as3.0 Flex 图像处理

? //颜色转换数组，所有的0都是可调值 public var colorArray:Array = [1,1,0]; 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,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,-1,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,[-10,10])];
