Bug report

Using the PDFViewer with the latest version of PDF.js (3.9.179) throws js exceptions. Version 3.4.120 is the last one, with which no js exception is thrown.

Reproduction of the problem

Dojo example: https://dojo.telerik.com/IHedIhur/3

  1. Open the devtools consolve and run the example.

Current behavior

The file is loaded, however, js exceptions are thrown:

The --scale-factor CSS-variable must be set, to the same value as viewport.scale, either on the container-element itself or higher up in the DOM. text_layer.js:480:14

Expected/desired behavior

No js exceptions when using PDF.js versions newer than v3.4.120.

Currently, the Print functionality works only with PDF.js. Provide a Print option when the PDFViewer is configured to use DPLProcessing.

Can you implement a scrollbar for the PDF viewer control? The current scrolling doesn't allow the user to grab the scrollbar and do the scrolling.

Currently, default zoom can be set through JavaScript in the Render event handler of the PDFViewer:

Attach the handler:

.Events(e => e.Render("onRender"))

The event handler:

<script>
    var firstRender = true;

    function onRender(e) {
        if (firstRender) {
            var combobox = e.sender.toolbar.element.find("[data-command=ZoomCommand][data-role=combobox]").data("kendoComboBox");
            combobox.value("fitToWidth");
            combobox.trigger("change");
            firstRender = false;
        }
    }
</script>

A better solution would be a dedicated configuration option that allows setting the default zoom when declaring the PDFViewer.

I load a pdf on a PDFViewer component using loadDefault function, but Open event is not fired.

Also, I want to scroll to the end of the document and for that, I need to retrieve the count of the pages and activate the last page in the render event, even it's called multiple times.

How can I get the count of the pages and scroll to the end of the .pdf document after it is loaded?

    @(Html.Kendo().PDFViewer().Name("documentViewer")
        .PdfjsProcessing(pdf => pdf.File(Url.Content("~/Content/data/default.pdf")))
        .Events(e => e
            .Error("(function(e) { onDocumentViewerError(e); })")
            .Render("(function(e) { onDocumentViewerRender(e); })")
            .Open("(function(e) { onDocumentViewerOpen(e); })")
        )
    )
...
<script type="text/javascript">
...

function loadDefault() {
    var docUrl = window.location.origin + window.location.pathname + "Content/data/default.pdf";

    var pdfViewer = $("#documentViewer").data("kendoPDFViewer");
    pdfViewer.fromFile(docUrl);
 }

onDocumentViewerRender = function(e) {
    console.log("render");

    if (goToEnd) {
         goToEnd = false;

         setTimeout(function () {
              var pdfViewer = $("#documentViewer").data("kendoPDFViewer");
              pdfViewer.activatePage(pagesCount); // how to get pagesCount
         }, 2000);
    }
}

onDocumentViewerOpen = function(e) {
    console.log("open"); // not shown in Console
}
...
</script>

Bug report

A server side exception:
System.OverflowException: 'Value was either too large or too small for a Double.'
is thrown on attempting to serialize an existing .pdf file converted to FixedDocument.

Reproduction of the problem

  1. Use the DPL Processing demo of the PDFViewer in the MVC demos project.
  2. Instead of the default sample.pdf load the Development Plan.pdf file provided in Ticket ID: 1467984
public ActionResult GetInitialPdf(int? pageNumber)
{
    //exception with Development plan.pdf file:
    string filePath = Path.Combine(Server.MapPath("~/Content/web/pdfViewer"), "Development Plan.pdf");
    //it works with the sample.pdf file:
    //string filePath = Path.Combine(Server.MapPath("~/App_Data"), "sample.pdf");
    FileStream stream = new FileStream(filePath, FileMode.Open, FileAccess.Read);
    JsonResult jsonResult;
    FixedDocument doc = FixedDocument.Load(stream);

    if (pageNumber == null)
    {
        jsonResult = Json(doc.ToJson(), JsonRequestBehavior.AllowGet);
    }
    else
    {
        jsonResult = Json(doc.GetPage((int)pageNumber), JsonRequestBehavior.AllowGet);
    }

    jsonResult.MaxJsonLength = int.MaxValue;
    return jsonResult;
}

Current behavior

The exception is thrown during the FixedDocument JSON serialization:

doc.ToJson()

at the following place: ConvertToList method in ArrayExtension class (Telerik.Web.PDF namespace)

Expected/desired behavior

No exceptions are thrown during serialization.

Currently, the search in PDF Viewer is performed on every keypress in the search input field. 

The search performance of the widget could be improved if there is a possibility to perform a search on pressing "Enter". Another valuable enhancement could be a configuration that allows the search to be performed after entering a certain number of symbols.

Please add keyboard scrolling support for the PDFViewer control. Scrolling through files with a lot of pages is very difficult.

Hi,

 

i tested the updated pdfviewer of version 2019.3.1023, but it did not work as expected.

I have some questions about usage und customizing

  1. How can i customize the toolbar actions, primary the print action/command? See the dojo link
  2. Is it possible to get the print window result of the pdf viewer?
  3. Is it possoble to call the print command? I tested the execute function, but it doesn't work. I get only an error (this is not an constructor...)
  4. the download function download every time a document.pdf, the assigned name is ignored

https://dojo.telerik.com/EmErekOB

 

Regards

Christian
