QRCode XColor

Note: This does not work with the qrcode version 7.3.1 in pypi. pypi will not allow git sources in the setup.py requirments so mush be manually installed

Install qrcode from master branch

pip install git+https://github.com/lincolnloop/python-qrcode.git@8a37658d68dae463479ee88e96ee3f1f53a16f54

This library recreates a few of the moduledrawers classes already found in https://github.com/lincolnloop/python-qrcode.

This was done to greatly speed up the generation of creating colored qrcodes, as well as supporting for different colors and styles for the location marker in the corners.

Using these custom classes you do lose support for the full features of the color_mask argument in the original QRCode library like having the colors be a gradient across the qrcode.

I chose for speed over having that feature with still getting full color and transparency support of the qrcode.

All supported module drawers:

from qrcode_xcolor import (
    XStyledPilImage,
    XSquareModuleDrawer,
    XGappedSquareModuleDrawer,
    XCircleModuleDrawer,
    XRoundedModuleDrawer,
    XVerticalBarsDrawer,
    XHorizontalBarsDrawer
)

Here are some examples of the speed difference:

import time

import qrcode
from qrcode.image.styledpil import StyledPilImage
from qrcode.image.styles.moduledrawers import GappedSquareModuleDrawer, RoundedModuleDrawer
from qrcode.image.styles.colormasks import SolidFillColorMask

from qrcode_xcolor import XStyledPilImage, XGappedSquareModuleDrawer, XRoundedModuleDrawer

st = time.time()
qr = qrcode.QRCode()
qr.add_data("https://example.com")
img = qr.make_image(
    image_factory=StyledPilImage,
    color_mask=SolidFillColorMask(
        front_color=(59, 89, 152),
        back_color=(255, 255, 255),
    ),
    module_drawer=GappedSquareModuleDrawer(),
    eye_drawer=RoundedModuleDrawer(),
    embeded_image_path='docs/gitlab.png',
)
img.save("qrcode_color_mask.png")
print(f"qrcode color_mask: {time.time() - st:.4f}s")


st = time.time()
qr = qrcode.QRCode()
qr.add_data("https://example.com")
# The 4th value in all the colors is the opacity the color should use (0=clear <--> 255=solid)
img = qr.make_image(
    # Custom image factory
    image_factory=XStyledPilImage,
    back_color=(255, 255, 255, 255),  # Background color with opacity support
    module_drawer=XGappedSquareModuleDrawer(
        front_color=(59, 89, 152, 255),
    ),
    eye_drawer=XRoundedModuleDrawer(
        front_color=(255, 110, 0, 255),
        inner_eye_color=(65, 14, 158, 255),  # Only valid with the eye_drawer
    ),
    embeded_image_path='docs/gitlab.png',  # Still supports embedding logos in the middle
)
img.save("qrcode-xcolor.png")
print(f"qrcode-xcolor: {time.time() - st:.4f}s")

From this test we get the results (exact timings will vary but the difference is always there):

qrcode color_mask: 0.5071s

qrcode-xcolor: 0.0430s
