Description Jason Crain 2017-07-16 19:26:25 UTC

If you run pdftohtml on the PDF in bug #101770 (https://bugs.freedesktop.org/attachment.cgi?id=132659) It results in duplicated and jumbled characters.

Some PDFs draw text multiple times to emulate bold text or drop shadows.  The main TextOutputDev goes to a lot of trouble to remove this duplicated text.  pdftohtml should do this too.

pdf-example.html - from pdftohtml -s -noframes

I've attached the HTML file resulting from running "pdftohtml -s -noframes pdf-example.pdf".  I haven't attached the images but this should be enough to get the idea.  The HTML has several places where lines are duplicated.  Example:

<p style="..." class="ft10">1&#160;</p>
<p style="..." class="ft11">&#160;</p>
<p style="..." class="ft12">UPUTSTVO&#160;ZA&#160;PACIJENTA</p>
<p style="..." class="ft12">UPUTSTVO&#160;ZA&#160;PACIJENT</p>
<p style="..." class="ft12">UPUTSTVO&#160;ZA&#160;PACIJEN</p>
<p style="..." class="ft12">UPUTSTVO&#160;ZA&#160;PACIJE</p>
<p style="..." class="ft12">&#160;</p>
<p style="..." class="ft12">&#160;LUNATA</p>
<p style="..." class="ft12">LUNAT</p>
<p style="..." class="ft12">LUNA</p>
<p style="..." class="ft12">LUN</p>

I've elided the style attribute above to keep the lines a reasonable length.
