While there's still some confusion how to properly generate PDF content for the iRex iLiad, MobileRead reader vvv came up with a promising-looking frontend utility called
BookDesigner that seems to utilize the open-source tool PDFCreator to transform content to PDF for the iLiad (and other e-book devices for that matter).
If you look at the
screenshot of BookDesigner in action, you'll notice that there are all kinds of useful parameters you can adjust to optimize the PDF output. According to vvv, it still needs some testing; but who knows, if you try to be nice to him, perhaps he'll hand out a copy to you.
