What’s new in Flash Asset Xtra 9

Load new kinds of image files at runtime, such as progressive JPEG images and non-

animated GIF and PNG files. If you load an animated file, the first frame of that animation

appears in the SWF file.

Bitmap caching lets you improve the performance of your applications at runtime by caching

a bitmap representation of your vector button or movie clip instances at runtime. You can use

ActionScript code to access this property or select the instance and then select an option in the

Property inspector to cache the instance. Caching a movie clip as a bitmap prevents Flash

Player from having to redraw the image continually, providing a significant improvement in

playback performance.

Alpha channel masking is supported if both the mask and the maskee movie clips use bitmap

caching. This support also lets you use a filter on the mask independently of the filter that is

applied to the maskee itself.

9-slice scaling enables you to scale movie clip instances without widening the strokes that

outline the movie clip. You can use ActionScript code or the Flash user interface to access this

feature.

The Flash Asset Xtra 8 supports 9-slice scaling of movie clips within Flash 8 sprites. 9-slice

scaling lets you scale movie clip instances without widening the strokes that outline the movie

clip. You can use ActionScript code or the Flash user interface to access this feature in either

Flash Basic 8 or Flash Professional 8.

A new garbage collector is built into Flash Player. It uses an incremental collector to

improve performance. For more information, see the Macromedia Flash Developer Center

article Performance Improvements in Flash Player 8.

NOTE

Mask layers do not support alpha channel masking. You must use ActionScript code to

apply a mask and use runtime bitmap caching.
