Hi,

Just to let you know that zoom parameter is not working at all in pdftohtml.

After comparing the Poppler version of pdftohtml to the original one on http://sourceforge.net/projects/pdftohtml/, i think that this patch is needed:

       delete psOut;

I've tested it successfully in my environment.
