How to write text on a image in windows using python opencv2

Question

I want to put some text on an Image. I am writing the code as:

cv2.putText(image,"Hello World!!!", (x,y), cv2.CV_FONT_HERSHEY_SIMPLEX, 2, 255) 

It gives ERROR, saying 'module' object has no attribute 'CV_FONT_HERSHEY_SIMPLEX'

Query Can't I use the font type as above? I searched in internet, but found only the syntax related to to Opencv C++ for initFont. Then I thought of using putText to pass the font type as parameter. But it is not working for me.

Any suggestions?

This code uses cv2.putText to overlay text on an image. You need NumPy and OpenCV installed.

import numpy as np import cv2  # Create a black image img = np.zeros((512,512,3), np.uint8)  # Write some Text  font                   = cv2.FONT_HERSHEY_SIMPLEX bottomLeftCornerOfText = (10,500) fontScale              = 1 fontColor              = (255,255,255) thickness              = 1 lineType               = 2  cv2.putText(img,'Hello World!',      bottomLeftCornerOfText,      font,      fontScale,     fontColor,     thickness,     lineType)  #Display the image cv2.imshow("img",img)  #Save image cv2.imwrite("out.jpg", img)  cv2.waitKey(0)
