ImGui.ImDrawList_AddPolyline

ImDrawList_AddPolyline(
    self: ImDrawList,
    points: Float32Array,
    num_points: number,
    col: number,
    flags: number,
    thickness: number,
): void
Add a polyline to the draw list.

Parameters
self
ImDrawList
ImDrawList handle on which this method operates.

points
Float32Array
Float32Array of consecutive [x,y] points in screen coordinates; provide at least 2 * num_points elements. Filled polygons require clockwise order. Pass Float32Array storage, not a JS scalar; native access uses the supplied backing memory.

num_points
number
Number of coordinate pairs to read from points.

col
number
Packed ImU32 RGBA color; alpha controls opacity.

flags
number
ImDrawFlags options controlling this operation; combine compatible flag bits with |.

thickness
number
Stroke thickness in screen pixels.

Returns
void
Remarks
- Only simple polygons are supported by filling functions (no self-intersections, no holes).
- Concave polygon fill is more expensive than convex one: it has O(N^2) complexity. Provided as a convenience for the user but not used by the main library.
