6 min readTo load an image into a canvas, you first need to create a new Image object in JavaScript. Then, assign the source URL of the image you want to load to the "src" attribute of the Image object. Once the image is loaded, you can draw it onto the canvas using the canvas' context object and the drawImage() method. Make sure to wait for the image to fully load before attempting to draw it onto the canvas to avoid any issues with the image not displaying properly.

7 min readTo draw an SVG on top of a canvas, you can use the drawImage() method in the canvas API. First, you need to create an image element and set its source to the SVG file. Then, use the drawImage() method to draw the image on the canvas at the desired position. Make sure to load the image before drawing it on the canvas to ensure it is rendered correctly. Additionally, you can use CSS positioning to overlay the SVG on top of the canvas for more control over its placement.

4 min readTo test canvas using Selenium, you can use the Actions class to simulate mouse interactions on the canvas element. You can create mouse movements, clicks, drags, and other actions to interact with the canvas. You can also verify the canvas content by capturing screenshots before and after performing actions on the canvas, and comparing them to detect any changes. It is important to handle canvas elements with care as they may require different handling than regular HTML elements.

5 min readTo overlap shapes on top of each other in canvas, you can first draw one shape using the canvas drawing methods, and then draw another shape on top of it. You can control the order in which shapes are drawn by the sequence in which you call the drawing methods. Shapes drawn later will appear on top of shapes drawn earlier. This allows you to create complex designs by layering multiple shapes on top of each other.

3 min readTo draw two images with style in canvas, you can begin by loading the images using the HTMLImageElement object. Once the images are loaded, you can use the drawImage() method to draw them on the canvas. You can apply different styles to the images by setting properties such as opacity, rotation, scaling, and positioning. For example, you can use the globalAlpha property to adjust the transparency of the images, or the rotate() method to rotate them.

3 min readTo draw xlink:href to a canvas using HTML5, you can use the drawImage() method in conjunction with the new Image() object. First, create a new Image object and set its src attribute to the xlink:href value. Once the image is loaded, use the drawImage() method to draw the image on the canvas at the desired position. Make sure to handle any loading errors or exceptions that may occur during the process.

6 min readTo get the actual size of an image in a canvas, you can use the naturalWidth and naturalHeight properties of the image object. These properties return the intrinsic width and height of the image, which is the original size of the image before any resizing or scaling in the canvas. You can access these properties like this: const image = new Image(); image.src = 'example.jpg'; image.onload = function() { const actualWidth = image.naturalWidth; const actualHeight = image.
