据说图片都有颜色矩阵,像这样的。基本设置:- Dim mColorMatrix(0 To 4, 0 To 4) As Single
- mColorMatrix(0, 0) = -1: mColorMatrix(1, 0) = 0: mColorMatrix(2, 0) = 0: mColorMatrix(3, 0) = 0: mColorMatrix(4, 0) = 0
- mColorMatrix(0, 1) = 0: mColorMatrix(1, 1) = -1: mColorMatrix(2, 1) = 0: mColorMatrix(3, 1) = 0: mColorMatrix(4, 1) = 0
- mColorMatrix(0, 2) = 0: mColorMatrix(1, 2) = 0: mColorMatrix(2, 2) = -1: mColorMatrix(3, 2) = 1: mColorMatrix(4, 2) = 0
- mColorMatrix(0, 3) = 0: mColorMatrix(1, 3) = 0: mColorMatrix(2, 3) = 0: mColorMatrix(3, 3) = 0: mColorMatrix(4, 3) = 0
- mColorMatrix(0, 4) = 0: mColorMatrix(1, 4) = 0: mColorMatrix(2, 4) = 0: mColorMatrix(3, 4) = 0: mColorMatrix(4, 4) = 1
复制代码 然后,再设置mColorMatrix(0, 0)、mColorMatrix(1, 1)、mColorMatrix(2, 2)、mColorMatrix(3, 3)、mColorMatrix(4, 4),对应颜色的绿、蓝、红。不知道这是否是色相?
