mapBitmap (DisplacementMapFilter.mapBitmap
property)
public mapBitmap : BitmapData
A BitmapData object containing the displacement map data.

mapBitmap property cannot be changed by directly modifying its value. Instead, you
must get a reference to
mapBitmap, make the change to the reference, and then set mapBitmap
to the reference.

Example
The following example changes the
mapBitmap property on the existing MovieClip
filteredMc when a user clicks it.
import flash.filters.DisplacementMapFilter;
import flash.display.BitmapData;
import flash.geom.Point;
import flash.geom.Matrix;
import flash.geom.ColorTransform;
var filteredMc:MovieClip = createDisplacementMapRectangle();
var scope:Object = this;
filteredMc.onPress = function() {
var filter:DisplacementMapFilter = this.filters[0];
filter.mapBitmap = scope.createGradientBitmap(300, 80, 0xFF000000,
"linear");
this.filters = new Array(filter);
}
function createDisplacementMapRectangle():MovieClip {
var mapBitmap:BitmapData = createGradientBitmap(300, 80, 0xFF000000,
"radial");
var filter:DisplacementMapFilter = new DisplacementMapFilter(mapBitmap,
new Point(-30, -30), 1, 1, 10, 10, "wrap", 0x000000, 0x000000);
var txtBlock:MovieClip = createTextBlock();
