In this program, we will write text on an image using the opencv function putText(). This function takes in the image, font, coordinates of where to put the text, color, thickness, etc.

Original Image

Algorithm

Step 1: Import cv2
Step 2: Define the parameters for the puttext( ) function.
Step 3: Pass the parameters in to the puttext() function.
Step 4: Display the image.

Example Code

import cv2
image = cv2.imread("testimage.jpg")
text = "TutorialsPoint"
coordinates = (100,100)
font = cv2.FONT_HERSHEY_SIMPLEX
fontScale = 1
color = (255,0,255)
thickness = 2
image = cv2.putText(image, text, coordinates, font, fontScale, color, thickness, cv2.LINE_AA)
cv2.imshow("Text", image)
