Tilman Hausherr commented on PDFBOX-4399:
-----------------------------------------
[~jjcool] why are you removing the 3 lines in PDFMarkedContentExtractor ?
{code}
- addOperator(new BeginMarkedContentSequenceWithProperties());
- addOperator(new BeginMarkedContentSequence());
- addOperator(new EndMarkedContentSequence());
{code}
You are adding them in PDFGraphicsStreamEngine, but that one isn't extended by
PDFMarkedContentExtractor, so I'm wondering.
(I'm not saying it is wrong, I'd just like to understand, because now I wonder
whether {{PDFMarkedContentExtractor.beginMarkedContentSequence}} will ever be
called?)
