WebTrackbar arguments are always integer and they always start at 0. However, for lines the smallest line thickness is 1. Therefore we use the max function to make the thickness at least 1. To have a numeric feedback, we display the thickness value also in the overlay: def trackbar(x): x = max(1, x) cv.displayOverlay('window', f'thickness={x}') WebWe have set the color of the line segment as red by passing a tuple of values (255,0,0) and have set the thickness to 5. # Importing OpenCV import cv2 # Importing numpy import numpy as np # Importing matplotlib.pyplot import matplotlib.pyplot as plt # Creating a blank image to work with blank_img = np.zeros(shape=(512,512,3), dtype=np.int16) # … how many calories in half cup of jasmine rice https://andygilmorephotos.com
