Circle(InputOutputArray, int, int, int, Scalar, int, LineTypes, int)

Draws a circle

public static void Circle(InputOutputArray img, int centerX, int centerY, int radius, Scalar color, int thickness = 1, LineTypes lineType = LineTypes.Link8, int shift = 0)

Parameters

img InputOutputArray

Image where the circle is drawn.

centerX int

X-coordinate of the center of the circle.

centerY int

Y-coordinate of the center of the circle.

radius int

Radius of the circle.

color Scalar

Circle color.

thickness int

Thickness of the circle outline if positive, otherwise indicates that a filled circle has to be drawn. [By default this is 1]

lineType LineTypes

Type of the circle boundary. [By default this is LineType.Link8]

shift int

Number of fractional bits in the center coordinates and radius value. [By default this is 0]
