Hello David,

During the past releases, we have worked on adapting the RadPdfViewer for WPF to work with the RadPdfProcessing library model. This functionality is currently in beta version and is not enabled by default as we are still working on polishing it before officially presenting it to all of our users.

However, we have exposed options to try the new model as we plan to migrate PdfViewer to use it. You can use the new model by setting the UsePdfProcessingModel property of the PdfViewer`s DefaultFormatProviderSettings to true:

this.pdfViewer.DefaultFormatProviderSettings.UsePdfProcessingModel = true; 

I slightly modified the AddDocumentContent SDK example (you can find it attached) from our GitHub repository in order to draw PathGeometry instead of drawing text.

You have the opportunity to test the new engine and let us know if you find something that you would like to see differently implemented or fixed. We encourage you to test the new behavior of the control and share your feedback to us so we can take any different points of view and scenarios you might have into account before the official change.

Regards,
