Hello!

I am trying to display a PDF file in the RadPdfViewer that is shown as having a white background in other PDF Viewer programs (SumatraPDF, Adobe Acrobat Reader, ...), but in the RadPdfViewer it shows a red background. Is this a bug or is my file broken somehow? Or am I missing a setting that changes this behavior?

Cheers

Hello Nico,

Thank you very much for the screenshots and the file. We will need a bit more time to investigate this and I'll write to you as soon as possible, hopefully within the next couple of days. I apologize for the inconvenience.

Hello,

Once again, please, accept my apologies for the delay. The reason behind the red color is that, roughly said, this color is present in the PDF file, but there is a functionality which overrides it and which is currently not implemented in RadPdfViewer. It is already present in our backlog and you can find the link to the public item here: PdfViewer: Add support for Transparency Group XObjects If you'd like to, you can upvote and subscribe to the item, which will both increase its priority and notify you about any development.

As for a workaround, the only one that is applicable would be to edit the original file, more specifically the red background that is present in it. Whether this is feasible for your case depends on the specifics of your scenario, of course.

Please, let me know if you have any further questions or comments.

Regards,
Anna
