Invert

This node belongs to Krokodove Image Color Tools. Do not transfer the four InvertColor switches, a film-negative workflow or ColorMatrix Invert to it: these are separate operations with different controls.

Type offers Color, Luminance and Hue. Compare them on a frame containing colors and a gray scale, hold exposure fixed and change Type alone. A color negative, a luminance inversion and a hue change produce different results.

Luminance changes the image but does not turn it into a mask stream. For a technical map, first create the desired tonal pattern, then select Luminance in Bitmap and connect Bitmap.Mask to the next Merge mask input. An existing mask can often be reversed using its own Invert.

Pre-Divide / Post-Multiply supports color operations on premultiplied RGBA by dividing RGB by alpha before processing and multiplying afterward. It is not an alpha-inversion switch. Compare edges over light and dark backgrounds, inspect A separately, and avoid duplicate compensation.

The original Render capture shows 1x1, 2x2, 3x3, 4x4, 5x5, 8x8 and 16x16. Supersampling controls quality rather than inversion strength. Start at 1x1 and increase it only for a visible improvement in the actual graph; it cannot restore missing source detail.

The local-processing lesson routes clean and processed branches through Merge, where a mask and Blend control compositing. The brief BMD entry and Inspector captures do not establish additional Krokodove Flow sockets; this guide shows the minimal Input → Output path.

Judge the result in the actual processing space and signal range of the composition. Inverting HDR or scene-linear values is not film development. Exact Hue/Luminance formulas, extreme-value behavior and native rendering require verification in the installed build.
