Sub-pixel rendering in Chrome Canvas

Question

I\'m wondering if anyone knows if it\'s possible to enable sub-pixel rendering in an HTML5 canvas in Chrome (and/or Safari).

Chrome does sub-pixel rendering in HTML,

Answer 1

I don't believe this is possible presently.

It's a hard problem because canvas provides so much low-level control to the user. If canvas starts doing intelligent things like this, it may break some other functionality the user was expecting.

Consider the subpixel rendering for other graphical elements - depending on the application, the programmer may not want that, and you certainly wouldn't want subpixel rendering turned on arbitrarily for the whole element as an all-or-nothing proposition. Imagine getting the color of a specific pixel - what's the right answer here? Should canvas lie and return the expected color, or return the actual color (so we have to answer questions all day here on SO about "why is this pixel I made black being measured as dark red?").

There are some who would argue that Firefox is doing the wrong thing here.
