Only the line list got through.
Maybe the "invisible" lines are outside a clipping region? In that case
it would be much more difficult, one would have to adjust the list
according to it.

I had asked about this more than a year ago, and the answer was that
my basic method seemed correct. However I was never able to resolve
the issue, and now it has come up again. I am trying to detect, and
thereby ignore, invisible lines.
However, when trying to read either stroking (or nonstroking) colors
of the lines, I am getting that all the colors are always 0.0.
You had previously requested a PDF and some code in order to do
anything more.
Attached is:
1) a pdf that has a lot of invisible lines.
2) the core pieces of my Java code to process lines.
3) a listing of the lines found in this PDF.
4) a screenshot of examining a PDFGrahicsState object in the eclipse
debugger on a call to lineTo(), showing that all the colors I can get
are 0.0.
Thanks for your help
