Hi, 

The feature is implemented and will be included in today's LIB release (v.2016.3.1010).
It will be included in our official R3 2016 SP1 release as well. 

Regards,

@chris.cavers Better later than never, we've added similar API to the one suggested by you, but in RadPdfProcessing. You can check the help article here: http://docs.telerik.com/devtools/wpf/controls/radpdfprocessing/model/imagesource. Note that currently RadRichTextBox  doesn't use RadPdfProcessing, so the limitation we be still valid in it; yet this is another good option to explore.

Use "pdftk uncompress" and also xpdf pdfinfo to dump the information about the PDF objects.  We've seen other PDF libraries reencode and visually degrade the images to a different compression format.  Ideally, one would be able to pass images through to PDF as they are added to the RichTextBox control.   This puts the image format and compression settings on the developer and then the PDF export is a pass-through without lossy recompression operation.   Gnuwin32 tiff2pdf.exe is a good example since it takes a single/multi-page tiff file and puts it into a pdf with adding only 3% extra bytes.
