2. Masking Any object can be used to mask another object. The opacity and lightness of the mask determines the opacity of the masked objects. A masked object will be fully opaque only at places that are: inside the mask path, where the mask has maximum lightness (i.e., white), and the mask has maximum Alpha. So to summarize: Regions with minimum lightness (i.e., black) will be fully transparent. Regions with minimum Alpha (zero alpha) will be fully transparent. Regions outside the mask will be fully transparent.All this sounds complex but in action it is quite simple: For example if you place a white circle over a bitmap image and then set the circle to mask the image, only the area covered by the white circle will be visible.
