import cv2 | |
# open an image using opencv | |
imgOriginal = cv2.imread('Office.jpg') | |
img = cv2.resize(imgOriginal, (640, 304)) | |
cv2.imshow('@ElBruno - Office', img) | |
# get image height and width | |
height, width, channels = img.shape | |
# add watermark | |
white = (255, 255, 255) | |
position = (width - 125, height - 15) | |
font = cv2.FONT_HERSHEY_DUPLEX | |
cv2.putText(img, "@El Bruno", | |
position, font, 0.7, white, 1) | |
cv2.imshow('@ElBruno - Watermark', img) | |
# save image using opencv | |
cv2.imwrite('OfficeWatermark.jpg', img) | |
# key controller | |
cv2.waitKey(0) | |
cv2.destroyAllWindows() |
Happy coding!
