFarian
. It does a similar conversion of PDF->image-LRF. It sadly lacks the beautiful interface, but, for now at least, gives much better results. It increases boldness and contrast of text, has better support for portrait/landscape, and gives true autocropping.
I hope that maybe you and I could work together to create a solution that has both a great GUI and great results.
