Using the suckah object
Suckah can be used much like the eyedropper tool in photoshop to grab the current color value of any screen pixel. This is useful in creating color palates from images, chromakeying, color tracking, UI design, and more.
- Jitter Tutorial 10: Chromakeying, introduces the application of suckah in chromakeying. The suckah object sits on top of the pwindow displaying the source video, allowing you to click directly on the color you want to key out.
- Jitter Tutorial 25: Tracking the Position of a Color in a Movie, offers a method of combining suckah with the jit.findbounds object to track colored objects. Note that this functionality is not built in to the tutorial patch, but is in the text portion of the tutorial reference.
