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.

Currently, when the PDFViewer is used with the latest pdf.js version 4.0.379 an error is thrown in the browser console. (Uncaught (in promise) Error: No "textContentSource" parameter specified.)

You can test the behavior in the Dojo linked here - https://dojo.telerik.com/@NeliKondova/eBUYEDAb. Run the example and wait for the pdf file to be loaded, then check the browser console. 

The latest Kendo version is compatible with pdf.js version 3.11.174. However, I would like the Kendo UI for jQuery to be compatible with pdf.js 4.x to avoid such misbehaviors.

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%.

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

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 PDFViewer requires the "unsafe-inline" keyword in the "style-src" directive.

### Reproduction of the problem

1. Enable CSP and set the "style-src" directive to "self":

<meta http-equiv="Content-Security-Policy" content="style-src 'self' https://kendo.cdn.telerik.com;"/>

2. Create a PDFViewer:

<div id="pdfviewer"></div>

<script src="https://cdnjs.cloudflare.com/ajax/libs/pdf.js/3.4.120/pdf.min.js"></script>
<script>
    window.pdfjsLib.GlobalWorkerOptions.workerSrc = 'https://cdnjs.cloudflare.com/ajax/libs/pdf.js/3.4.120/pdf.worker.min.js';
</script>
<script>
    $("#pdfviewer").kendoPDFViewer({
        pdfjsProcessing: {
            file: ""
        }
    });
</script>

A Dojo sample for reproduction: https://dojo.telerik.com/ugAyagIJ

### Current behavior

When the PDFViewer is initialized, the following Content Security Policy error is thrown:

Refused to apply inline style because it violates the following Content Security Policy directive: "style-src 'self' https://kendo.cdn.telerik.com".

### Expected/desired behavior

The the 'unsafe-inline' keyword must not be required in the "style-src" directive when using the PDFViewer widget.

### Workaround:

Add the following script before the PDFViewer initialization:

<script>
    var styles = {
        scroller: "k-canvas k-pdf-viewer-canvas k-pos-relative k-overflow-auto"
    };
    kendo.ui.PDFViewer.fn._renderPageContainer = function () {
        var that = this;

        if (!that.pageContainer) {
            that.pageContainerWrapper = $("<div />");
            that.pageContainerWrapper.addClass(styles.scroller);

            that.pageContainer = $(`<div class="k-pdf-viewer-pages" />`);
            that.pageContainer.css('--scale-factor', that.zoomScale);
            that.pageContainer.attr("tabindex", 0);

            that.pageContainerWrapper.append(that.pageContainer);
            that.wrapper.append(that.pageContainerWrapper);
        }
    };
</script>

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!

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 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?

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.

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.
