Invert
Invert
Use Invert to flip channel polarity when a workflow expects opposite mask semantics. It is a quick fix for switching between cutout and keep regions.
Availability
This node is available in the free feature set.
Common uses
- Place channel nodes after generators and before final output shaping.
- Use histogram and levels tools to isolate useful ranges for masks.
Input ports
-
input -
Usually expects one image input, with optional secondary inputs for some nodes.
Output ports
-
out -
Outputs modified image or channel data for downstream processing.
Parameters
This node has no shared processing parameters.
Behavior
- These nodes remap values rather than creating major new structure.
- Channel operations are useful for converting outputs into mask-friendly ranges.
Common mistakes
- Stacking many remap nodes can flatten contrast unexpectedly.
- Watch channel assumptions when mixing grayscale and RGBA signals.
