The Precision Xtra lets you receive mouse events on a pixel level. By associating a color map with a region on the stage, you can give each of 256 different map colors the power to respond to up to eleven different mouse events. An easy to use authoring tool lets you assign most any action you want. And you can use multiple maps for tens of thousands of unique pixels.
Usage is simple.
You make a 256-color color map, with a different color for each area that your want to differentiate. You then insert the Xtra into the cast and then use the Precision Xtra Authoring Tool to enable the different colors to respond to various events, like mouseEnter or mouseUp. Place the Xtra instance on the stage and it will absorb events for the region it covers. It could be over a single image, like a RGB photograph, or a variety of sprites. You can place multiple versions on the stage to differentiate between literally tens of thousands of individual pixels.
