I’ve been curious about subpixel rendering lately, and trying to figure out why, when you zoom in on a bitmapped text character, instead of black and white, it shows up with blue, maroon, goldenrod and all sorts of weird colors. Steve Gibson explains the theory of subpixel rendering and the implementation. In my setup, there’s a magnified 400% image of 4 of the character “A”, from straight whole-pixel black and white, then on-off subpixels, then with the color-balanced algorithm run once, and twice. The rightmost set of “A” is rendered using Microsoft’s built-in subpixel rendering system “ClearType”.
