VectorToColor node — Natron 2.5.0 documentation

# VectorToColor node

This documentation is for version 1.0 of VectorToColor (net.sf.openfx.VectorToColorPlugin).

## Description

Convert x and y vector components to a color representation.

H (hue) gives the direction, S (saturation) is set to the amplitude/norm, and V is 1.The role of S and V can be switched.Output can be RGB or HSV, with H in degrees.

## Inputs

Input | Description | Optional
--- | --- | ---
Source |  | No

## Controls

Parameter / script name | Type | Default | Function
--- | --- | --- | ---
X channel / `xChannel` | Choice | r | Selects the X component of vectors r: R channel from input. g: G channel from input. b: B channel from input. a: A channel from input.
Y channel / `yChannel` | Choice | g | Selects the Y component of vectors r: R channel from input. g: G channel from input. b: B channel from input. a: A channel from input.
Opposite / `opposite` | Boolean | Off | If checked, opposite of X and Y are used.
Inverse Y / `inverseY` | Boolean | On | If checked, opposite of Y is used (on by default, because most optical flow results are shown using a downward Y axis).
Modulate V / `modulateV` | Boolean | Off | If checked, modulate V using the vector amplitude, instead of S.
HSV Output / `hsvOutput` | Boolean | Off | If checked, output is in the HSV color model.
