Signature background image

jefjeffjefff commented 2 years ago

Hi! I'm amazed and thankful on how you have built this library, but I have one question.

Is there a way to include the background image on readSignature?

Thank you in advance.

you can use dataURL prop as background image, need a base64 img

@YanYuanFE I can't load a previous drawing using dataURL prop (no errors, just a blank canvas). Please, could you check what is wrong on my code? Thank you so much.

"react": "17.0.2", "react-native": "0.67.2", "react-native-signature-canvas": "^4.3.0",

import React, {memo} from 'react';
import {StyleSheet, View} from 'react-native';
import SignatureScreen from 'react-native-signature-canvas';

const AreaEscrita = props => {
  const {onRef, onOK, onGetData, onDataURL, webStyle} = props;
  console.log(onDataURL);

  const altura = '100px';
  const style = `.m-signature-pad--footer {display: none; margin: 0px;}
  .m-signature-pad {  height: ${altura};padding:0px; margin:0px;`; //para não ter botões

  return (
    <View style={styles.container}>
      <SignatureScreen
        ref={onRef} //ref do react (hook)
        onOK={onOK} //manipula quando manda salvar
        onGetData={onGetData}
        dataURL={onDataURL}
        webStyle={webStyle ? webStyle : style}
        penColor={props.penColor}
        bgSrc={props.bgSrc ? props.bgSrc.uri : ''}
        bgHeight={props.bgHeight ? props.bgHeight : null}
        bgWidth={props.bgWidth ? props.bgWidth : null}
        onBegin={props.onBegin ? props.onBegin : undefined} 
        onEnd={props.onEnd} 
        minWidth={2}
      />
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 4,
    alignItems: 'center',
    justifyContent: 'center',
    padding: 0, //10
    zIndex: -1,
  }
});

export default memo(AreaEscrita);

I have tested the base64 on https://base64.guru/converter/decode/image and the output is ok.

dataURL works fine, but since your image is originally white with only a black dot on it, it doesn't seem to work, you can try the following URL。 const url =

Thank you for your support, guys @YanYuanFE and @jefjeffjefff . I don't know why, but in "react": "17.0.2" and "react-native": "0.67.2" I think it's necessary force a re-render to show dataURL. I have solved putting the variable such as state and initialize it in a useEffect. Now, it works fine. Thanks!
