Bitmap and BitmapData

Learn Bitmap and BitmapData in ActionScript 3 with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.

12 min read • Intermediate

Bitmap and BitmapData is an atomic ActionScript 3 topic inside Display List. The example below uses the actual construct named by the lesson rather than a generic placeholder.

Focus on what Bitmap and BitmapData changes: the input, binding, control path, object state, collection, runtime effect, or language contract. Then alter one value and verify that the behavior changes for a reason specific to this feature.

Topic-specific example

actionscript-06-07-bitmap-and-bitmapdata.as
actionscript Try It Live 
import flash.display.BitmapData; import flash.display.Bitmap; var data:BitmapData=new BitmapData(32,32,false,0xFFCC00); addChild(new Bitmap(data));
Edge case / engineering note

Check the input collection shape, whether the operation mutates or returns a new value, and what happens for an empty collection.
