To further demonstrate the relationships between bitmap_1, bitmap_2, and clonedBitmap
the following example modifies the pixel value at (1, 1) of bitmap_1. Modifying pixel value at
(1, 1) demonstrates that the clone() method creates an instance based on values of the
bitmap_1 instance instead of referring to the values.
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.getPixel32(1, 1)); // -16777216
trace(bitmap_2.getPixel32(1, 1)); // -16777216
trace(clonedBitmap.getPixel32(1, 1)); // -16777216
bitmap_1.setPixel32(1, 1, 0xFFFFFF);
trace(bitmap_1.getPixel32(1, 1)); // -1
trace(bitmap_2.getPixel32(1, 1)); // -1
trace(clonedBitmap.getPixel32(1, 1)); // -16777216
colorTransform (BitmapData.colorTransform
method)
public colorTransform(rect:Rectangle, colorTransform:ColorTransform) : Void
Adjusts the color values in a specified area of a bitmap image by using a ColorTransform
object. If the rectangle matches the boundaries of the bitmap image, this method transforms
the color values of the entire image.
Availability: ActionScript 1.0; Flash Player 8
Parameters
rect:Rectangle - A Rectangle object that defines the area of the image in which the
ColorTransform object is applied.
colorTransform:ColorTransform - A ColorTransform object that describes the color
transformation values to apply.
Example
The following example shows how to apply a color transform operation to a BitmapData
instance.
import flash.display.BitmapData;
BitmapData (flash.display.BitmapData) 309
