[jira] [Comment Edited] (PDFBOX-2069) PDF's with Tc before Tm are
getting incorrect spacing in PDFTextArea

That depends on the intention when extracting the content.
What kind result do we expect, some sort of visual formatting (WYSIWYG => P D F B o x) or a semantic interpretation (=> PDFBox)? Maybe that question is similar to adobes two different ways of extracting text. I some cases copy&paste produces different results than "save as text" ...

> 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]
