　　先看效果：

点击这里下载源文件

　　制作非常简单，新建立文档，然后按Ctrl J修改属性。

　　按Ctrl R导入一幅图片，或者自己绘制一幅铅笔图。

　　按F8转变为元件。

　　为该元件设置实例名。

　　选择第一帧，添加如下Action。

this.attachMovie(\"cursor_id\", \"cursor_mc\", this.getNextHighestDepth(),
{_x:_xmouse, _y:_ymouse});
Mouse.hide();
var mouseListener:Object = new Object();
mouseListener.onMouseMove = function() {
pencil._x = _xmouse;
pencil._y = _ymouse;
updateAfterEvent();
};//建立一个铅笔图标

Mouse.addListener(mouseListener);//和铅笔图片联系在一起

this.createEmptyMovieClip(\"drawing_mc\", this.getNextHighestDepth());
var mouseListener:Object = new Object();
mouseListener.onMouseDown = function() {
this.drawing = true;
drawing_mc.moveTo(_xmouse, _ymouse);
drawing_mc.lineStyle(3, 0x99CC00, 100);
};

mouseListener.onMouseUp = function() {
this.drawing = false;
};

mouseListener.onMouseMove = function() {
if (this.drawing) {
drawing_mc.lineTo(_xmouse, _ymouse);
}
updateAfterEvent();
};

Mouse.addListener(mouseListener);

var keyListener:Object = new Object();
keyListener.onKeyDown = function() {
if (Key.isDown(Key.DELETEKEY) || Key.isDown(Key.BACKSPACE)) {
drawing_mc.clear();
}
};

Key.addListener(keyListener);
