How to draw arabic text on the image using `cv2.putText`correctly? (Python+OpenCV)

Question

I use python cv2(window10, python3.6) to write text in the image, when the text is English it works, but when I use Arabic text it writes messy code in the image.

Below is my code:

import cv2 
import numpy as np
blank_image = np.zeros((100,300,3), np.uint8)
font = cv2.FONT_HERSHEY_SIMPLEX 
org = (10, 50) 
fontScale = .5
color = (255, 0, 0)  
thickness = 1
blank_image = cv2.putText(blank_image, "اللغة العربية", org, font,  
                   fontScale, color, thickness, cv2.LINE_AA)
window_name = 'Image'
cv2.imshow(window_name, blank_image) 
cv2.waitKey(0)
cv2.destroyAllWindows()

the problem here blank_image = cv2.putText(blank_image, "اللغة العربية", org, font,
fontScale, color, thickness, cv2.LINE_AA)

I try it and the output not work .. maybe because of different language — OMRAN, Jan 24 '20 at 14:57
That module was likely only written to support English, and/or certain character codes. It probably uses the lower portion of the ASCII character set, not the whole extended set of unicode characters that were added over time. You'll need to find a module that was written to support the characters/languages you are interested in, or, if you have access to the source, perhaps you can modify it to extend the character set it knows about, or write your own module, or train some module on new data that fits your needs. Also check your character encoding. — SherylHohman, Jan 24 '20 at 20:29

fontpath = "arial.ttf" # <== download font
font = ImageFont.truetype(fontpath, 32)
img_pil = Image.fromarray(frame)
draw = ImageDraw.Draw(img_pil)
draw.text((50, 80),'عربي', font = font)
img = np.array(img_pil)
cv2.imshow(window_name, img)

import cv2 
import arabic_reshaper
from bidi.algorithm import get_display
import numpy as np
from PIL import ImageFont, ImageDraw, Image


cap = cv2.VideoCapture(0)

while(True):
    # Capture frame-by-frame
    ret, frame = cap.read()
    text = "ذهب الطالب الى المدرسة"
    reshaped_text = arabic_reshaper.reshape(text)
    bidi_text = get_display(reshaped_text) 
    fontpath = "arial.ttf" # <== https://www.freefontspro.com/14454/arial.ttf  
    font = ImageFont.truetype(fontpath, 32)
    img_pil = Image.fromarray(frame)
    draw = ImageDraw.Draw(img_pil)
    draw.text((50, 80),bidi_text, font = font)
    img = np.array(img_pil)

    cv2.imshow('window_name', img) 


    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

# When everything done, release the capture
cap.release()
cv2.destroyAllWindows()

Please provide an explanation how your code solves the problem. Cheers! — Quality Catalyst, Oct 04 '20 at 21:04

#before opening the programme
#first download arabic_reshaper lib write in Anaconda prompt
#"pip install arabic_reshaper"
#and download bidi lib write in Anaconda prompt 
#"pip install python-bidi"

import arabic_reshaper 
from bidi.algorithm import get_display
import numpy as np
from PIL import ImageFont, ImageDraw, Image
import cv2

img =cv2.imread("sun.jpg")
fontpath = "arial.ttf" # <== download font
font = ImageFont.truetype(fontpath, 32)
img_pil = Image.fromarray(img)
draw = ImageDraw.Draw(img_pil)
text="اللغة العربية"
reshaped_text = arabic_reshaper.reshape(text)
bidi_text = get_display(reshaped_text) 
draw = ImageDraw.Draw(img_pil)
