PDF Export
The Diagram provides a built-in PDF export functionality.
For a runnable example, refer to the demo on exporting the Diagram to PDF.
Getting Started
To enable PDF export in the Diagram:
- Introduce a button and handle its
clickevent. Export the Diagram within the handler.
<button class='export-pdf k-button'>Save as PDF</button>
<script>
$(".export-pdf").click(function () {
$("#diagram").getKendoDiagram().saveAsPDF();
});
</script>
- Include the Pako Deflate library in the page to enable compression.
To enable PDF export in the Diagram through code, call the saveAsPdf method.
<button class='export-pdf k-button'>Save as PDF</button>
