Usage example 1 (using the default footer)
import React, { Component } from 'react';
import { Platform, ImageStore } from 'react-native';
import { Actions } from 'react-native-router-flux';
import AmazingCropper from 'react-native-amazing-cropper';;
class AmazingCropperPage extends Component {
onDone = (croppedImageUri) => {
console.log('croppedImageUri = ', croppedImageUri);
if (Platform.OS === 'ios') {
ImageStore.getBase64ForTag(
croppedImageUri,
(base64Image) => {
// send image to server or save it locally
ImageStore.removeImageForTag(croppedImageUri);
},
(err) => {}
);
}
else {
// send image to server
}
// navigate to the next page of your application
Actions.home();
}
onCancel = () => {
// navigate back
Actions.pop();
}
render() {
return (
<AmazingCropper
onDone={this.onDone}
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 { Platform, ImageStore } from 'react-native';
import { Actions } from 'react-native-router-flux';
import AmazingCropper, { DefaultFooter } from 'react-native-amazing-cropper';
class AmazingCropperPage extends Component {
onDone = (croppedImageUri) => {
console.log('croppedImageUri = ', croppedImageUri);
if (Platform.OS === 'ios') {
ImageStore.getBase64ForTag(
croppedImageUri,
(base64Image) => {
// send image to server or save it locally
ImageStore.removeImageForTag(croppedImageUri);
},
(err) => {}
);
}
else {
// send image to server
}
// navigate to the next page of your application
Actions.home();
}
onCancel = () => {
// navigate back
Actions.pop();
}
render() {
return (
<AmazingCropper
// Pass custom text to the default footer
footerComponent={<DefaultFooter doneText='OK' rotateText='ROT' cancelText='BACK' />}
onDone={this.onDone}
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 { Platform, ImageStore } from 'react-native';
import { Actions } from 'react-native-router-flux';
import AmazingCropper from 'react-native-amazing-cropper';
import CustomCropperFooter from './src/components/CustomCropperFooter.component';
class AmazingCropperPage extends Component {
onDone = (croppedImageUri) => {
console.log('croppedImageUri = ', croppedImageUri);
if (Platform.OS === 'ios') {
ImageStore.getBase64ForTag(
croppedImageUri,
(base64Image) => {
// send image to server or save it locally
ImageStore.removeImageForTag(croppedImageUri);
},
(err) => {}
);
}
else {
// send image to server
}
// navigate to the next page of your application
Actions.home();
}
onCancel = () => {
// navigate back
Actions.pop();
}
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}
onCancel={this.onCancel}
imageUri='https://www.lifeofpix.com/wp-content/uploads/2018/09/manhattan_-11-1600x2396.jpg'
imageWidth={1600}
imageHeight={2396}
/>
);
}
}
