lathonez / angular2-signaturepad-demo Goto Github PK

It's a great job for all ng2 lover. Thanks!
Could it be possible to give couple of lines demo codes about save signature and reload signature?
It shows black for me when I do this:
`
public save() {
this.tmpURL = this.signature;
}
public load() {
this.signaturePad.clear();
// Unbinds all event handlers
this.signaturePad.off();

// Rebinds all event handlers
this.signaturePad.on();

console.log('data:' + this.tmpURL);
this.signature = this.signaturePad.fromDataURL(this.tmpURL);

}
`

Hi,

Is there any solution for multiple signature under this pad?
How to change following code for multiple signature? I tried many possibility with no luck.
@ViewChild(SignaturePad) signaturePad: SignaturePad;

Find the length of signature in canvas(angular2-signaturepad) ?

 <signature-pad [options]="signaturePadOptions"
                  (onEndEvent)="drawComplete()">
      </signature-pad>//html code

drawComplete() {
   signaturePad.toData()[0].length //get length 
 }//js code

Hi I wanted to know how can we center the image on the canvas we drew using this method :
signaturePad.fromDataURL(base64_image_data);

Hi,

I have existing ionic2 project, and tried to add angular2-signaturepad.

I installed it via npm. I edited config file like below.

      commonjs({
          include: [
            'node_modules/rxjs/**',
            'node_modules/angular2-signaturepad/**'
          ],
          namedExports: {
            'node_modules/angular2-signaturepad/signature-pad.js': ['SignaturePadModule']
          }
        }

How ever, when I import it from app.module.ts even without doing anything, I get

signature_pad.js:13Uncaught TypeError: Cannot set property 'SignaturePad' of undefined
Error, and it's pointing

root['SignaturePad'] = factory();

line. If it's relevant I use

"@ionic/app-scripts": "^0.0.36",
"typescript": "^2.0.3"

I appreciate for any help.

Thank you.

Hello - i am trying to implement your demo and i get this error upon running. i've tried using this demo as well as the simpler version on the main git hub page and get the same error.

SignatureFieldComponent class SignatureFieldComponent - inline template:0:0 caused by: sp is not a constructor
Error: Error in ./SignatureFieldComponent class SignatureFieldComponent - inline template:0:0 caused by: sp is not a constructor

I saw on your demo that it's possible to sign over an image, but the saved image contains the signature only. Is there a way to save both as a single image file?
