如何使用工具ColorMatrix反转图像的颜色？

Question

我必须在矩阵中放入什么值？

Dim clMatriz As Imaging.ColorMatrix = New Imaging.ColorMatrix(New Single()() _
{New Single() {¿?, 0, 0, 0, 0}, _
 New Single() {0, ¿?, 0, 0, 0}, _
 New Single() {0, 0, ¿?, 0, 0}, _
 New Single() {0, 0, 0, ¿?, 0}, _
 New Single() {0, 0, 0, 0, ¿?})

虽然我不是很确定你的颜色矩阵的特定版本是如何工作的，如果你的像素值在0-255或0-1的范围内，这里是它应该如何工作的：

如果您的像素范围是0-255：

Dim clMatriz As Imaging.ColorMatrix = New Imaging.ColorMatrix(New Single()() _ {New Single() {-1, 0, 0, 0, 255}, _ New Single() {0, -1, 0, 0, 255}, _ New Single() {0, 0, -1, 0, 255}, _ New Single() {0, 0, 0, 1, 0}, _ New Single() {0, 0, 0, 0, 1})

如果是0-1：

Dim clMatriz As Imaging.ColorMatrix = New Imaging.ColorMatrix(New Single()() _ {New Single() {-1, 0, 0, 0, 1}, _ New Single() {0, -1, 0, 0, 1}, _ New Single() {0, 0, -1, 0, 1}, _ New Single() {0, 0, 0, 1, 0}, _ New Single() {0, 0, 0, 0, 1})
