I guess another try at getting legibile low-vision fonts bites the dust... LRF and BD not supporting boldface or left justification or proper underlining really is dissappointing. The embedded fonts did work better than expected (at least on a 500-page document with all text in the same font), and I found the longer page turn time anageable. But there are some books that need boldface on a word-by-word basis.
And using large fonts with full justification and no hyphenation produces horrible results. I don't supposed BD and LRF support adaptive hyphenation?
Looks more and more like I'll have to surrender and create a flash image with more readable fonts and standardize on RTF. Or attempt to use bitmaps images instead.
