Hello!
In your dojo examples of your pdfViewer control you are loading pdf.js version 2.2.2 and with this setting you can select text inside the pdfViewer when the button "enable selection" is klicked.
https://dojo.telerik.com/eWUTEfeq
however, when i try to use the latest version of pdf.js (3.4.120) then the selection of text is not possible
https://dojo.telerik.com/IxuSuPuV
The last Version where it seems to work is pdf.js (3.1.81)
https://dojo.telerik.com/OxANudAx
Is this a known Issue? i don't like the idea of having to use such an old version of a js-library. Is this Problem related to kendo or to pdf.js?
Kind Regards,
Benjamin
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.
Bug report
The Actual Width option in the PDFViewer does not work as expected. The width rendered in the component does not match the actual width of the file.
Test scenario: a file that has 11.69 inches width ( approx. 1122 pixels ) is displayed with ~840px width.
Reproduction of the problem
- Open a pdf file in Chrome
- Press the 3-dot- icon next to the print Icon at the top right and press Document Properties
- Convert the Page Size dimensions from inches to pixels
- Open the file in the PDFViewer and compare the widths
Current behavior
The page width rendered from the Actual Width feature does not match the actual file width
Expected/desired behavior
The page width from the Actual Width option should match the actual page size of the file.

Go to:
Demo of core features in jQuery PDFViewer widget | Kendo UI for jQuery (telerik.com). Note that pdf has 3 pages.
In the pdf viewer component demo select the printer icon and a print preview window opens. When the print preview window opens, note that the window indicates that there are 5 pages to print in the print preview. One page is added before the pdf pages and one after. This happens regardless of the printer selected.
Expected behavior: only 3 pages of the pdf should show in the print preview window.

Bug report
Unable to print PDFViewer's PDF on Safari
Regression since 2022.2.802 , most probably related to the following fix in that release - #6923
Reproduction of the problem
- Run this Fullscreen Dojo in Safari - https://runner.telerik.io/fullscreen/uhIVIDoW
- Expand the overflow menu and tap on the Print tool
Current behavior
The Print Options window is loaded, but PDF pages are not shown in the Print preview. PDF pages content is not present in the saved PDF, if we save the printed content to file.
Expected/desired behavior
PDF pages are shown in the print preview window of Safari and can be saved to PDF
Working version 2022.2.621 - https://runner.telerik.io/fullscreen/abePoXEy
Environment
- Kendo UI version: 2023.1.117
- Browser: iPadOS 16.3 Safari
Bug report
When the PDFViewer is created and a file is loaded using the fromFile method a new thread will be created. That thread remains in memory and doesn't get destroyed when the entire widget is destroyed.
$("#pdfViewer").data("kendoPDFViewer").destroy(); $("#pdfViewer").empty();
Reproduction of the problem
- Open the Dojo
- Open the 'Memory' tab in the Developer tools
- Click the 'Create' and then click the 'Destroy' button
Current behavior
That created thread remains in memory and doesn't get destroyed.
Expected/desired behavior
The thread should get destroyed when the widget is destroyed.
###Workaround
A possible workaround:
kendoPDFViewer.processor.pdf.loadingTask.destroy();
The issue should be additionally researched as there are some leftovers in the JS Heap even when the workaround is used.

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.
Example: https://dojo.telerik.com/@iankodj/inuWOTUv
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
Please advise.

Dear Team,
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.

Bug report
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.
Reproduction of the problem
- Go to https://demos.telerik.com/kendo-ui/pdfviewer/index
- Set scale option to 100%
- Print to PDF using "Microsoft Print to PDF" printer. (The final result is the same compared to actual printing to a physical printer)
- For consistency set the following print options, e.g. in Chrome:
- Paper size: A4
- Pages per sheet: 1
- Margins: None
- Scale: Default
Current behavior
Text in printed PDF file is blurred
Expected/desired behavior
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.
