ComfyUI Node
cv2.ellipse (1/2)
Raw wrapper of cv2.ellipse(source, center, axes, angle, startAngle, endAngle, color, thickness?, lineType?, shift?). Parameters marked '?' are optional; blank means OpenCV default. See the OpenCV documentation for details.

Inputs (10)
| 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. | |
| center | CV_TUPLE | 0,0 | Center of the ellipse. One value with 2 components (x, y) - it travels as a whole, so it cannot arrive half-connected. Wire it from 'CV Tuple' or type the components in place. |
| axes | CV_TUPLE | 0,0 | Half of the size of the ellipse main axes. One value with 2 components (w, h) - it travels as a whole, so it cannot arrive half-connected. Wire it from 'CV Tuple' or type the components in place. |
| angle | FLOAT | 0.0000-1e+38–1e+38 | Ellipse rotation angle in degrees. |
| startAngle | FLOAT | 0.0000-1e+38–1e+38 | Starting angle of the elliptic arc in degrees. |
| endAngle | FLOAT | 0.0000-1e+38–1e+38 | Ending angle of the elliptic arc in degrees. |
| color | STRING | (0, 0, 0, 0) | Ellipse color. 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 the ellipse arc outline, if positive. Otherwise, this indicates that a filled ellipse sector is to be drawn. Preset to the OpenCV default (1). |
| lineTypeopt | COMBO | LINE_AA | Type of the ellipse boundary. See #LineTypes |
| shiftopt | INT | 0-2147483648–2147483647 | Number of fractional bits in the coordinates of the center and values of axes. 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. |
