Inputs (3)
| Name | Type | Default | Description |
|---|---|---|---|
| dst | COMFY_MATCHTYPE_V3 | output array of random numbers; the array must be pre-allocated. The image output(s) echo this input's format. The low-level cv2 function writes its result into this array in place, but this wrapper passes cv2 a private copy, so your input array is never modified. 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. | |
| low | NPARRAY | inclusive lower boundary of the generated random numbers. A data array (points / matrix), NOT an image - only an NPARRAY link is accepted here. | |
| high | NPARRAY | exclusive upper boundary of the generated random numbers. A data array (points / matrix), NOT an image - only an NPARRAY link is accepted here. |
Outputs (1)
| Name | Type | Description |
|---|---|---|
| result | COMFY_MATCHTYPE_V3 | Echoes the 'dst' input's format: an IMAGE link comes back as IMAGE, MASK as MASK, NPARRAY stays NPARRAY. |
