react-native-amazing-cropper

Image cropper for react native made with Animated API (with rotation possibility) - for iOS & android

NEW: This library was rewritten in Typescript. I am new to typescript, so if you have suggestions, PR's are welcome.

    
    

    
    

This component depend on react-native-image-rotate and @react-native-community/image-editor libraries. They need to be installed and linked to your project before.

STEPS TO INSTALL:
1.* npm install --save react-native-image-rotate @react-native-community/image-editor
2. react-native link react-native-image-rotate @react-native-community/image-editor
3.* npm install --save react-native-amazing-cropper

Step 2 is not needed for react-native >= 0.60 because of autolinking. Instead run pod install inside ios directory.

Usage example 1 (using the default footer)

import React, { Component } from 'react';
import AmazingCropper from 'react-native-amazing-cropper';;

class AmazingCropperPage extends Component {
  onDone = (croppedImageUri) => {
    console.log('croppedImageUri = ', croppedImageUri);
    // send image to server for example
  }

  onError = (err) => {
    console.log(err);
  }

  onCancel = () => {
    console.log('Cancel button was pressed');
    // navigate back
  }

  render() {
    return (
      <AmazingCropper
        onDone={this.onDone}
        onError={this.onError}
        onCancel={this.onCancel}
        imageUri='https://www.lifeofpix.com/wp-content/uploads/2018/09/manhattan_-11-1600x2396.jpg'
        imageWidth={1600}
        imageHeight={2396}
        NOT_SELECTED_AREA_OPACITY={0.3}
        BORDER_WIDTH={20}
      />
    );
  }
}

Usage example 2 (using the default footer with custom text)

---

import React, { Component } from 'react';
import AmazingCropper, { DefaultFooter } from 'react-native-amazing-cropper';

class AmazingCropperPage extends Component {
  onDone = (croppedImageUri) => {
    console.log('croppedImageUri = ', croppedImageUri);
    // send image to server for example
  }

  onError = (err) => {
    console.log(err);
  }

  onCancel = () => {
    console.log('Cancel button was pressed');
    // navigate back
  }

  render() {
    return (
      <AmazingCropper
        // Pass custom text to the default footer
        footerComponent={<DefaultFooter doneText='OK' rotateText='ROT' cancelText='BACK' />}
        onDone={this.onDone}
        onError={this.onError}
        onCancel={this.onCancel}
        imageUri='https://www.lifeofpix.com/wp-content/uploads/2018/09/manhattan_-11-1600x2396.jpg'
        imageWidth={1600}
        imageHeight={2396}
      />
    );
  }
}

Usage example 3 (using own fully customized footer)

---

Write your custom footer component.
Don't forget to call the props.onDone, props.onRotate and props.onCancel methods inside it (the Cropper will pass them automatically to your footer component). Example of custom footer component:

import React from 'react';
import { View, TouchableOpacity, Text, Platform, StyleSheet } from 'react-native';
import PropTypes from 'prop-types';
import MaterialCommunityIcon from 'react-native-vector-icons/MaterialCommunityIcons';

const CustomCropperFooter = (props) => (
  <View style={styles.buttonsContainer}>
    <TouchableOpacity onPress={props.onCancel} style={styles.touchable}>
      <Text style={styles.text}>CANCEL</Text>
    </TouchableOpacity>
    <TouchableOpacity onPress={props.onRotate} style={styles.touchable}>
      <MaterialCommunityIcon name='format-rotate-90' style={styles.rotateIcon} />
    </TouchableOpacity>
    <TouchableOpacity onPress={props.onDone} style={styles.touchable}>
      <Text style={styles.text}>DONE</Text>
    </TouchableOpacity>
  </View>
)

export default CustomCropperFooter;

CustomCropperFooter.propTypes = {
  onDone: PropTypes.func,
  onRotate: PropTypes.func,
  onCancel: PropTypes.func
}

const styles = StyleSheet.create({
  buttonsContainer: {
    flexDirection: 'row',
    alignItems: 'center', // 'flex-start'
    justifyContent: 'space-between',
    height: '100%'
  },
  text: {
    color: 'white',
    fontSize: 16
  },
  touchable: {
    padding: 10,
  },
  rotateIcon: {
    color: 'white',
    fontSize: 26,
    ...Platform.select({
      android: {
        textShadowOffset: { width: 1, height: 1 },
        textShadowColor: '#000000',
        textShadowRadius: 3,
        shadowOpacity: 0.9,
        elevation: 1
      },
      ios: {
        shadowOffset: { width: 1, height: 1 },
        shadowColor: '#000000',
        shadowRadius: 3,
        shadowOpacity: 0.9
      }
    }),
  },
})

Now just pass your footer component to the Cropper like here:

import React, { Component } from 'react';
import AmazingCropper from 'react-native-amazing-cropper';
import CustomCropperFooter from './src/components/CustomCropperFooter.component';

class AmazingCropperPage extends Component {
  onDone = (croppedImageUri) => {
    console.log('croppedImageUri = ', croppedImageUri);
    // send image to server for example
  }

  onError = (err) => {
    console.log(err);
  }

  onCancel = () => {
    console.log('Cancel button was pressed');
    // navigate back
  }

  render() {
    return (
      <AmazingCropper
        // Use your custom footer component
        // Do NOT pass onDone, onRotate and onCancel to the footer component, the Cropper will do it for you
        footerComponent={<CustomCropperFooter />}
        onDone={this.onDone}
        onError={this.onError}
        onCancel={this.onCancel}
        imageUri='https://www.lifeofpix.com/wp-content/uploads/2018/09/manhattan_-11-1600x2396.jpg'
        imageWidth={1600}
        imageHeight={2396}
      />
    );
  }
}
