Print Text On Image Using Python OpenCV | OpenCV Tutorial

by Indian AI Production / On / In Uncategorized

In this tutorial, we are going to share code that prints any text on an image with a different style using the Python OpenCV library using the cv2.putText() function.

Syntax: cv2.putText(image, text, org, font, fontScale, color[, thickness[, lineType[, bottomLeftOrigin]]])

How to write Text on Image?

import cv2
import numpy as np

img_path = r"C:\Users\kashz\AI Life\AI Projects - IAIP, PTs (Web + Channel)\02 OpenCV\000 opencv tutorial\data\images\adult-beautiful-beauty-1464523.jpg"

image = cv2.imread(img_path)
image = cv2.resize(image, (1280, 720))

text = "Model"
org = (100, 200)
font = cv2.FONT_HERSHEY_COMPLEX
fontScale = 6
color = (0,0,255)  #(B, G, R)
thickness = 3
lineType = cv2.LINE_AA
bottomLeftOrigin = False

# Syntax>> cv2.putText(image, text, org, font, fontScale, color[, thickness[, lineType[, bottomLeftOrigin]]])

img_text = cv2.putText(image, text, org, font, fontScale, color, thickness, lineType, bottomLeftOrigin)

cv2.imshow("Text Image", img_text)

cv2.waitKey(0)
cv2.destroyAllWindows()

Print text Inverse

import cv2
import numpy as np

img_path = r"C:\Users\kashz\AI Life\AI Projects - IAIP, PTs (Web + Channel)\02 OpenCV\000 opencv tutorial\data\images\adult-beautiful-beauty-1464523.jpg"

image = cv2.imread(img_path)

image = cv2.resize(image, (1280, 720))

text = "Model"
org = (100, 200)
font = cv2.FONT_HERSHEY_COMPLEX
fontScale = 6

color = (0,0,255)  #(B, G, R)
thickness = 3
lineType = cv2.LINE_AA
bottomLeftOrigin = True

# cv2.putText(image, text, org, font, fontScale, color[, thickness[, lineType[, bottomLeftOrigin]]])
img_text = cv2.putText(image, text, org, font, fontScale, color, thickness, lineType, bottomLeftOrigin)


cv2.imshow("Text Image", img_text)

cv2.waitKey(0)
cv2.destroyAllWindows()

Print text with reflection

import cv2
import numpy as np

img_path = r"C:\Users\kashz\AI Life\AI Projects - IAIP, PTs (Web + Channel)\02 OpenCV\000 opencv tutorial\data\images\adult-beautiful-beauty-1464523.jpg"

image = cv2.imread(img_path)

image = cv2.resize(image, (1280, 720))

text = "Model"
org = (100, 200)
font = cv2.FONT_HERSHEY_COMPLEX
fontScale = 6

color = (0,0,255)  #(B, G, R)
thickness = 3
lineType = cv2.LINE_AA
bottomLeftOrigin = True

# cv2.putText(image, text, org, font, fontScale, color[, thickness[, lineType[, bottomLeftOrigin]]])
img_text = cv2.putText(image, text, org, font, fontScale, color, thickness, lineType, bottomLeftOrigin)

img_text = cv2.putText(image, text, org, font, fontScale, color, thickness, lineType, bottomLeftOrigin=False)

cv2.imshow("Text Image", img_text)

cv2.waitKey(0)
cv2.destroyAllWindows()

Text with different color and font with size

import cv2
import numpy as np

img_path = r"C:\Users\kashz\AI Life\AI Projects - IAIP, PTs (Web + Channel)\02 OpenCV\000 opencv tutorial\data\images\adult-beautiful-beauty-1464523.jpg"

image = cv2.imread(img_path)

image = cv2.resize(image, (1280, 720))

text = "Indian AI Production"
org = (50, 100)
font = cv2.FONT_HERSHEY_COMPLEX_SMALL
fontScale = 4

color = (87,67,23)  #(B, G, R)
thickness = 3
lineType = cv2.LINE_AA
bottomLeftOrigin = True

# cv2.putText(image, text, org, font, fontScale, color[, thickness[, lineType[, bottomLeftOrigin]]])
img_text = cv2.putText(image, text, org, font, fontScale, color, thickness, lineType, bottomLeftOrigin)

img_text = cv2.putText(image, text, org, font, fontScale, color, thickness, lineType, bottomLeftOrigin=False)

cv2.imshow("Text Image", img_text)

cv2.waitKey(0)
cv2.destroyAllWindows()

Font Style

//! Only a subset of Hershey fonts
enum HersheyFonts {
    FONT_HERSHEY_SIMPLEX        = 0, //!< normal size sans-serif font
    FONT_HERSHEY_PLAIN          = 1, //!< small size sans-serif font
    FONT_HERSHEY_DUPLEX         = 2, //!< normal size sans-serif font (more complex than FONT_HERSHEY_SIMPLEX)
    FONT_HERSHEY_COMPLEX        = 3, //!< normal size serif font
    FONT_HERSHEY_TRIPLEX        = 4, //!< normal size serif font (more complex than FONT_HERSHEY_COMPLEX)
    FONT_HERSHEY_COMPLEX_SMALL  = 5, //!< smaller version of FONT_HERSHEY_COMPLEX
    FONT_HERSHEY_SCRIPT_SIMPLEX = 6, //!< hand-writing style font
    FONT_HERSHEY_SCRIPT_COMPLEX = 7, //!< more complex variant of FONT_HERSHEY_SCRIPT_SIMPLEX
    FONT_ITALIC                 = 16 //!< flag for italic font
};
