		<description><![CDATA[接下来的例子演示了Flex中如何将颜色的值转化为字符串，根据RGB计算出各个值以及格式化颜色值。
让我们先来看一下Demo（可以右键View Source或点击这里察看源代码）：

		<description><![CDATA[ActionScript 3可以显示一幅通过代码计算得出RGB值而动态生成的bigmap图像。利用这种特性，演绎3D元素，制作影像和图片以及其他的效果都显得比较容易。为了在显示器屏幕中描画像素，就需要创建一个Bitmap和BitmapData类的实例，BitmapData表示一组像素，而Bitmap则是用来描画这些像素的一个DisplayObject对象。为了动态的描画出逼真的bitmap图像，就需要在各个框架中写入所有的像素。而实现这一点，至少有两种方法：一种是通过给每一个像素调用一次setPixel，还有一种是创建一个适当大小的ByteArray，然后将其传给BitmapData.setPixels.所以，如果你希望你的代码执行的足够快，那应该选择哪一种呢？
下面的代码应该是最快的了：








outputBitmapData.lock();
for(y = 0; y &#60; STAGE_HEIGHT; ++y)
{
&#160; for(x = 0; x &#60; STAGE_WIDTH; ++x)
&#160; {
&#160; &#160; r = (t*100 + 255 * x&#160;/ STAGE_WIDTH)%255;
&#160; &#160; g = 180;
&#160; &#160; b = 180;
&#160;
&#160; &#160; outputBitmapData.setPixel(x, y, (r&#60;&#60;16) + (g&#60;&#60;8) + b);
&#160; }
}
outputBitmapData.unlock();
