Pixelmator is the sweet app for Mac that gives you great photo editing capabilities. It’s a minor update, but it adds text effects through “convert text to shape.”
This apparently makes it easier to add various color effects to text, down to individual letters. What’s particularly interesting is that it vectorizes the letters. This means you can bend and shape the letters with the supplied tools.
You can check out the preview video of Pixelmator 2.2 here.
The latest update is not yet available, but it should hit the Mac App Store in the near future.
