Hi Aspose support,
In out product we started to use EMF to PDF conversion via Aspose, and after some research with different ways and different Aspose libraries we found that the optimal one is to use Aspose.Words.dll to insert EMF picture into document, convert to Word document to PDF and then optimize PDF with Aspose.PDF.dll. In this case conversion speed and resulted PDF file size and quality are optimal.
Actually the base of the conversion method is taken from example: https://docs.aspose.com/display/wordsnet/Converting+a+Document#ConvertingaDocument-ConvertImageToPdfMethod
But with this method we noticed problems with content in resulted PDF file.
Aspose.Words.dll v 19.7.0
Watermarks are black and doubled in the saved/converted PDF.
WatermarksResult.png (208.6 KB)
WatermarksEMF.zip (3.8 KB)
Seer project codes for more details:
EmfToPdf.zip (6.0 KB)
Please help with this problem. Watermark should look as watermark, but not as black text through the document.
Thanks in advance.
