RadPdfProcessing is a PDF document generation library, meaning it has no UI. With this in mind, it does support some utility classes and methods that allow to create the document in an easy manner, but they are not rendering engines.
As to the specific scenario, I suggest you take a look at the documentation of the RadFixedDocumentEditor
classes. The first one allows generation of documents in a flow-like manner, e.g. adding table-like structures, paragraphs, images and so on. The latter is very similar but additionally exposes API for drawing geometries
. So while the First Look and Bar Chart demos show images in their views, the funnel on the first one and the chart on the second are produced entirely with the API of the library and you could adopt a similar approach for your application.
Also, we've considered exposing API allowing to convert a XAML visual tree to PDF and this is logged on the public portal here
. You can vote for the functionality in order to increase its priority and follow it to be notified about any progress on the matter.
I hope this helps.
