HTML canvas provides us with a set of tools we can use to scan any image, get information about pixels that make up that image such as their color values and coordinates and then we can use those values to create all different kinds of effects from a simple colour shift or grayscale to advanced particle system effects like this. In todays episode we will dive deep into 3 important canvas methods drawImage, getImageData and putImageData.

I've created this simple HTML canvas tutorial for beginners to help you get full understanding of what exactly they do so we can take that to the next level. All of that with no frameworks and no libraries using just plain vanilla JavaScript, as usual. Welcome to my creative coding series.
