Textorizer
I have stumble upon a site called Textorizer (http://textorizer.whatfettle.com). Do you know what textorizer is? Textorizer takes a raster image in a format such as png, jpeg or gif, detects edges using a Sobel convolution filter and replaces them with supplied lines of text. The output from textorizer is in SVG, which can be viewed directly in the Firefox 1.5 browser or using the Adobe SVG Plugin. It is a C extension to PHP, and released under the W3C software license. Sound great right?
