Draws several polygonal curves

img = cv.polylines(img, pts)
[...] = cv.polylines(..., 'OptionName', optionValue, ...)

Input

• img Image.
• pts Array of polygonal curves, where each polygon is represented as an array of points. A cell array of cell arrays of 2-element vectors, in the form {{[x,y], [x,y], ...}, ...}, or a cell array of Nx2 matries.

Output

• img Output image, same size and type as input img.

Options

• Closed Flag indicating whether the drawn polylines are closed or not. If they are closed, the function draws a line from the last vertex of each curve to its first vertex. default true.
• Color 3-element floating-point vector specifying polyline color. default zeros
• Thickness Thickness of the polyline edges. default 1.
• LineType Type of the line segments. One of:
  • 4 4-connected line
  • 8 8-connected line (default)
  • AA anti-aliased line
• Shift Number of fractional bits in the vertex coordinates. default 0.

The function cv.polylines draws one or more polygonal curves.
