Python OpenCV | cv2.line() method
OpenCV-Python is a library of Python bindings designed to solve computer vision problems.cv2.line() method is used to draw a line on any image.
cv2.line(image, start_point, end_point, color, thickness)
Parameters: image: It is the image on which line is to be drawn.
- start_point: It is the starting coordinates of the line. 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 the line. The coordinates are represented as tuples of two values i.e. (X coordinate value, Y coordinate value).
- color: It is the color of the line to be drawn. For RGB, we pass a tuple. eg: (255, 0, 0) for blue color.
- thickness: It is the thickness of the line in px.
Return Value: It returns an image.
The image used for examples n1 and 2 is as follows:
