[poppler] Lines in images get from pdftoppm overlapped

[William Bader]

I think that this is related to https://bugs.freedesktop.org/show_bug.cgi?id=78042 where text had an invalid size or non-invertible font matrix.
Also, pdftops produces the diagnostic "Syntax Warning: Invalid Font Weight", so the invalid font attribute is probably "FontWeight".
I think that some applications add invisible supplemental text that way because Acrobat does not show it.

Subject: [poppler] Lines in images get from pdftoppm overlapped

Hi All,
I tried pdftoppm -png wrongline.pdf and get png images for this pdf. However, on the image of the first page, I can see lines overlapped. Is this a bug or some bad data in that pdf?
Thanks
