clone (BitmapData.clone method)
public clone() : BitmapData
Returns a new BitmapData object that is a clone of the original instance with an exact copy of
the contained bitmap.
Availability: ActionScript 1.0; Flash Player 8
Returns
flash.display.BitmapData - A new BitmapData object that is identical to the original.
Example
The following example creates three BitmapData objects and compares them. You can create
the
bitmap_1 instance by using the BitmapData constructor. You create the bitmap_2
instance by setting it equal to
bitmap_1. You create he clonedBitmap instance by cloning
bitmap_1. Notice that although bitmap_2 evaluates as being equal to bitmap_1,
clonedBitmap does not, even though it contains the same values as bitmap_1.
import flash.display.BitmapData;
var bitmap_1:BitmapData = new BitmapData(100, 80, false, 0x000000);
var bitmap_2:BitmapData = bitmap_1;
var clonedBitmap:BitmapData = bitmap_1.clone();
trace(bitmap_1 == bitmap_2); // true
trace(bitmap_1 == clonedBitmap); // false
for(var i in bitmap_1) {
trace(">> " + i + ": " + bitmap_1[i]);
