opencv line
import cv2
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 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 line. The coordinates are represented as tuples of two values i.e. (X coordinate value, Y coordinate value).
# color: It is the color of line to be drawn. For BGR, 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.
