Overview

Combines R, G, B and A channel images into RGBA.

Reads each channel image's red plane and reconstructs RGBA without quantization. Missing RGB channels default to 0; missing alpha defaults to 1.

Usage

In practice

  • Use Combine Color when the graph needs Combines R, G, B and A channel images into RGBA.
  • Reads each channel image's red plane and reconstructs RGBA without quantization. Missing RGB channels default to 0; missing alpha defaults to 1.
  • Use it after a source or scalar field, then send the adjusted image or colour value to a downstream composite or material stage.
  • Separate Color Splits an RGBA image into R, G, B and A grayscale images.
  • Colorize Maps an Image scalar field through a four-stop colour ramp; use Color Ramp only for a Scalar value.
  • Hue / Saturation / Value Recolors an image in HSV space while preserving alpha.
