Export Custom Markup
The DevExpress.viz.exportFromMarkup(markup, options) method allows you to export SVG content, including SVG-based DevExtreme components, to an image or document.
The markup parameter accepts valid SVG markup (see the prepareMarkup() function in the code). To get the markup of a component, call its svg() method. The options parameter accepts an object whose fields configure export properties. 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.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
