Cannot resize an SVG image in React Native app

Question

I have the following React Native project:

https://snack.expo.io/BkBU8fAlV

where I have the following code:

import * as React from 'react';
import { Text, View, StyleSheet } from 'react-native';
import { Constants } from 'expo';

// You can import from local files
import AssetExample from './components/AssetExample';

// or any pure javascript modules available in npm
import { Card } from 'react-native-paper';

import HomerSvg from './assets/HomerSvg';

export default class App extends React.Component {
  render() {
    return (
      <View style={styles.container}>
        <Text style={styles.paragraph}>
          Change code in the editor and watch it change on your phone! Save to get a shareable url.
        </Text>
        <View style={{ width: 80, height: 80 }}>
          <HomerSvg />
        </View>
        <Card>
          <AssetExample />
        </Card>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    paddingTop: Constants.statusBarHeight,
    backgroundColor: '#ecf0f1',
    padding: 8,
  },
  paragraph: {
    margin: 24,
    fontSize: 18,
    fontWeight: 'bold',
    textAlign: 'center',
  },
});

I display the SVG image through the component: HomerSvg which uses the react-native-svg package.

What I need is to resize somehow the SVG image. On the code above I did a try with no success.

I tried by giving the container view some width and height with no success.

Do you have any idea on how can I achieve that?

Thanks!

Answer 1

You can wrap all the <Path /> elements inside a <G /> and scale the <G /> component by calculating the scale factor using Dimensions i.e width and height of the device.

<G transform="scale(scaleFactor) translate(offsetX,offsetY)>
<Path/>
<Path/>
.
.
.
<G/>

where scaleFactor, offsetX and offsetY can be calculated via const { height, width } = Dimensions.get("window")
