### ImageProcessing.Compute.Color.Transform

This node applies a 4x4 color transformation matrix to the RGBA color values of an image. The 4x4 matrix $\mathtt{T}$ can be set via the transform input slot. Then the color of each output pixel is computed by:
$\begin{pmatrix}R_{\mathrm{out}}\\G_{\mathrm{out}}\\B_{\mathrm{out}}\\A_{\mathrm{out}}\end{pmatrix} = \mathtt{T}\, \begin{pmatrix}R_{\mathrm{in}}\\G_{\mathrm{in}}\\B_{\mathrm{in}}\\A_{\mathrm{in}}\end{pmatrix}$
