Print and Export in ASP.NET Core Linear Gauge
The rendered Linear Gauge can be printed directly from the browser by calling the print method. To use the print functionality, set the AllowPrint property as ”true“.
@using Syncfusion.EJ2;
<div id="container">
<button id="print">Print</button>
<ejs-lineargauge id="gauge" load="gaugeLoad" allowPrint="true" orientation="Horizontal">
<e-lineargauge-axes>
<e-lineargauge-axis minimum="0" maximum="120">
</e-lineargauge-axis>
</e-lineargauge-axes>
</ejs-lineargauge>
</div>
<script>
window.gaugeLoad = function (args) {
window.gauge = args.gauge;
}
window.onload = function () {
document.getElementById("print").onclick = () => {
window.gauge.print();
};
};
</script>
Export
Image Export
To use the image export functionality, set the AllowImageExport property as ”true”. The rendered Linear Gauge can be exported as an image using the export method. This method requires two parameters: export type and file name. The Linear Gauge can be exported as an image with the following formats.
- JPEG
- PNG
@using Syncfusion.EJ2;
<div id="container">
<button id="export">Export</button>
<ejs-lineargauge id="gauge" load="gaugeLoad" allowImageExport="true" orientation="Horizontal">
<e-lineargauge-axes>
<e-lineargauge-axis minimum="0" maximum="120">
</e-lineargauge-axis>
</e-lineargauge-axes>
</ejs-lineargauge>
</div>
<script>
window.gaugeLoad = function (args) {
window.gauge = args.gauge;
}
window.onload = function () {
document.getElementById("export").onclick = () => {
window.gauge.export('PNG', 'LinearGauge');
};
};
</script>
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“.
@using Syncfusion.EJ2;
<div id="container">
<button id="export">Export</button>
<ejs-lineargauge id="gauge" load="gaugeLoad" allowPdfExport="true" orientation="Horizontal">
<e-lineargauge-axes>
<e-lineargauge-axis minimum="0" maximum="120">
</e-lineargauge-axis>
</e-lineargauge-axes>
</ejs-lineargauge>
</div>
<script>
window.gaugeLoad = function (args) {
window.gauge = args.gauge;
}
window.onload = function () {
document.getElementById("export").onclick = () => {
window.gauge.export('PDF', 'LinearGauge', 0);
};
};
</script>
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.
@using Syncfusion.EJ2;
<div id="container">
<button id="export">Export</button>
<ejs-lineargauge id="gauge" Load="gaugeLoad" AllowImageExport="true" Orientation="Horizontal">
<e-lineargauge-axes>
<e-lineargauge-axis Minimum="0" Maximum="120">
</e-lineargauge-axis>
</e-lineargauge-axes>
</ejs-lineargauge>
</div>
<script>
window.gaugeLoad = function (args) {
window.gauge = args.gauge;
}
window.onload = function () {
document.getElementById("export").onclick = () => {
window.gauge.export('JPEG', 'LinearGauge', null, false).then((data) => {
let base64 = data;
document.writeln(base64);
});
};
};
</script>
Note: The exporting of the Linear Gauge as base64 string is not applicable for the SVG format.
