I have experience with OpenText Brava Enterprise. I've had the chance to integrate their Viewer in our in-house document management system. This viewer opens up to 100 file formats and allows to add/remove/edit annotations on files and saves these annotations as a separate layer on top of the file. So next time you open the same file to view, you can load the annotations (via API) calls and place the layer of annotations on top.
I was hoping I would see the same thing with Telerik PDF Viewer (and I am aware this works only for PDF). To allow the user to add a Text comment, Shapes, Stamps, Image, PDF Bookmark, etc.
In PDFViewer, underlines increase size when zooming in/out.
The underlines increase their size.
The underlines should remain the same.
When opening the Zoom ComboBox in the PDFViewer, the value is changed to NaN.
The value is changed to NaN.
The value should match one of the ComboBox items.
Tools' tooptips are localized and can be modified via messages. However, the tools in the overflow menu (when window size is resized) have the original tool text.
The print functionality does not work when using chrome on android and safari on iphone.
I tested at the url https://demos.telerik.com/kendo-ui/pdfviewer/index
When trying to print a file from the PDF Viewer, if the user wants to use the system print dialog, the printing dialog gets closed, but the system dialog does not appear.

Currently, the feature for open a pdf with password protection it's not supported, any solution for this, is necessary because many pdfs use security for confidentiality.

A valid PDF file cannot be opened after a corrupted file was loaded
It should be possible that a valid PDF file can be opened after a corrupted file has failed to be opened.
As like in other frameworks (https://pspdfkit.com/) we should have the in built option to rotate the PDF pages using Kendo UI PDFViewer widget.
Currently the result of PDFViewer printing is affected by PDFViewer scale option. When scale is less than 200%, the letters in the printed PDF appear blurred.
Text in printed PDF file is blurred
Text in printed PDF file is clear.
NOTE: Clear text may be achieved if PDFViewer scale option is set to 400% on the demo before printing.
Additional blank page is added in Chrome when printing a file with specific size.
A reproduction file for the problem can be found in Ticket ID:

I try to show the pdf viewer in an kendo window, is there any problem known?
Could you help me how we can turn on Selection on PDFViewer in jQuery Solution ?
In the above solution I can not select any of the below options.
The PDF.js library supports sending xhr with credentials. Please expose this option so credentials can be specified.
I have an 8mb PDF files that I need to be able to search, however when I click on the search tool the entire page starts responding.
This issue happens in your hosted demo. It seems to come as a result of images in the PDF.
What do I need to do to have it work properly?
