npm install react-native-image-pixel
Allows to get RGBA pixel data from a local raster image file
``sh`
npm install react-native-image-pixel
or
`sh`
yarn add react-native-image-pixel
`js
import * as RNImagePixel from 'react-native-image-pixel';
// ...
const IMAGE_FILE_PATH = '/some/local/path/image.png';
// loading image
const {id, width, height} = await loadImage(IMAGE_FILE_PATH);
// ...
const normalized = true; // flag value that points if x and y are in the range of [0...width] and [0...height] respectively (for non-normalized) or [0...1] (for normalized)
let x = 100;
let y = 100;
if(normalized) {
x /= width;
y /= height;
}
// getting pixel color components (r,g,b,a) and hex representation string (hex)
const {r, g, b, a, hex} = await getPixel(id, x, y, normalized);
// ...
// unloading image
await unloadImage(id);
