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.

I have created the PDF viewer and it works ok with most of PDFs except for those that have electronic signature. The signature section is blanked out. Would you have any fix or workaround for the problem?

Hello,

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?

Thanks,

Greg

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.

I'd like to ask if you plan to add a feature to PDFViewer allowing opening files secured with an owner password.

Both Chrome and Firefox now have native PDF viewer support including the ability to display and navigate bookmarks within the document.  Kendo’s control doesn’t have this functionality, but it’s possible to implement since PDF.js does and the Kendo control supports PDF.js rendering.

We’d really like to have a common UI for viewing documents within our web application, but we’re currently forced to render PDFs natively for Chrome and Firefox and with limited bookmark functionality for Internet Explorer by way of partial bookmark functionality we’ve implemented on top of the Kendo control.

Allow bookmarks to be set in the PDFViewer’s configuration during initialization, and then add a method to allow them to be scrolled-to by id.  The bookmarks would simply be y-coordinate/page number pairs. It’d also be nice if the viewer could read the bookmarks directly, but not entirely necessary with PDF.js rendering since they can be read from PDF.js

Ideally, you could also expose the raw PDF.js document object used by the PDFViewer so that it could be used instead.

Expose the ability to show interactive inputs similarly to the PDF.js library.

Bug report

PDF with a mixture of portrait and landscape pages shows incorrect page numbers in PDFViewer

Reproduction of the problem

Load a PDF with mixture of portrait and landscape pages.

Environment

jQuery: 3.4.1

Kendo UI version: 2024.3.1015

How can I add a button for full screen/exit full screen for the pdf viewer. I would like to keep the navigation

Hi,

 

Is a thumbnail/page viewer in discussion? It would be a real advantage to be able to see thumbs of pages alongside the page viewer.

An example using a different sdk is shown below.

It would be awesome if the PDFViewer control could be configured to display two pages side-by-side like a flipbook.

I'd like to request for the inclusion of PDF comments for the Kendo UI PDFViewer.

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

1. Run this Fullscreen Dojo in Safari - https://runner.telerik.io/fullscreen/uhIVIDoW
2. 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

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

1. Open a pdf file in Chrome
2. Press the 3-dot- icon next to the print Icon at the top right and press Document Properties
3. Convert the Page Size dimensions from inches to pixels
4. 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.

Environment

• Kendo UI version: 2023.2.606
• Browser: [all ]

Currently, if you zoom a page beyond 200% on an iOS device the page goes blank. The issue also occurs on Android devices if you try to zoom beyond 300%.

Hi Team,

I understand at the moment there is a limitation to exporting Hierarchical Grids to PDF.  I would like to request in the future a way to somehow overcome this.  

Thank you!

Hi Team,

I would like to request a way to hide/disable the new scroller for the Kendo UI PDFViewer.  

Thank you!

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

1. Open the Dojo
2. Open the 'Memory' tab in the Developer tools
3. 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.

Environment

• Kendo UI version: 2022.3.913
• Browser: [all ]

The PDF.js library supports sending xhr with credentials. Please expose this option so credentials can be specified.

Hello,

I would like to request the Kendo UI PDFViewer to allow the functionality of containing multiple pdfs.  Additionally, include a way for the user to cycle through them like having next and previous buttons.

Thank you!
