I am complete beginner in react konva. I am using Image component with the use-image hook to display a picture but I want the picture to be round. I tried different css approach but nothing seems to work. Any Help is much appreciated
import picture from "../assets/pic.jpg";
const [image] = useImage(picture);
<Stage>
<Layer><Image borderRadius="50%" image={image} /></Layer>
</Stage>
Konva.Image
doesn't have border radius property. It is not a DOM element, so you can't apply CSS styles to it.
You can emulate border radius effect with group clipping.
const RoundedImage = ({}) => {
const [image] = useImage("http://konvajs.github.io/assets/darth-vader.jpg");
return (
<Group
clipFunc={(ctx) => {
const cornerRadius = 20;
const width = image ? image.width : 0;
const height = image ? image.height : 0;
ctx.beginPath();
ctx.moveTo(cornerRadius, 0);
ctx.lineTo(width - cornerRadius, 0);
ctx.quadraticCurveTo(width, 0, width, cornerRadius);
ctx.lineTo(width, height - cornerRadius);
ctx.quadraticCurveTo(width, height, width - cornerRadius, height);
ctx.lineTo(cornerRadius, height);
ctx.quadraticCurveTo(0, height, 0, height - cornerRadius);
ctx.lineTo(0, cornerRadius);
ctx.quadraticCurveTo(0, 0, cornerRadius, 0);
ctx.closePath();
}}
>
<Image image={image} />
</Group>
);
};
