RETURN TYPEvoid

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

example: samples/cpp/tutorial_code/ImgProc/basic_drawing/Drawing_1.cpp An example using drawing functions Check tutorial_random_generator_and_text "the corresponding tutorial" for more details Fills the area bounded by one or more polygons.

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 their parts), and so forth.
