It makes no sense, it seems like a waste of time to me: once wasted time to implement, and again wasted time to clean up later on.- ? johnmu. I mean, on, the Google logo's alt text is "Google" and not "Google logo." But if you have a photo of someone and instead of saying in the alt text "Photo of name goes here" and you put in your company name - that is not helpful to you, your users, and to search engines.Īnd if you are trying to save time by doing this, all you are doing is wasting time, John added. If you just put in your company name, it does not describe the image, unless that is your company logo - I guess. The alt text for an image, by definition, is suppose to explain what the image is - it should describe the image for those who cannot see the image. John added not only does it make no sense, it would be a waste of time to do that. John Mueller from Google responded to that saying "it makes no sense" to do that. One SEO said his client wants to take a shortcut and autofill any blank alt text with his company name. I know a lot of SEOs work on this task but sometimes it is a lot of work. We covered the syntax of the cv2.putText() function along with various examples for a better understanding of beginners.Most sites I know do not fill in their image alt text for many images. Hope you found this quick tutorial on writing text on images in OpenCV quite helpful. Also Read – Learn to Draw Rectangle in OpenCV Python using cv2.rectangle() with Examples Conclusion.In the below example, we have created a black color rectangle and have written the text inside it by calculating the various coordinates.Ĭv2.rectangle(img3, (x,x), (x + w, y + h), (0,0,0), -1)Ĭv2.putText(img=img3, text="CAT",org=(x + int(w/10),y + int(h/1.5)), fontFace=cv2.FONT_HERSHEY_DUPLEX, fontScale=4, color=(255,0,0), thickness=7) We can create a small rectangle of the desired color on the image and put text on the rectangle. But there is a workaround for achieving this effect. OpenCV cv2.putText() does not have any built-in capabilities to have a background color for the text. In the below example, we split the text based on the newline character and then write each of the lines on the image in a loop.įor i, line in enumerate(text.split('\n')):Ĭv2.putText(img=img1, text=line, org=(150, y), fontFace=cv2.FONT_HERSHEY_SCRIPT_COMPLEX, fontScale=4, color=(255,255,0),Įxample – 3: Put Text with Background Color on Image in cv2.putText() We have to use certain workarounds to achieve this.
