Pillow pasting the original image instead of the cropped (circle) image

[VisualDevelopment]

What did you do?

I'm pasting an cropped image to another image.

What did you expect to happen?

Paste the cropped image.

What actually happened?

It pasted the original for some bizarre reason.

What are your OS, Python and Pillow versions?

• OS: Windows 10
• Python: 3.7.1
• Pillow: 5.0.3

Edit: Minimized code.

import os
from PIL import Image, ImageDraw, ImageOps, ImageFont, ImageFilter

filename = "image to crop.png"
offset = 50,50
size = 400,400
avatar = Image.open(filename)
avatar = avatar.resize(size, Image.ANTIALIAS)
rad = 200
circle = Image.new('L', (rad * 2, rad * 2), 0)
draw = ImageDraw.Draw(circle)
draw.ellipse((0, 0, rad * 2, rad * 2), fill=255)
alpha = Image.new('L', _avatar.size, "white")
w, h = _avatar.size
alpha.paste(circle.crop((0, 0, rad, rad)), (0, 0))
alpha.paste(circle.crop((0, rad, rad, rad * 2)), (0, h - rad))
alpha.paste(circle.crop((rad, 0, rad * 2, rad)), (w - rad, 0))
alpha.paste(circle.crop((rad, rad, rad * 2, rad * 2)), (w - rad, h - rad))
alpha = alpha.resize(size)
avatar.putalpha(alpha)
background = Image.open("image to paste to.png")
background.paste(avatar, offset)
background.save("image with cropped image pasted.png")

Thank you for the code example.

Please could you reduce it down to say, 10 or so essential lines that still reproduces the problem?

I shortened it @hugovk, please check my edit.

Which of the five pastes has the problem?

[VisualDevelopment]

The last one

[hugovk]

Here's a small working example:

from PIL import Image

red = Image.new("RGB", (200, 200), "red")
blue = Image.new("RGB", (200, 200), "blue")

# red.show()
# blue.show()

cropped_red = red.crop((0, 0, 10, 10))
blue.paste(cropped_red, (20, 20))

blue.show()

It creates this image:

but the red isn't circle 🤔

[VisualDevelopment]

i meant to crop it as a circle

[VisualDevelopment]

see, the file saved is cropped as a circle, but when i paste it, it pastes the original

[hugovk]

from PIL import Image, ImageDraw, ImageOps

big_size = (200, 200)
small_size = (20, 20)

red = Image.new("RGBA", big_size, "red")
blue = Image.new("RGBA", big_size, "blue")
mask = Image.new("L", big_size, 0)

draw = ImageDraw.Draw(mask)
draw.ellipse((0, 0) + small_size, fill=255)

cropped_red = ImageOps.fit(red, mask.size, centering=(0.5, 0.5))
cropped_red.putalpha(mask)
# cropped_red.show()

blue.paste(cropped_red, small_size, mask)

blue.show()

oh thanks

[VisualDevelopment]

OMG IT WORKED THANK YOU SO MUCH!

[hugovk]

You're welcome!

epic

[hugovk]

Nice!

@hugovk When i crop an transparent image it appears with a black background, how do i fix this?

Please share the code you're using, again please follow the "Minimal, Complete, and Verifiable" guidelines: https://stackoverflow.com/help/mcve

[VisualDevelopment]

i haven't changed it at all

[VisualDevelopment]

it's still the same

If anyone wondering what the answer had did, it's basically passing the mask into the paste() as well

This line:

blue.paste(cropped_red, small_size, mask)

this is it, thank you so much!
