I just tried this application out and I think it been forgotten about. pdf2html rasterizes images to display on the web. Thing is its designed for a specific purpose. When used it makes a webpage with a black border and has a h1 title that says, "Lecture Notes". Probably not of much use to anyone. Reproducible: Always
app-text/poppler provides pdftohtml, among others. Upstream for this is gone as well.
it appears to work fine here, plus I've fixed bug #152263 it makes a webpage containing png's of each page of the pdf which is probably a good idea to keep around in case someone needs it and no issue is raised. pdftohtml tended to suck on my tests :/ thus: wontfix
