i have a pdf file which appears to be text in layers and i am trying to highlight various figures in the spreadsheets with the yellow marker pen - unfortunately the document has a 'duplicate' watermark and whenever i try to highlight the text i need it always selects the watermark which seems to be on the top layer - is there a way to ignore this if not can i convert the contents of the page to an image which i can then highlight easily? TIA
This seems like an Acrobat or Reader question, not about the SDK. You should post in those forums.
There are couple of workarounds suggested for your case. See if this helps.
Workaround 1: Remove the watermark from the document using Edit tools>Watermark>Remove. Also, You can reorder text and watermark using "Objects" in Edit tools.
Workaround 2: Use Free form Tool with reduced Opacity for highlighting the current page as an image.
