We can get the image file as base64 string for the JPEG and PNG formats. The linear gauge can be exported to image as a base64 string using the export method. There are four parameters required: image type, file name, orientation of the exported PDF document which must be set as null for image export and finally allowDownload which should be set as false to return base64 string.

PDF Export

To use the PDF export functionality, we should set the allowPdfExport property to true. The rendered linear gauge can be exported as PDF using the export method. The export method requires three parameters: file type, file name and orientation of the PDF document. The orientation setting is optional and “0” indicates portrait and “1” indicates landscape.
