Image Editor Native module for React Native.
Originally extracted from React Native issue#23313 and maintained by the community.
``shell`
yarn add @react-native-community/image-editoror
npm install @react-native-community/image-editor --save
`shell`
npx pod-install
Start by importing the library:
`ts`
import ImageEditor from '@react-native-community/image-editor';
Crop the image specified by the URI param. If URI points to a remote image, it will be downloaded automatically. If the image cannot be loaded/downloaded, the promise will be rejected.
If the cropping process is successful, the resultant cropped image will be stored in the cache path, and the CropResult returned in the promise will point to the image in the cache path. ⚠️ Remember to delete the cropped image from the cache path when you are done with it.
`ts`
ImageEditor.cropImage(uri, cropData).then((result) => {
console.log('Cropped image uri:', result.uri);
});
