I'm playing around with the <canvas> element, drawing lines and such.
I've noticed that my diagonal lines are antialiased. I'd prefer the jaggy look for what I'm doing - is there any way of turning this feature off?

However, the Canvas still looks pixelated. This is because the Canvas is rendering to a bitmap of one size then scaling the bitmap to fit the CSS dimensions. To fix this, we modify the Canvas's bitmap dimensions to match the CSS dimensions using JavaScript.
The HTML <canvas> element is used to draw graphics, on the fly, via JavaScript. The <canvas> element is only a container for graphics.
<canvas> is an HTML element which can be used to draw graphics via scripting (usually JavaScript). This can, for instance, be used to draw graphs, combine photos, or create simple animations.
Canvas Is Useful Even if You Never Planned to Use Flash The CANVAS element allows you to add so much more interactivity to your web pages because now you can control the graphics, images, and text dynamically with a scripting language.
Draw your 1-pixel lines on coordinates like ctx.lineTo(10.5, 10.5). Drawing a one-pixel line over the point (10, 10) means, that this 1 pixel at that position reaches from 9.5 to 10.5 which results in two lines that get drawn on the canvas.
A nice trick to not always need to add the 0.5 to the actual coordinate you want to draw over if you've got a lot of one-pixel lines, is to ctx.translate(0.5, 0.5) your whole canvas at the beginning.
