Export Custom Markup

The DevExpress.viz.exportFromMarkup(markup, options) method allows you to export SVG content, including SVG-based DevExtreme widgets, to an image or document.

The markup parameter accepts valid SVG markup (see the prepareMarkup() function in the code). If the exported document should contain an SVG-based DevExtreme widget, call the svg() method to get its markup.

The options parameter accepts an object whose fields configure export options. In this demo, we specify the width, height, format, and svgToCanvas fields. Refer to the method description for more information on these and other available fields.
