AS3的一些图像处理说明

已知的一些图像处理，主要是得到颜色过滤矩阵，不完整，大家一起来补充。

//颜色转换数组，所有的0都是可调值
public var colorArray:Array = [1,0,0,0,0,0,1,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,1,0];

1.处理图像为灰度：
//取值范围0~3
colorArray[0] = (1-0)*0.3086+0;
colorArray[1] = (1-0)*0.6094;
colorArray[2] = (1-0)*0.0820;

colorArray[5] = (1-0)*0.3086;
colorArray[6] = (1-0)*0.6094+0;
colorArray[7] = (1-0)*0.0820;

colorArray[10] = (1-0)*0.3086;
colorArray[11] = (1-0)*0.6094;
colorArray[12] = (1-0)*0.0820+0;

colorArray[18] = 1;
image.filters = [new ColorMatrixFilter(colorArray)];

2.亮度调节：
var brightness:Number;//取值范围0~5
colorArray[0] = brightness;
colorArray[6] = brightness;
colorArray[12] = brightness;
colorArray[18] = 1;
img.filters = [new ColorMatrixFilter(colorArray)];

3.饱和度调节：
var saturation:Number;//取值范围0~3
colorArray[0] = (1-saturation)*0.3086+saturation;
colorArray[1] = (1-saturation)*0.6094;
colorArray[2] = (1-saturation)*0.0820;

colorArray[5] = (1-saturation)*0.3086;
colorArray[6] = (1-saturation)*0.6094+saturation;
colorArray[7] = (1-saturation)*0.0820;

colorArray[10] = (1-saturation)*0.3086;
colorArray[11] = (1-saturation)*0.6094;
colorArray[12] = (1-saturation)*0.0820+saturation;

colorArray[18] = 1;

img.filters = [new ColorMatrixFilter(colorArray)];

4.对比度调节：
var contrast:Number;//取值范围0~1
var a:Number = contrast*11;
var b:Number = 63.5-(contrast*698.5);
colorArray[0] = a;
colorArray[4] = b;
colorArray[6] = a;
colorArray[9] = b;
colorArray[12] = a;
colorArray[14] = b;
colorArray[18] = 1;
img.filters = [new ColorMatrixFilter(colorArray)];

5.水平翻转：
var planeBitmapData:BitmapData = new BitmapData( img.width, img.height );
var planeMatrix : Matrix = new Matrix(-1, 0, 0, 1, img.contentWidth, 0 );
planeBitmapData.draw( img, planeMatrix );
var planeBitmap:Bitmap = new Bitmap(planeBitmapData);
img.source = planeBitmap;

6.垂直翻转：
var apeakBitmapData:BitmapData = new BitmapData( img.width, img.height );
var apeakMatrix : Matrix = new Matrix(1, 0, 0, -1, 0, img.contentHeight );
var apeakBitmap:Bitmap = new Bitmap(apeakBitmapData);
apeakBitmapData.draw( img, apeakMatrix );
img.source = apeakBitmap;

7.浮雕效果：
img.filters = [new ConvolutionFilter(3,3,[-10,-1,0,-1,1,1,0,1,10])];
