We apply watermaks to PDF in our application.
We get pdf document from disc, apply watermarks and save document as new pdf.
Sometimes it works correct.
But sometimes new pdf is broken.
I try to open broken pdf by Adobe Reader (any version) and get message:
"Cannot find or create font 'Tahoma'. Some charters may not display or print correctly."
Text in watermarks shows as circle.
I attached 3 PDF (original + 2 with watermarks).
It is reproduced with Aspose.pdf 7.0, 7.2, 7.3.
How can we fix this issue?
