Possibility to add a logo in the middle

[TWEagle]

Is it possible to add an image in the center of the qr-code?

[stvnmbt]

Yes. From https://github.com/lincolnloop/python-qrcode#styled-image

import qrcode
from qrcode.image.styledpil import StyledPilImage
from qrcode.image.styles.moduledrawers.pil import RoundedModuleDrawer
from qrcode.image.styles.colormasks import RadialGradiantColorMask

qr = qrcode.QRCode(error_correction=qrcode.constants.ERROR_CORRECT_L)
qr.add_data('Some data')

img_1 = qr.make_image(image_factory=StyledPilImage, module_drawer=RoundedModuleDrawer())
img_2 = qr.make_image(image_factory=StyledPilImage, color_mask=RadialGradiantColorMask())
img_3 = qr.make_image(image_factory=StyledPilImage, embeded_image_path="/path/to/image.png") # this is what you want

Is there a way to control the relative size of the image? E.g., I want the width of the logo to be 40% the width of the QR code.

Is there a way to control the relative size of the image?

Yes, with pull request #360 this is now possible. Simply set embeded_image_ratio with a value between 0 and 1. Default is 0.25.

Thanks! I will try it out with the next release.
FWIW, I don't know why I put my question in this issue. Seems separate. Either way, this issue can probably be closed.

I seems that you need to turn up the error correction in order for QR codes with images in the middle to work?

[lsgd]

That's correct.
If you generate the QR code with an image and without an image, you will see that the QR code is the same except that the image crops out some part.

Because the image removes some information you need to use a higher error correction.
Note, that if the added image is too large even the highest error correction might not be sufficient anymore.
