DPL Processing
You can configure the PDFViewer to use the Telerik Document Processing library for PDF processing.
DPL Processing is in its beta version and has the following limitations:
- The clipping of elements and gradients is currently not supported.
- SVG or encoded images in other formats might not render correctly.
Requirements
- DPL Processing depends on the
Telerik.Web.PDFassembly. - To use DPL Processing in a project, it must target 4.6.2 .NET Framework.
- The
Read.Urloption is mandatory, theOpenandDownloadoptions are mandatory if the respective tools are displayed in the toolbar.
Basic Configuration
The following example demonstrates how to configure the PDFViewer to use DPL Processing.
@(Html.Kendo().PDFViewer()
.Name("pdfviewer")
.DplProcessing(dpl => {
dpl.Read(r => r.Url(Url.Action("GetInitialPdf", "PdfViewer")));
dpl.Upload(upload => upload.Url(Url.Action("GetPdf", "PdfViewer")).SaveField("file"));
dpl.LoadOnDemand(true);
})
.Toolbar(toolbar =>
toolbar.Items(items =>
{
items.Add().Command("PageChangeCommand").Type("pager").Name("pager");
items.Add().Name("spacer").Type("spacer");
items.Add().Command("OpenCommand").Type("button").Name("open").Icon("folder-open");
})
)
.Height(1200)
)
