-----------------------------------------
Same problem for PDFBOX-1628, PDFBOX-1794, PDFBOX-1145, I'm changing the title.
> Text extraction gets nothing / zero font height
> -----------------------------------------------

> Key: PDFBOX-2023
> URL: https://issues.apache.org/jira/browse/PDFBOX-2023
> Project: PDFBox
> Issue Type: Bug

> Affects Versions: 2.0.0
> Reporter: Tilman Hausherr

> Fred Andrews posted this to the user list and I can confirm that text
> extraction gets nothing:
> I am using PDFTextStripper on some PDF statements from Bank of America, and
> everything is coming through as zero height. I traced it down to
> getFontHeight in org.apache.pdfbox.pdmodel.font.PDSimpleFont, which is indeed
> getting zero. The font is a type 3 font and I'm not sure how it should work,
> but getFontHeight is calling getAFM() and that is returning a null because
> its not a type 1 font. Then in the next section in getFontHeight there are
> no font descriptors, and the zero just flows through all the way through
> getFontHeight.
> I searched for anything I could key on to calculate the font height but
> couldn't find it. The font size is claimed to be 20 by getFontSize(),
> although it appears to be more like 8. I did trace to where it got a font
> size command of twenty, but somehow I'm assuming that would need to be
> scaled, and I can't see where that might come from.
> The font width on the other hand looks accurate, and I would think something
> similar to that would be needed, but would really appreciate some guidance on
> how it should work. If I have clue on how it should work I can see what I
> can do to implement it.
> This file displays fine in Acrobat and edits fine in Nitro, so it can't be
> that invalid.
