PDFBox 2.0: how to detect bold text here

Question

I know there many ways to do bold text in PDF, most common are "bold" keywords in TextPosition.getFont(). However, in attached document I was not able to find why that bold text is actually bold:

Visually it looks like each character is duplicated twice, however, I don't see that in TextStripper.writeString Is there anything else can make text bold? thanks in advance!

Answer 1

Your file uses text rendering mode 2 (fill and stroke, aka RenderingMode.FILL_STROKE ). This simulates bold. You can get the current mode by calling getGraphicsState().getTextState().getRenderingMode() in a class that extends the stripper.
