# OCIOCDLTransform

This node applies an ASC CDL grade. The calculation uses output = (i * s + o)^p where i is the input value, s is slope, o is offset and p is power.

Connection Type | Connection Name | Function
Input | input | The place in the node graph where the ASC CDL grade is applied.

Control (UI) | Default Value | Function
slope
r | 1 | Adjusts the slope value in the red channel.
g | 1 | Adjusts the slope value in the green channel.
b | 1 | Adjusts the slope value in the blue channel.
offset
r | 0 | Adjusts the offset value in the red channel.
g | 0 | Adjusts the offset value in the green channel.
b | 0 | Adjusts the offset value in the blue channel.
power
r | 1 | Adjusts the power value in the red channel.
g | 1 | Adjusts the power value in the green channel.
b | 1 | Adjusts the power value in the blue channel.
saturation | 1 | Scales the image saturation using the 709 ASC primaries.
direction | forward | The direction of the transform, with forward being used to bake in the color transform, and inverse typically reversing out a previously-baked in transform.
