typeface.js
With typeface.js you can embed custom fonts in your web pages so you don't have to render text to images.
NEW! Version 0.15 is released, now with support for Internet Explorer 9.
typeface.js is easy...
Instead of creating images or using flash just to show your site's graphic text in the font you want, you can use typeface.js and write in plain HTML and CSS, just as if your visitors had the font installed locally. Here's what it takes to get going: load the typeface.js library and some typeface.js fonts, then proceed like normal:
<script src="typeface-0.15.js"></script>
<script src="helvetiker_regular.typeface.js"></script>

<div class="typeface-js" style="font-family: Helvetiker">
Text here in Helvetiker font...
</div>
open source...
You're encouraged to make a donation to this project if you find typeface.js helpful. This code is and always will be free and open source. This includes both the typeface.js javascript library, as well as the perl module with functionality to convert truetype fonts to typeface ones.
cross-platform...
Supported browsers include Firefox 1.5+, Safari 2+, and Internet Explorer 6+. Things will degrade gracefully for other browsers. Users browsing with their PDA's, for example, will still see your text there--it just won't be quite as pretty. Search engines will see your graphic text now too, without having to rely on OCR or "alt" properties.
flexible...
The CSS2 specification includes directives for defining many aspects of text layout, but browsers' implementations have been spotty. This library aims to fill in the gaps. Notably, there's support for the 'font-stretch' property as well as finer-grained control with 'letter-spacing' and others. see examples »
limited...
There's room yet for improvement and optimization. Performance is fairly good for usage with page titles and headings for instance, but you'll probably find using typeface.js for body text to be too slow. Also, implementation is missing for the :hover CSS psuedo-selector, and there are probably all sorts of other shortcomings.
