ComfyUI Node
cv2.rectangle (2/2)
Raw wrapper of cv2.rectangle(source, rec, color, thickness?, lineType?, shift?). Parameters marked '?' are optional; blank means OpenCV default. See the OpenCV documentation for details.

Inputs (9)
| Name | Type | Default | Description |
|---|---|---|---|
| source | COMFY_MATCHTYPE_V3 | 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. | |
| rec_x | INT | 0-2147483648–2147483647 | Rectangle top-left corner X in pixels. |
| rec_y | INT | 0-2147483648–2147483647 | Rectangle top-left corner Y in pixels. |
| rec_w | INT | 00–2147483647 | Rectangle width in pixels (>= 0). |
| rec_h | INT | 00–2147483647 | Rectangle height in pixels (>= 0). |
| color | STRING | (0, 0, 0, 0) | Rectangle color or brightness (grayscale image). cv2 Scalar as a literal, e.g. "(0, 255, 0)" (BGR) or "(0, 255, 0, 64)" (BGRA). A bare number broadcasts to every component, so "255" means (255, 255, 255, 255). Components past the target's channel count are ignored by OpenCV. |
| thicknessopt | INT | 1-2147483648–2147483647 | Thickness of lines that make up the rectangle. Negative values, like #FILLED, mean that the function has to draw a filled rectangle. Preset to the OpenCV default (1). |
| lineTypeopt | COMBO | LINE_AA | Type of the line. See #LineTypes |
| shiftopt | INT | 0-2147483648–2147483647 | Number of fractional bits in the point coordinates. Preset to the OpenCV default (0). |
Outputs (1)
| Name | Type | Description |
|---|---|---|
| result | COMFY_MATCHTYPE_V3 | Echoes the 'source' input's format: an IMAGE link comes back as IMAGE, MASK as MASK, NPARRAY stays NPARRAY. |
