Increasing the font size when converting PDF
I've got a technical book that I want to convert to LRF. I tried PDFLRF, but once this was complete, the font was unreadably small on my PRS-505. I tried using the magnify buttons as I normally would, but the font stayed small.
Is there any known solution to this issue ? I'm not attached to the LRF format - I'm happy to shift this to anything that my reader can read.
