Flash图片处理—颜色变换

运算公式：

redResult = a[0] * srcR + a[1] * srcG + a[2] * srcB + a[3] * srcA + a[4]
greenResult = a[5] * srcR + a[6] * srcG + a[7] * srcB + a[8] * srcA + a[9]
blueResult = a[10] * srcR + a[11] * srcG + a[12] * srcB + a[13] * srcA + a[14]
alphaResult = a[15] * srcR + a[16] * srcG + a[17] * srcB + a[18] * srcA + a[19]

var filterObj = new flash.filters.ColorMatrixFilter();    
filterObj.matrix = new Array(    
    0,0,1,0,0,    
    0,1,0,0,0,    
    1,0,0,0,0,    
    0,0,0,1,0);    
displayObject.filters = [filterObj]; 

黑白：

var filterObj = new flash.filters.ColorMatrixFilter();    
filterObj.matrix = new Array(    
    1/3,1/3,1/3,0,0,    
    1/3,1/3,1/3,0,0,    
    1/3,1/3,1/3,0,0,    
      0,  0,  0,1,0);    
displayObject.filters = [filterObj];  

旧照片：

var filterObj = new flash.filters.ColorMatrixFilter();    
filterObj.matrix = new Array(    
    1/2,1/2,1/2,0,0,    
    1/3,1/3,1/3,0,0,    
    1/4,1/4,1/4,0,0,    
      0,  0,  0,1,0);    
displayObject.filters = [filterObj];
