我是Flash的初学者。我想加载图像，在图像上显示光标，在鼠标按下时我想模糊图像的实际部分。（例如，您可以在图像上模糊您的脸，然后保存新图像）。

我可以用白线删除部分图像，但我想模糊它

    // LIVE JPEG ENCODER 0.3
// from bytearray.org
import asfiles.encoding.JPEGEncoder;
import flash.external.ExternalInterface;

ExternalInterface.addCallback("flash_saveImage", inflash_saveImage);

var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, handleComplete);
loader.load(new URLRequest(loaderInfo.parameters._filename));
//loader.load(new URLRequest("b.jpg"));

var container_mc:MovieClip = new MovieClip;//create movieclip

function handleComplete(e:Event):void 
    {
    addChild(container_mc);
    var bitmapData:BitmapData = Bitmap(e.target.content).bitmapData;
    var matrix:Matrix = new Matrix();
    container_mc.graphics.clear();
    container_mc.graphics.beginBitmapFill(bitmapData, matrix, false);
    //container_mc.graphics.beginFill(0xFFFFFF,0);
    container_mc.graphics.drawRect(0, 0, bitmapData.width, bitmapData.height);
    container_mc.graphics.endFill();
    swapChildren(container_mc, pencil);
    container_mc.addEventListener(MouseEvent.MOUSE_DOWN, startDrawing);
    container_mc.addEventListener(MouseEvent.MOUSE_UP, stopDrawing);
    container_mc.addEventListener(MouseEvent.MOUSE_MOVE, makeLine);     
    }

    stage.addEventListener(MouseEvent.MOUSE_MOVE, moveCursor);
    Mouse.hide();

function moveCursor(event:MouseEvent):void
{
    pencil.x = event.stageX;
    pencil.y = event.stageY;
}

function startDrawing(event:MouseEvent):void{   
    container_mc.graphics.lineStyle(20, 0xFFFFFF, 1);
    container_mc.graphics.moveTo(mouseX, mouseY);
    container_mc.addEventListener(MouseEvent.MOUSE_MOVE, makeLine);
}

function stopDrawing(event:MouseEvent):void{
    container_mc.removeEventListener(MouseEvent.MOUSE_MOVE, makeLine);
}

function makeLine(event:MouseEvent):void{
    container_mc.graphics.lineTo(mouseX, mouseY);
}


function inflash_saveImage ( ):void 
    {
    var myURLLoader:URLLoader = new URLLoader();
    var myBitmapSource:BitmapData = new BitmapData ( container_mc.width, container_mc.height );

    // render the player as a bitmapdata
    myBitmapSource.draw ( container_mc );

    // create the encoder with the appropriate quality
    var myEncoder:JPEGEncoder = new JPEGEncoder( 80 );

    // generate a JPG binary stream to have a preview
    var myCapStream:ByteArray = myEncoder.encode ( myBitmapSource );

    var header:URLRequestHeader = new URLRequestHeader ("Content-type", "application/octet-stream");

    var myRequest:URLRequest = new URLRequest ( "save.php" );

    myRequest.requestHeaders.push (header);

    myRequest.method = URLRequestMethod.POST;

    myRequest.data = myCapStream;
    myURLLoader.load ( myRequest );

}

谢谢，小村庄

我可以为您的问题想出一种解决方案。制作原始图像的副本并将其全部模糊。然后使用鼠标定位从模糊图像中复制像素的蒙版，并将其添加到原始图像的顶部。最后你只需要保存原始图像加上模糊的部分

-> 透明容器（这是您将绘制像素的地方）

-> 原始图像

-> 模糊图像（无需添加到显示列表，用作绘制模糊像素的源）

我没有尝试过模糊处理，但做了类似的事情来将过滤器应用于图像的一部分，据我所知，这是设置。
