pdf2html converts one PDF into a series of ready-to-use HTML pages with 
PNG images of individual pages. It runs GhostScript at high resolution 
and processes the output into low-res, 8-bit grayscale PNG's, using 17x15 
times subsampling to achieve exactly 256 levels of gray. It is intended 
to convert PDF for online Web browsing where time is not critical but 
quality is desired.
