To use the print functionality, we should inject the PrintService
into the @NgModule.providers
and set the allowPrint
property to true. The rendered linear gauge can be printed directly from the browser by calling the method print
.
import { Component, ViewChild } from '@angular/core';
import { PrintService, LinearGaugeComponent } from '@syncfusion/ej2-angular-lineargauge';
@Component({
selector: 'app-container',
template: `
<ejs-lineargauge id="gauge-container" [allowPrint]=true #gauge>
</ejs-lineargauge><div> <button id='print' (click)='print()'>Print</button></div>`,
providers: [PrintService]
})
export class AppComponent {
@ViewChild('gauge')
public gaugeObj: LinearGaugeComponent;
ngOnInit(): void {
public print(){
this.gaugeObj.print();
};
}
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { LinearGaugeModule } from '@syncfusion/ej2-angular-lineargauge';
import { GaugeTooltipService } from '@syncfusion/ej2-angular-lineargauge';
/**
* Module
*/
@NgModule({
imports: [
BrowserModule, LinearGaugeModule
],
declarations: [AppComponent],
bootstrap: [AppComponent],
providers: [ GaugeTooltipService ]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
To use the image export functionality, we should inject the ImageExportService
into the @NgModule.providers
and set the allowImageExport
property to true. The rendered linear gauge can be exported as an image using the export
method. The method requires two parameters: image type and file name. The gauge can be exported as an image in the following formats.
import { Component, ViewChild } from '@angular/core';
import { ImageExportService, LinearGaugeComponent } from '@syncfusion/ej2-angular-lineargauge';
@Component({
selector: 'app-container',
template: `
<ejs-lineargauge id="gauge-container" [allowImageExport]=true #gauge>
</ejs-lineargauge><div><button id='export' (click)='export()'>Export</button></div>`,
providers: [ImageExportService]
})
export class AppComponent {
@ViewChild('gauge')
public gaugeObj: LinearGaugeComponent;
ngOnInit(): void {
public export(){
this.gaugeObj.export('PNG', 'Gauge');
};
}
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { LinearGaugeModule } from '@syncfusion/ej2-angular-lineargauge';
import { GaugeTooltipService } from '@syncfusion/ej2-angular-lineargauge';
/**
* Module
*/
@NgModule({
imports: [
BrowserModule, LinearGaugeModule
],
declarations: [AppComponent],
bootstrap: [AppComponent],
providers: [ GaugeTooltipService ]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
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.
import { Component, ViewChild } from '@angular/core';
import { ImageExportService, LinearGaugeComponent } from '@syncfusion/ej2-angular-lineargauge';
@Component({
selector: 'app-container',
template: `
<ejs-lineargauge id="gauge-container" [allowImageExport]=true #gauge>
</ejs-lineargauge><div> <button id='export' (click)='export()'>Export</button></div>`,
providers: [ImageExportService]
})
export class AppComponent {
@ViewChild('gauge')
public gaugeObj: LinearGaugeComponent;
ngOnInit(): void {
public export(){
const promise = this.gaugeObj.export('PNG', 'Gauge', null, false);
promise.then((data)=>{
document.writeln(data);
})
}
}
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { LinearGaugeModule } from '@syncfusion/ej2-angular-lineargauge';
import { GaugeTooltipService } from '@syncfusion/ej2-angular-lineargauge';
/**

*/
@NgModule({
imports: [
BrowserModule, LinearGaugeModule
],
declarations: [AppComponent],
bootstrap: [AppComponent],
providers: [ GaugeTooltipService ]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
To use the PDF export functionality, we should inject the PdfExportService
into the @NgModule.providers
and 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.
import { Component, ViewChild } from '@angular/core';
import { PdfExportService, LinearGaugeComponent } from '@syncfusion/ej2-angular-lineargauge';
@Component({
selector: 'app-container',
template: `
<ejs-lineargauge id="gauge-container" [allowPdfExport]=true #gauge>
</ejs-lineargauge><div> <button id='export' (click)='export()'>Export</button></div>`,
providers: [PdfExportService]
})
export class AppComponent {
@ViewChild('gauge')
public gaugeObj: LinearGaugeComponent;
ngOnInit(): void {
public export(){
this.gaugeObj.export('PDF', 'Gauge', 0);
};
}
}
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { LinearGaugeModule } from '@syncfusion/ej2-angular-lineargauge';
import { GaugeTooltipService } from '@syncfusion/ej2-angular-lineargauge';
/**
* Module
*/
@NgModule({
imports: [
BrowserModule, LinearGaugeModule
],
declarations: [AppComponent],
bootstrap: [AppComponent],
providers: [ GaugeTooltipService ]
})
export class AppModule { }
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AppModule } from './app.module';
enableProdMode();
platformBrowserDynamic().bootstrapModule(AppModule);
Note: The exporting of the linear gauge as base64 string is not supported in the PDF export.
