image - Pillow Python (Watermarking) - Error Messages

Question

so I am trying to pick a folder, select every photo, watermark it with an individual text and safe it in a different folder. I have watched a lot of YouTube Videos and googled a lot but I can't help it anymore... Im always getting error messages and I can't see why.

So my current code is:

import PIL

from PIL import Image

from PIL import ImageDraw 
from PIL import ImageFont
import os

for f in os.listdir('.'):
    if f.endswith('.jpg'):
        i = Image.open(f)
        draw = ImageDraw.Draw(f)
        text = "Test, 22.01.2021"
        font = ImageFont.truetype("arial.ttf",75)
        textwidth, textheight = draw.textsize(text, font)
        width, height = f.size
        x=width/2-textwidth/2
        y=height-textheight-300
        draw.text((x,y), text, font=font)
    
        fn, fext = os.path.splitext(f)
        i.save('Test/{}.jpg'.format(fn))

Errors:

Maybe you guys can help me somehow?

Cheers

!!EDIT!!

after changing ..."Draw(f)" to "Draw(i) I do not get the same error messages but it still doesn't work.

Answer 1

You're using string as an argument to ImageDraw.Draw(). Use i variable instead of f.

i = Image.open(f)
draw = ImageDraw.Draw(i)
