Angular2 Component wrapper for szimek / signature_pad
npm install angular2-signaturepad<< THIS IS NO LONGER IN USE BY OWNER. PROBLEMS CAN AND DO EXIST. PRs ARE SUPER WELCOME, BUT I CAN NOT IDENTIFY WHAT YOUR ISSUES ARE, NOR WILL I CHANGE THINGS BECAUSE ANGULAR HAS CHANGED IN THE YEARS SINCE I WROTE THIS >>
npm install angular2-signaturepad --saveAPI 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 'angular2-signaturepad';
...
@NgModule({
declarations: [ ],
imports: [ SignaturePadModule ],
providers: [ ],
bootstrap: [ AppComponent ]
})
// then import for use in a component
import { Component, ViewChild } from 'angular2/core';
import { SignaturePad } from 'angular2-signaturepad/signature-pad';
@Component({
template: '
})
export class SignaturePadPage{
@ViewChild(SignaturePad) signaturePad: SignaturePad;
private 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');
}
}
