Not sure if this is a possible cause for issues others have reported. I
found that when creating images from PDFs I was getting a lot of jumbled
text, bits overlapping others etc, and generaly it looked wrong. Turns out
after much digging and tinkering that the FontManager was returning the
wrong font even for standard fonts available in most environments.
The fix I put in was inside the iterations of the available AWT fonts inside
the loadFonts method of FontManager. The last line of the for loop I added:
envFonts.put(normalizeFontname(font.getPSName()),font);
This puts in the post script name which is quite often used inside PDFs from
what I have been seeing lately on my work. This now has a much better chance
of looking up the correct font. I now dont have overlapped words etc because
the font has a much better metric with what was expected.
I think this problem may be more prevelant on PDFs where the text has been
fully justified. I have run into a subsequent issues still plodding my way
through. Which is that I'm now left with large gaps in lines in the middle
of words because PDF box isnt rendering the word spacing correctly (might
also be character spacing) which is all down to the use of AWT rendering of
fonts which as far as I can tell wont allow for the kinds of control
required when rendering a whole string, the alternative seems to be to have
to render each character one by one with the appropriate displacement
between each glyph.
