Html5 Canvas Translate(0.5,0.5) Not Fixing Line Blurryness

Reading related articles, I've tried forcing the canvas size in pixels, specifying half pixels for the paths and also context.translate(0.5) but my canvas lines are still blurry. S

Solution 1:

Retina & HiDPI devices

Looking at the image you supplied. The canvas is half the resolution of the display. Zoom in and look at the pixels on the "X", The DOM line is 1px yet still twice a wide as the pixels on that letter. That means the canvas is being stretched and the blur is due to the bilinear filtering. Either you are zoomed out on the tab or you have a retina or HiDPI display. Set the canvas.width & canvas.height to twice what it is, set the canvas.style.width & canvas.style.height to DOM pixels. Remove the ctx.translate and add ctx.scale(2,2) and all things will be clear.
