I want to get the color from the movieclip. I am Using Following Code:

for (var j = 0; j <bmpd.width; j++)
{
    for (var k = 0; k <bmpd.height; k++)
    {
        trace("0x"+bmpd.getPixel(j,k).toString(16))
    }
}

推荐答案

为了让您的影片剪辑颜色在某一个点或范围，应创建所需的容量（1×1的点）的透明的BitmapData，和0x0填充颜色，然后创建的BitmapData的变换矩阵对齐（0,0）到您所在区域的左上角，然后绘制了MC的位图，然后就可以查询它的像素。一个例子（一个点）：

To get a color on your MovieClip at a certain point or range, you should create a transparent BitmapData of required capacity (1x1 for point), fill it with 0x0 color, then create a transform matrix aligning (0,0) of BitmapData to upper left corner of your region, then draw that MC on the bitmap, then you can query its pixels. An example (a point):

private static var hitTestBD:BitmapData=new BitmapData(1,1,true,0);
private static vat hitTestMatrix:Matrix=new Matrix(); 
public static function getMCColor(mc:DisplayObject,tx:Number,ty:Number):uint {
    hitTestMatrix.identity();
    hitTestMatrix.translate(-1*tx,-1*ty); // aligning
    hitTestBD.fillRect(hitTestBD.rect,0x0);
    hitTestBD.draw(mc,hitTestMatrix);
    return hitTestBD.getPixel32(0,0);
}
