React Native Get Pixel
Returns the pixel color from an image at a given coordinate. Heavily inspired by https://github.com/spacesuitdiver/react-native-pixel-color
Setup
yarn add react-native-get-pixel
react-native link react-native-get-pixel
Android
Note: on latest versions of React Native, you may have an error during the Gradle build on Android (com.android.dex.DexException: Multiple dex files define Landroid/support/v7/appcompat/R$anim
). Run cd android && ./gradlew clean
to fix this.
Usage example
import { getPixelRGBA } from 'react-native-get-pixel';
getPixelRGBA('sample.png', x, y)
.then(color => console.log(color)) // [243, 123, 0]
.catch(err => {});
NOTE: You have to add sample.png to the Xcode project as a resource and to src/main/assets/drawable
on Android.
