These features allow a user to export your widget into a document or print it. When exporting is enabled, the "Exporting/Printing" button appears in the widget. A click on it invokes a drop-down menu that lists exporting and printing commands. The following formats are supported for exporting into: PNG, PDF, JPEG, SVG and GIF.
This option supports the following colors:
- Hexadecimal colors
- RGB colors
- RGBA colors
- Predefined/cross-browser color names
- Predefined SVG colors
Enables the printing feature in the widget. Applies only if the export.enabled option is true.
Specifies the URL of the server-side proxy that streams the resulting file to the end user to enable exporting in the Safari browser.
Generally, exporting is performed using client-side API in browsers. However, the Safari (integrated in Mac OS) browser does not implement an API for saving files. In this instance, the widget can POST the content to a server-side proxy, which will stream the file back to the end user. To enable this functionality, set the export.proxyUrl option to the proxy, which will stream the file to the end user. When implementing the proxy, take the following information into account.
- Your proxy will receive a POST request with the following parameters in the request body: fileName, contentType (the MIME type of the file) and base64 (the base-64 encoded file content).
- The proxy should return the decoded file with the "Content-Disposition" header set to attachment; filename="
