Microsoft
ClearType is good software. It's a font rendering option in
Windows XP that makes things look better on LCDs. Between laptops and
good
desktop LCDs a lot of folks have LCDs. So go ahead,
turn on ClearType!
And get
the tuner while you're at it.
The technology is surprisingly
straightforward. LCDs are made up of lots of tiny red, green, and
blue pixels. ClearType uses that structure by doing subpixel rendering
of fonts, so instead of drawing a white pixel where you'd expect it
draws a blue pixel next to a yellow one, which still looks white. You
can see it above in the colour fringing; at normal resolution on the
LCD it looks right. It reminds me of the old Apple ][ colour
hack where they fit 6 colours per pixel in 1.14 bits.
Microsoft's implementation is quite robust. I was particularly impressed when I rotated my LCD 90 degrees and it still did ClearType, only in the Y axis. Still, Windows typography has a way to go. Apple's font rendering is still head and shoulders above anyone else's. I'd love to read an article that explains exactly why text looks so beautiful on a 12" Powerbook. |
