rn-get-pixel

React Native Get Pixel

(fork of react-native-pixel-color with remote images enabled)

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.
