Angular Signature Pad

Angular component for szimek/signature_pad.

Install

npm install @almothafar/angular-signature-pad --save

Reference Implementation

* Live Demo
* Source

Usage example

API is identical to szimek/signature_pad.

Options are as per szimek/signature_pad with the following additions:
* canvasWidth: width of the canvas (px)
* canvasHeight: height of the canvas (px)
The above options are provided to avoid accessing the DOM directly from your component to adjust the canvas size.

``typescript

// import into app module

import { AngularSignaturePadModule } from '@almothafar/angular-signature-pad';

@NgModule({
declarations: [ ],
imports: [ AngularSignaturePadModule ],
providers: [ ],
bootstrap: [ AppComponent ]
})

// then import for use in a component

import { Component, ViewChild } from '@angular/core';
import { SignaturePadComponent } from '@almothafar/angular-signature-pad';

@Component({
template: ''
})

export class SignaturePadPage {

@ViewChild('signature')
public signaturePad: SignaturePadComponent;

private signaturePadOptions: NgSignaturePadOptions = { // passed through to szimek/signature_pad constructor
minWidth: 5,
canvasWidth: 500,
canvasHeight: 300
};

constructor() {
// no-op
}

ngAfterViewInit() {
// this.signaturePad is now available
this.signaturePad.set('minWidth', 5); // set szimek/signature_pad options at runtime
this.signaturePad.clear(); // invoke functions from szimek/signature_pad API
}

drawComplete(event: MouseEvent | Touch) {
// will be notified of szimek/signature_pad's onEnd event
console.log('Completed drawing', event);
console.log(this.signaturePad.toDataURL());
}

drawStart(event: MouseEvent | Touch) {
// will be notified of szimek/signature_pad's onBegin event
console.log('Start drawing', event);
}
}
