Canvas Java

Canvas component for Vaadin 10+

This is a Java integration of the HTML5 <canvas> for Vaadin Platform.

It provides a subset of the client-side JavaScript API to Java users.

Sample code

Canvas canvas = new Canvas(800, 500);
CanvasRenderingContext2D ctx = canvas.getContext();

// Draw a red line from point (10,10) to (100,100):
ctx.setStrokeStyle("red");
ctx.beginPath();
ctx.moveTo(10, 10);
ctx.lineTo(100, 100);
ctx.closePath();
ctx.stroke();

// Draw an image located in src/main/webapp/resources:
ctx.drawImage("resources/vaadin-logo.svg", 0, 0));
