Code Snippet: Resizing Images with JavaScript

Here’s an example code snippet that demonstrates how to resize images using JavaScript and the HTML5 canvas element:

// Get the canvas element

var canvas = document.getElementById("canvas");

var ctx = canvas.getContext("2d");



// Get the image element

var image = document.getElementById("image");



// Set the image source

image.src = "image.jpg";



// Resize the image

function resizeImage() {

  var width = 800;

  var height = 600;

  var ratio = width / height;

  var newWidth = width * ratio;

  var newHeight = height * ratio;

  ctx.drawImage(image, 0, 0, newWidth, newHeight);

}



// Add an event listener to the canvas

canvas.addEventListener("click", resizeImage);



// Add an event listener to the image

image.addEventListener("click", function() {

  resizeImage();

});

This code snippet demonstrates how to resize an image using the HTML5 canvas element and JavaScript. It sets the image source, resizes the image, and adds an event listener to the canvas and image elements to trigger the resizing process when the canvas or image is clicked.
