Inputs (4)
| Name | Type | Default | Description |
|---|---|---|---|
| src | COMFY_MATCHTYPE_V3 | Input three-channel image in the BGR color space (either CV_8UC3 or CV_16UC3) The image output(s) echo this input's format. Accepts a ComfyUI IMAGE/MASK directly (frame 0 of a batch) or an NPARRAY. Arithmetic ops (add, multiply, etc.) process the full IMAGE batch when both inputs have the same batch size. | |
| gainB | FLOAT | 0.0000-1e+38–1e+38 | gain for the B channel |
| gainG | FLOAT | 0.0000-1e+38–1e+38 | gain for the G channel |
| gainR | FLOAT | 0.0000-1e+38–1e+38 | gain for the R channel |
