Inputs (4)
| Name | Type | Default | Description |
|---|---|---|---|
| src | COMFY_MATCHTYPE_V3 | Input 8-bit 3-channel image. 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. | |
| maskopt | NPARRAY,IMAGE,MASK | Input 8-bit 1 or 3-channel image. Optional - leave unconnected for the OpenCV default (None). 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. | |
| alphaopt | FLOAT | 0.2000-1e+38–1e+38 | Value ranges between 0-2. Preset to the OpenCV default (0.2). |
| betaopt | FLOAT | 0.4000-1e+38–1e+38 | Value ranges between 0-2. This is useful to highlight under-exposed foreground objects or to reduce specular reflections. Preset to the OpenCV default (0.4). |
Outputs (1)
| Name | Type | Description |
|---|---|---|
| result | COMFY_MATCHTYPE_V3 | Echoes the 'src' input's format: an IMAGE link comes back as IMAGE, MASK as MASK, NPARRAY stays NPARRAY. |
