This is a beautiful image. I'm wondering how it can 开发者_如何学Pythonbe generated programmatically with an image-processing library like imagemagick or gd?

My general idea is that the frame itself could be defined separately, but is there way to fill that frame with letters in the same way they're doing it here but programmatically?

CSS has nothing to do with image-generation, just presentation of DOM elements--if you want to create it in an HTML/DOM window, you could do such, but if you're looking to actually generate an image via PHP, ImageMagick is generally route people go (though you'll need ImageMagick installed on the server).

The best approach would probably be entirely server side (i.e. with php or you language of choice). The other option would be entirely client side, that is, with Javascript and CSS - here you would need each letter to be absolutely positioned, and there would likely be a bit of performance overhead.

I'm not quite clear what you're asking. "Filling the frame" can be pretty easily done by using a mask. Most graphic platforms support this, on the server (gd, image magick) or on the client (flash, html canvas).

If you're asking how to programmatically create one of these, this is going to be slightly more complicated ;)
