I don't agree, though. I wouldn't expect a screen capture to be binary just because text was being displayed. In fact, I would never capture or scan text to binary if I had the option otherwise. Screen captures of text on my Windows laptop look just as good as the original. Nomee—Thanks for your comments. I don’t agree, though.

However capturing screen text and storing might become an issue. You capture a text field which was suppose to be a binary image however when you store it in paint or some other imaging software you see it as an RGB which may not look as crisp and even readable when converted to grayscale.

I'm going to add your subpixel rendering link to the post. Alessandro—Thanks. I’m going to add your subpixel rendering link to the post.

I agree that's extremely cool: have a look at http://en.wikipedia.org/wiki/Subpixel_rendering Typography is also something deeply fascinating...
