How can I apply geometric transformations during export while applying the Kendo UI Drawing API?


The following example demonstrates how to produce a PNG image of a page section at 4x the original resolution and applies an uniform 2x scale on the X and Y dimensions. The operation is carried out while the content is still represented in a vector form and no loss of quality occurs.

For more information, refer to the article on transformation API.

    <button type="button" class="export-img k-button k-button-md k-rounded-md k-button-solid k-button-solid-base">
      <span class="k-button-text">Export as Image</span>
    <div class="content">
      <div id="chart"></div>
