ComfyUI Node
cv2.drawMarker
Raw wrapper of cv2.drawMarker(source, position, color, markerType?, markerSize?, thickness?, line_type?). Parameters marked '?' are optional; blank means OpenCV default. See the OpenCV documentation for details.

Inputs (7)
| 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. | |
| position | CV_TUPLE | 0,0 | The point where the crosshair is positioned. 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. |
| color | STRING | (0, 0, 0, 0) | Line 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. |
| markerTypeopt | COMBO | MARKER_CROSS | The specific type of marker you want to use, see #MarkerTypes |
| markerSizeopt | INT | 20-2147483648–2147483647 | The length of the marker axis [default = 20 pixels] Preset to the OpenCV default (20). |
| thicknessopt | INT | 1-2147483648–2147483647 | Line thickness. Preset to the OpenCV default (1). |
| line_typeopt | COMBO | LINE_AA | Type of the line, See #LineTypes |
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. |
