Here is a sample code: import cv2Įlif k=-1: # normally -1 returned,so don't print itĬv2.putText(img, chr(k), (i, 50), font, 1, (0, 255, 0), 1, cv2. For every character typed the image would be updated in a while loop.
#OPENCV WRITE TEXT ON IMAGE HOW TO#
I used the chr() function to enter the values of the keys being entered. In this tutorial, I will show you how to draw different style text on images using OpenCV library and Python coding. This function takes in the image, font, coordinates of where to put the text, color, thickness, etc.

#include "opencv2/imgproc.You can add text to your image using cv2.putText() functionĬv2.putText(img,'OpenCV',(10,500), font, 4, (255, 255, 255), 2, cv2.LINE_AA)Ĭv2.putText(im, 'Christmas', (10,450), font, 3, (0, 255, 0), 2, cv2.LINE_AA)Ĭv2.imwrite(path + 'pillar_text.jpg', im) Display text on an OpenCV window by using the function putText () OpenCV Python Server Side Programming Programming In this program, we will write text on an image using the opencv function putText (). ImageText.cpp #include "Imaging/imageText.h" Step 3: Pass the parameters in to the puttext () function. It was a PITA until I figured out that the import was messing up with my social life. Step 1: Import cv2 Step 2: Define the parameters for the puttext ( ) function.
#OPENCV WRITE TEXT ON IMAGE CODE#
The code compiled and linked fine however I was facing one weirdy behaviour with the putText (some garbage into my image). Steps: First we will create a image array using np.zeros () We will define a rectangle around the text using cv2.rectangle () After that we will put a text using cv2.putText () Then display the image using cv2.imshow () Wait for keyboard button press using cv2. Steps: First we will create a image array using np.zeros() We will define a rectangle around the text using cv2.rectangle() After that we will put a text. import numpy as np import cv2 image cv2.imread sample.png,cv2.IMREADUNCHANGED) position (10,50) cv2.putText ( image, numpy array on which text is written 'Python Examples', text position, position at which writing has to start cv2.FONTHERSHEYSIMPLEX, font family 1, font size (209, 80, 0, 255), font. Specify the font and draw the text using cv2.putText () cv2.putText.

Inside an infinite while loop, Display the image and use cv2.waitKey () for a keypress. Adding Text to Images: To put texts in images, you need specify following things. Firstly, import libraries and read the image then initialize the counter that will be used for changing the position of the text. My test code used only the putText sample above and I did included the imgproc.h just as I did into some of my oldcode. In this project, we will see how to write text on the image. One nasty detail that I saw into my test code: pay attention into the import stament - it is not displayed into most examples and it needs to be the right import.
