Inputs (3)
| Name | Type | Default | Description |
|---|---|---|---|
| src1 | NPARRAY,IMAGE,MASK | first input array. 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. | |
| src2 | NPARRAY,IMAGE,MASK | second input array of the same size as src1. 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. | |
| Ropt | FLOAT | 255.0000-1e+38–1e+38 | the maximum pixel value (255 by default) Preset to the OpenCV default (255.0). |
