Getting information about paths and other graphical objects

[Robert Main <RM...@gmx.de>]

Hello. I have PDFs that e.g. have circles or filled rectangles in them which aren't images. How am I able to identify those and get information about them, such as position etc.? Someone told me those are paths, but I see no way to access them via PDFBox.

Greetings

Please take a look at the class
org.apache.pdfbox.pdfviewer.PageDrawer, methods #fillPath(int) and
#strokePath()

Here's an example:

class PrintPaths extends PageDrawer {

  @Override
  public void fillPath(int windingRules){
    System.out.println(getLinePath());
    super.fillPath(windingRules);
  }

  @Override
  public void strokePath(){
    System.out.println(getLinePath());
    super.strokePath();
  }
}
