ngx-signature-pad

Angular component for szimek/signature_pad.

Install

npm install @viablelogic/ngx-signature-pad

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 { SignaturePadModule } from '@viablelogic/ngx-signature-pad';

...

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

// then import for use in a component

import { Component, ViewChild } from '@angular/core';
import { SignaturePad } from '@viablelogic/ngx-signature-pad/signature-pad';

@Component({
template: ''
})

export class SignaturePadPage{

@ViewChild(SignaturePad) signaturePad: SignaturePad;

signaturePadOptions: Object = { // 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() {
// will be notified of szimek/signature_pad's onEnd event
console.log(this.signaturePad.toDataURL());
}

drawStart() {
// will be notified of szimek/signature_pad's onBegin event
console.log('begin drawing');
}
}
