Tilman Hausherr commented on PDFBOX-2069:
-----------------------------------------
Yes... I also had another thought - lets say we output "PDFBox" with a big Tc
value, then it would look like this:
{code}
P D F B o x
{code}
How should this appear in text extration? As "PDFbox" or as "P D F B o
x"?
> PDF's with Tc before Tm are getting incorrect spacing in PDFTextArea

> I believe this because PDF streams with Tc before Tm are having the matrix
> applied to the Tc, which is contrary to my experience with graphic pipelines.
> Most PDF streams seem to to have Tc after Tm, and thus do not hit this
> situation.
> I have attached a patch to two files that corrects the problem for this file,
> and also works correctly on my test suite of about 40 files from other
> sources.
> The result for the attached file now becomes:
> Text in the area:java.awt.Rectangle[x=10,y=500,width=600,height=200]
