CV Draw Polygon

Draws a polygon/polyline through the given points (cv2.polylines or cv2.fillPoly) - e.g. a projected object outline or rotated text detection quads. When several outlines share one image, vary 'line_style' as well as the color so they stay tellable apart without relying on hue. Accepts IMAGE or MASK input. When thickness is 0, polygons are filled (useful for creating masks from rotated quads). Multiple polygons: pass an (N, M, 2) array to draw N separate M-point polygons (e.g. the quads output from 'CV EAST Text Detect'). To draw conditionally (e.g. only when 'CV Find Homography' reports found=true), select between this node's output and the original image with a control-flow node such as Basic data handling's 'if/else' - its lazy inputs skip the drawing branch entirely when it is not taken.
