Hey @tougbia09,

I'm sorry to read that you're frustrated. react-native-canvas is a project by people for free on their free time. We always seek to enhance it and put a lot of effort for this but unfortunately it is still far from perfect.

I do expect comments to use respectful language and users to understand that we're doing our best.

The circle to the right is an actual image, while there should be a rendered one to the left which apparently it doesn't work. It is a known issue but it has nothing to do with resolution

[iddan]

I was able to reproduce the resolution problem and plan to fix it in the near future.

Fixed at version 0.1.11

[tougbia09]

just updated to 0.1.11 and 0.1.14. Then nothing works anymore , Blank canvas. Missed something ?

[iddan]

Can you please provide more details?

[tougbia09]

import React from 'react';
import Canvas,{Image as CanvasImage, Path2D} from 'react-native-canvas';
import {StatusBar, StyleSheet, Text, View } from 'react-native';

export default class App extends React.Component {
handleCanvas = (canvas) => {
canvas.width = 300;
canvas.height = 300;
const ctx = canvas.getContext('2d');
ctx.fillStyle = 'purple';
ctx.fillRect(0, 0, 100, 100);
}
render() {
return (
<Canvas ref={this.handleCanvas}/>
)
}
}

android 6.0

And which device were you trying this on?

[tougbia09]

INFINIX HOT S . But I think that its caused by a weird scroll which appear ! it behaves like a embded
webview. Have a look the screenshot (android emulator samsung s7 - 6.0)

For me the latest version works well on Android 6.0 emulator (on a Nexus One like emulator). Will try this device.
