  • JPEG
  • PNG
  • SVG
var gauge = new ej.lineargauge.LinearGauge({
        allowImageExport: true
}, '#element');

PDF Export

To use the PDF export functionality, set the allowPdfExport property as 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 of the PDF document can be set as Portrait or Landscape.

var gauge = new ej.lineargauge.LinearGauge({
        allowPdfExport: true
}, '#element');

document.getElementById('export').onclick = () => {
        gauge.export("PDF", "Gauge", 0);
};

Exporting Linear Gauge as base64 string of the file

The Linear Gauge can be exported as base64 string for the JPEG, PNG and PDF formats. The rendered Linear Gauge can be exported as base64 string of the exported image or PDF document used in the export method. The arguments that are required for this method is export type, file name, orientation of the exported PDF document and allowDownload boolean value that is set as false to return base64 string. The value for the orientation of the exported PDF document is set as null for image export and Portrait or Landscape for the PDF document.

var gauge = new ej.lineargauge.LinearGauge({
        allowImageExport: true
}, '#element');

document.getElementById('export').onclick = () => {
        gauge.export('JPEG', 'Gauge', null, false).then((data) => {
            var base64 = data;
            document.writeln(base64);
        });
};
