import React, { Component } from 'react';

class ImageBorder extends Component

{

    render(

      View style={styles.container}

             Image style ={styles.imageStyle}  source={require('./img/xxxxxxx.png')}

     View

    )

    {

    return (

    )

    };

};

const styles = StyleSheet.create({

    container: {

    backgroundColor:'red',

    borderTopLeftRadius:20,

    overflow:'hidden',

    height: 200,

    marginLeft:100,

    width: 200,
