Image react native

Adding Image
Let us create a new folder img inside the src folder. We will add our image (myImage.png) inside this folder.

We will show images on the home screen.

App.js
import React from 'react';
import ImagesExample from './ImagesExample.js'

const App = () => {
   return (
      <ImagesExample />
   )
}
export default App
Local image can be accessed using the following syntax.

image_example.js
import React, { Component } from 'react'
import { Image } from 'react-native'

const ImagesExample = () => (
   <Image source = {require('C:/Users/Tutorialspoint/Desktop/NativeReactSample/logo.png')} />
)
export default ImagesExample

react native asign width to image

First import Dimensions from react-native

import { Dimensions } from 'react-native';
then you have to get the dimensions of the window

const win = Dimensions.get('window');
Now calculate ratio as

const ratio = win.width/541; //541 is actual image width
now the add style to your image as

imageStyle: {
    width: win.width,
    height: 362 * ratio, //362 is actual height of image
}
