| Using scriptable masks Description This sample covers how to dynamically mask Flash content at runtime using scriptable masks and components. Scriptable masking allows precise control over how masks behave at runtime, and allows the mask and/or the masked content to be dynamically changed at runtime. This sample shows different types of masks and masked content that are controlled by a user interface built with components. Explore this sample to learn more about masking and building interfaces with components.
