Hi Telerik Support Team,
This is suggestion,can find only one viewer to view all type files,pls look http://groupdocs.com/apps/viewer/live-demo,this viewer first generate png and js file using pdf2json.exe and mudra.exe form pdf file.
So at first other than pdf file using Aspose dll convert into pdf file,and then generate png and js file form converted pdf.
Currently we did above way to view all types of file in viewer,so if in teleriik control ,it look more attractive way,like how ordinary button differe telerik button.
It just request/suggestion only,so not possible pls ignore it.
And compare 2 files interface possible in telerik control,in Notepad++ can do compare 2 files,it give different result .
