SWF It Good

How to use Bitmap and BitmapData in ActionScript 3 – v3

April 29th, 2008

Alright, this example is very similar to the other examples I have done. But with this one I am scaling all pixels at the same rate. Just click on it the image in the example Source | Example

[as] import flash.display.*;
import caurina.transitions.Tweener;
import flash.sampler.*;

var pixHolder:Sprite = new Sprite();

var img:Img = new Img();
//pixHolder.opaqueBackground = true;

addChild(pixHolder);

var coords_array:Array = [];
var pixels_array:Array = [];

var bmd:BitmapData = new BitmapData(img.width, img.height, false);
bmd.draw(img, new Matrix());
bmd.lock();
startSampling();

for (var i:int = 0; i < img.width; i++)
{
for (var j:int = 0; j < img.height; j++)
{
var coords:Object = {};

//var pixData:BitmapData = new BitmapData(1, 1, false, bmd.getPixel(i, j));

//var pixBit:Bitmap = new Bitmap(pixData, PixelSnapping.ALWAYS, true);

var pixSprite:Sprite = new Sprite();
pixSprite.graphics.beginFill(bmd.getPixel(i, j), 1);
pixSprite.graphics.drawRect(0, 0, 1, 1);
pixSprite.graphics.endFill();

pixSprite.x = i;
pixSprite.y = j;
//pixSprite.filters = [new BlurFilter(5, 5, 3)];
//pixSprite.addChild(pixBit);
pixHolder.addChild(pixSprite);

coords.sprite = pixSprite;
coords.x = i;
coords.y = j;
coords_array.push(coords);
}
}
trace(”what: ” +getSampleCount() )

bmd.unlock();
bmd.dispose();
stage.addEventListener(MouseEvent.CLICK, updating, false, 0, true);

function updating(evt:MouseEvent):void
{
removeEventListener(MouseEvent.CLICK, updating);
trace(”over”);

for(var k:int = 0; k < coords_array.length; k++)
{
Tweener.addTween(coords_array[k].sprite, {x:coords_array[k].sprite.x * 2, scaleX:coords_array[k].sprite.scaleX * 2, scaleY:coords_array[k].sprite.scaleY * 2, delay:.5,  y:coords_array[k].sprite.y * 2, transition:”linear”, time:.5});
}
trace(getSampleCount() )
}
[/as]
