Once you have set up the canvas, you can start drawing on it using various methods. Here is an example of how to draw a rectangle:
// Get the drawing context
var ctx = canvas.getContext(“2d”);// Draw a rectangle
ctx.fillStyle = “#FF0000”;
ctx.fillRect(0, 0, 150, 75);
The above code will draw a red rectangle with a width of 150 pixels and height of 75 pixels. You can experiment with different colors, shapes, and sizes to create your desired graphics.
Adding Text to the Canvas
You can also add text to the canvas using the following code:
// Get the drawing context
var ctx = canvas.getContext(“2d”);// Add text
ctx.font = “30px Arial”;
ctx.fillStyle = “blue”;
ctx.fillText(“Hello World”, 10, 50);
The above code will add the text “Hello World” to the canvas in blue color and with a font size of 30 pixels.
