BitmapData (flash.display.BitmapData) 331

transparent (BitmapData.transparent property)

public transparent : Boolean [read-only]

Defines whether the bitmap image supports per-pixel transparency. You can set this value only

when you construct a BitmapData object by passing in

true for the transparent parameter.

After you create a BitmapData object, you can check whether it supports per-pixel

transparency by seeing if the value of the

transparent property is true.

Availability: ActionScript 1.0; Flash Player 8

Example

The following example shows that the

transparent property of the Bitmap instance is read-

only by trying to set it and failing:

import flash.display.BitmapData;

var myBitmapData:BitmapData = new BitmapData(100, 80, false, 0x00CCCCCC);

var mc:MovieClip = this.createEmptyMovieClip("mc",

this.getNextHighestDepth());

mc.attachBitmap(myBitmapData, this.getNextHighestDepth());

trace(myBitmapData.transparent); // false

myBitmapData.transparent = true;

trace(myBitmapData.transparent); // false

width (BitmapData.width property)

public width : Number [read-only]

The width of the bitmap image in pixels.
