演示程序会自动测试你是否有摄像头，如果有就调用摄像头，如果没有就调用一个swf动画文件

 

 

 

 

[AS3]DisplayEffect组件
【组件版本】：0.5
【功能简述】：可对DisplayObject显示类进行模糊，锐化，浮雕，色调，亮度，对比度等特效处理。
【运行平台】：Flash CS3，ActionScript3，Flash Player 9 +
【功能演示】：
演示程序会自动测试你是否有摄像头，如果有就调用摄像头，如果没有就调用一个swf动画文件。

【调用接口】：

public interface com.klstudio.images.DisplayEffect {

    //清除特效;
    function clear():void;

    //高斯模糊(uint);
    function blur(blurX:uint=4,blurY:uint=4):void;

    //浮雕([B,BL,BR,L,R,T,TL,TR],String);
    function emboss(direction:String = null):void;

    //锐化([1~3],uint)
    function sharpen(quality:uint=3):void;

    //色调([0x000000 ~ 0xFFFFFF],uint)
    function color(color:uint):void;

    //亮度([-255~255],int)
    function brightness(offset:int):void;

    //灰度
    function grayscale():void;

    //饱和度([0~3],Number)
    function saturation(strength:Number):void;

    //对比度([0~1],Number)
    function contrast(strength:Number):void;

    //反相
    function invert():void;
}

public interface com.klstudio.images.DisplayEffect { //清除特效; function clear():void; //高斯模糊(uint); function blur(blurX:uint=4,blurY:uint=4):void; //浮雕([B,BL,BR,L,R,T,TL,TR],String); function emboss(direction:String = null):void; //锐化([1~3],uint) function sharpen(quality:uint=3):void; //色调([0x000000 ~ 0xFFFFFF],uint) function color(color:uint):void; //亮度([-255~255],int) function brightness(offset:int):void; //灰度 function grayscale():void; //饱和度([0~3],Number) function saturation(strength:Number):void; //对比度([0~1],Number) function contrast(strength:Number):void; //反相 function invert():void; }
