Fills the area bounded by one or more polygons

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

Input

• img Image.
• pts Array of polygons 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 matrices.

Output

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

Options

• Color 3-element floating-point vector specifying polygon color. default zeros
• LineType Type of the polygon boundaries. 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
• Offset Optional offset of all points of the contours. default [0,0]

The function cv.fillPoly fills an area bounded by several polygonal contours. The function can fill complex areas, for example, areas with holes, contours with self-intersections (some of thier parts), and so forth.
