Summary
Twists the colors of the image.
Description
Color twist conversion component uses values of all color channels of a source pixel to compute the resultant destination channel value. The destination channel value is obtained as the result of multiplying the corresponding row of the color-twist matrix by the vector of source pixel channel values.
For example,if (r,g,b) is a source pixel, then the destination pixel values (R,G,B)are computed as follows:
R := RedTwist.Red * r + RedTwist.Green * g + RedTwist.Blue * b + RedTwist.Offset; G := GreenTwist.Red * r + GreenTwist.Green * g + GreenTwist.Blue * b + GreenTwist.Offset; B := BlueTwist.Red * r + BlueTwist.Green * g + BlueTwist.Blue * b + BlueTwist.Offset;
