Joel Hirsh updated PDFBOX-3063:
-------------------------------
Attachment: whiteonwhitetext.pdf
I had two files with the same symptom, looks like different causes.
Attached is a different test, there is a nonvisible 3 to the left of the text
that comes through as white on white (stroking and nonstroking). I verified
that in both 1.8 and 2.0, and Tilman requested such a file.
The technique suggested by Tilman (adding all the operators) does work for 2.0,
so its not a major bug, but if nothing else that should be documented.
> Appears that getStrokingColor/getNonStrokingColor are broken

> I am using PDFTextStripper and overriding processTextPosition so that I can
> test for white on white text.
> In version 1.8 I called getGraphicsState().getStrokingColor() and
> getGraphicsState().getNonStrokingColor() to get the colors and then could
> test for white on white text.
> In version 2.0 I am making the same calls on the same file, but the PDColor
> returned for both methods never changes from PDColor{components=[0.0],
> patternName=null}
> In the attached file, there is some white text '661.37' just above and to the
> left of the 2.00. Can find it in Acrobat by searching or careful selecting
