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)

NameTypeDefaultDescription
sourceCOMFY_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.
centerCV_TUPLE0,0Center 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.
axesCV_TUPLE0,0Half 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.
angleFLOAT0.0000-1e+38–1e+38Ellipse rotation angle in degrees.
startAngleFLOAT0.0000-1e+38–1e+38Starting angle of the elliptic arc in degrees.
endAngleFLOAT0.0000-1e+38–1e+38Ending angle of the elliptic arc in degrees.
colorSTRING(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.
thicknessoptINT1-2147483648–2147483647Thickness 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).
lineTypeoptCOMBOLINE_AAType of the ellipse boundary. See #LineTypes
shiftoptINT0-2147483648–2147483647Number of fractional bits in the coordinates of the center and values of axes. Preset to the OpenCV default (0).

NameTypeDescription
resultCOMFY_MATCHTYPE_V3Echoes the 'source' input's format: an IMAGE link comes back as IMAGE, MASK as MASK, NPARRAY stays NPARRAY.
