You can also throttle the resize event - you can find some examples on this MDN page. ![]() Instead of resize event you can listen to screen orientation change, if you're using this library only on mobile devices. addEventListener ( "resize", resizeCanvas ) resizeCanvas ( ) fromData ( data ) // Draws signature image from an array of point groups, without clearing your existing image (clear defaults to true if not provided) signaturePad. ![]() toData ( ) // Draws signature image from an array of point groups signaturePad. fromDataURL ( "data:image/png base64,iVBORw0K." ) // Returns signature image as an array of point groups const data = signaturePad. Thus, after using #fromDataURL, #toData won't work properly. NOTE: This method does not populate internal data structure that represents drawn signature. toDataURL ( "image/svg+xml" ) // save image as SVG // Draws signature image from data URL. toDataURL ( "image/jpeg" ) // save image as JPEG signaturePad. toDataURL ( ) // save image as PNG signaturePad. querySelector ( "canvas" ) const signaturePad = new SignaturePad ( canvas ) // Returns signature image as data URL (see for the list of possible parameters) signaturePad.
