I was wondering how Matt made the titles of his posts appear so perfect and I realized that they were PNG (portable network graphics or simple picture files) files. So I started looking for ways to convert text into PNG automagically using PHP. This would enable all kinds of freaky fonts, colors and other magic to be used with inline text. I came up with this wonderful article from NewtNotes which explains the process of creating PNG files from TTF fonts using PHP and even provides source code. Here is the link to the tutorial.
I blog this so when inspiration strikes, I can whip up some code myself!
