OpenCV-Python is a library of Python bindings designed to solve computer vision problems.
cv2.circle() method is used to draw a circle on any image.
Syntax: cv2.circle(image, center_coordinates, radius, color, thickness)
image: It is the image on which circle is to be drawn.
center_coordinates: It is the center coordinates of circle. The coordinates are represented as tuples of two values i.e. (X coordinate value, Y coordinate value).
radius: It is the radius of circle.
color: It is the color of border line of circle to be drawn. For BGR, we pass a tuple. eg: (255, 0, 0) for blue color.
thickness: It is the thickness of the circle border line in px. Thickness of -1 px will fill the rectangle shape by the specified color.
Return Value: It returns an image.
Image used for all the below examples:
Using thickness of -1 px to fill the rectangle by red color.
