The “knowledge” is applied when the text is rendered to the bitmap, not when the bitmap is pushed to the display. You’d be right if the effect happened quite late in the rendering process. It doesn’t — it happens really early.
- rl3 8y agoScreenshots aren't very useful for meets-the-eye visual quality comparisons of subpixel AA unless your display has the same pixel arrangement and resolution as the display the screenshot was rendered on. Even then, there's probably other issues. I agree that they work for technical comparisons of rendered output.
- pvg 8y agoMaybe I'm confused about something then but you seem to be telling me the subpixel AA is positionally independent. I can take the subpixel AA-ed bitmap and plop it in a page, open it on some other browser and OS and be certain everything is the same down to each coloured subpixel. You'd think every, say, vertical line would have the same colour artifacting, if that were the case. But they don't.
- ubercow13 8y agoThey do? They're just coloured pixels. When you open a bitmap image on different PCs and screens and display it at 1x wrt the monitor's pixels, you would expect every pixel to have the same colour across every PC/screen, no?
- czr 8y agoThe pixels will be the same on every PC/screen. The perceived sharpness/blurriness won't be–the whole point of the "color fringing" is that the subpixels of any particular display have an arrangement that can be exploited to add additional sharpness: https://upload.wikimedia.org/wikipedia/commons/0/0f/Antialias-vrs-Cromapixel.svg https://upload.wikimedia.org/wikipedia/commons/0/0f/Antialia... If the display you're viewing the image on has a different subpixel layout than the one that the image was rendered for, it won't look sharper.
