OpenCV-Python is a library of Python bindings designed to solve computer vision problems.
cv2.rectangle() method is used to draw a rectangle on any image.
Syntax: cv2.rectangle(image, start_point, end_point, color, thickness)
image: It is the image on which rectangle is to be drawn.
start_point: It is the starting coordinates of rectangle. The coordinates are represented as tuples of two values i.e. (X coordinate value, Y coordinate value).
end_point: It is the ending coordinates of rectangle. The coordinates are represented as tuples of two values i.e. (X coordinate value, Y coordinate value).
color: It is the color of border line of rectangle to be drawn. For BGR, we pass a tuple. eg: (255, 0, 0) for blue color.
thickness: It is the thickness of the rectangle 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 black color.
