I'm trying to set margins when exporting to PDF using the Drawing API and can't get it to work. Here is a dojo. When you click the button to get the PDF, there is no margin around the chart. I'm assuming I'm doing something wrong, but not quite sure what.

Hi Jay,

Thank you for coming back to me.

I investigated further and you are right. Margin is applicable even if paperSize is "auto". The drawDOM syntax shall be a bit different:

          kendo.drawing.drawDOM($("#maindiv"))
            .then(function(root) {
            // Chaining the promise via then
            return kendo.drawing.exportPDF(root, {
              //paperSize: "A4",
              margin: 100,
              //landscape: true
            });
          })
            .done(function(data) {
            // Here 'data' is the Base64-encoded PDF file
            kendo.saveAs({
              dataURI: data,
              fileName: "calendar.pdf"
            });
          });

Please let me know if you have any questions.

Nikolay

Hi Jay,

To have the margins reflected in the PDF you have to set a paperSize:

           kendo.drawing.drawDOM("#maindiv", {
            paperSize: "A4",
            margin: { left: "2cm", top: "2cm", right: "2cm", bottom: "2cm" },
            landscape: true

Dojo demo: https://dojo.telerik.com/eCIgalUB

Hi Nikolay. The documentation for paperSize says when paperSize is "auto", it means the paper size will be just enough to fit the drawing. And then the documentation for margin says when paperSize is "auto", the dimensions are adjusted to include the margin. Taken together, it seems like margin is supported for paperSize "auto". 

Since you're saying it isn't, perhaps the documentation could make it more explicit that margin does not apply when paperSize is "auto".
