如何在Python的qrcode中心插入徽标？

Question

我在python中使用pyqrcode模块并使用它生成QR代码.如何将徽标放在QR码的中心.

代码看起来像这样

import pyqrcode
data = "Hello World!!"

number = pyqrcode.create(data)
number.png('xyz.png', scale=int(scale))

with open('xyz.png', "rb") as f:
    return HttpResponse(f.read(), content_type="image/png")

或者有没有其他方法来做这个而不是pyqrcode？

Answer 1

虽然这个问题已经存在一年多了，但我仍然发布我的解决方案，因为我希望它可以帮助其他人。

注意我生成了 png 格式的二维码图像。要使其正常工作，pypng必须安装模块。

import pyqrcode
from PIL import Image

# Generate the qr code and save as png
qrobj = pyqrcode.create('https://stackoverflow.com')
with open('test.png', 'wb') as f:
    qrobj.png(f, scale=10)

# Now open that png image to put the logo
img = Image.open('test.png')
width, height = img.size

# How big the logo we want to put in the qr code png
logo_size = 50

# Open the logo image
logo = Image.open('stackoverflow-logo.jpg')

# Calculate xmin, ymin, xmax, ymax to put the logo
xmin = ymin = int((width / 2) - (logo_size / 2))
xmax = ymax = int((width / 2) + (logo_size / 2))

# resize the logo as calculated
logo = logo.resize((xmax - xmin, ymax - ymin))

# put the logo in the qr code
img.paste(logo, (xmin, ymin, xmax, ymax))

img.show()

Answer 2

import pyqrcode
from PIL import Image
url = pyqrcode.QRCode('http://www.eqxiu.com',error = 'H')
url.png('test.png',scale=10)
im = Image.open('test.png')
im = im.convert("RGBA")
logo = Image.open('logo.png')
box = (135,135,235,235)
im.crop(box)
region = logo
region = region.resize((box[2] - box[0], box[3] - box[1]))
im.paste(region,box)
im.show()
