Correct coordinates text in images With the same coordinates pos(x,y) subti

[D.LUFFY]

I have a text subtitle srt with coordinates example 270,270 video + sub srt

Result



When using "Pillow" or "opencv" or "tkinter" It gives you not the same coordinates. How can I get the same coordinates "{\pos(270,270)}Test" In the pictures above


Pillow

from PIL import Image, ImageDraw, ImageFont

# Load the image
image = Image.open("1.jpg")

# Create a drawing context
draw = ImageDraw.Draw(image)

# Define the text properties
font = ImageFont.truetype("Arial.ttf", 36)
text = "test"
text_color = (255, 255, 255)

# Calculate the position to center the text
text_length = draw.textlength(text, font)
x = 270
y = 270

# Add text to the image
draw.text((x, y), text, fill=text_color, font=font)

image.show()

Output

opencv

import cv2

myimg = "1.jpg"

img = cv2.imread(myimg)

f_face = cv2.FONT_HERSHEY_PLAIN
f_size = 1
f_color = (255,255,255)
f_thickness = 2
text = 'Test'
x,y = 270,270
img = cv2.putText(img, text, (x,y), f_face, f_size, f_color, f_thickness)

cv2.imshow("Test", img)
cv2.waitKey(0)
cv2.destroyAllWindows()

tkinter

import tkinter as tk
my_w = tk.Tk()
my_w.geometry("640x360")  # Size of the window 

l1=tk.Label(my_w,text='x=270,y=270',bg='yellow')
l1.place(x=270,y=270)

my_w.mainloop()  # Keep the window open

Does the pip modules give you the correct coordinates?

All three examples were actually working, it placed text in about that 270x270 mark.
And your results also, it is where it suppose to be, not at that posted "Test" mark.

So your question is how to make a player to force srt exactly to those coordinates?
Respecting:
1
00:00:00,000 --> 00:00:28,000
{\pos(270,270)}Test

I don't know, not sure if srt can do it at all, more like some animated format, I'm no expert though.

Many players do not respond to tags like that in SRT files. Especially outside a Windows computer. They are not part of the SRT specification.

https://en.wikipedia.org/wiki/.srt

For players that do support the \pos tag, I've found:

Players appear to use a scaling system where 0,0 is the top left of the frame, and ~400x300 is the bottom right. So the absolute location they appear depends on the frame size of the video.

The subs are drawn so that the center of the text (horizontally) and the bottom of the text (vertically) is at the specified location. So the absolute location they appear varies with the length and height of the text.

Thanks for the replies. I previously tried to create a script that gave the same wrong result.

I gave you all the information you need to calculate the x,y location in pixels from the x,y subtitle location.
