Python QR Code Generator
Generate common qr-code, artistic qr-code (black & white or colorized), animated qr-code (black & white or colorized).
# via pip
pip install amzqr(TIPS: If you haven't install amzqr, you should python(3) amzqr.py instead of amzqr blow.)

#1 Words
amzqr https://github.com- Just input a URL or a sentence, then get your QR-Code named 'qrcode.png' in the current directory.
#2 -v, -l
amzqr https://github.com -v 10 -l Q-
The default size of QR-Code depends both on the numbers of words you input and the level, while the default level (Error Correction Level) is H (the highest).
-
Customize: If you want to control the size and the error-correction-level, use the
-vand-larguments.-vrepresenting the length is from a minimum of 1 to a maximum of 40.-lrepresenting the error correction level is one of L, M, Q and H, where L is the lowest level and H is the highest.
#3 -n, -d
amzqr https://github.com -n github_qr.jpg -d .../paths/-
The default output-filename is 'qrcode.png', while the default output-directory is current directory.
-
Customize: You can name the output-file and decide the output-directory. Notice that if the name is as same as a existing file, the old one will be deleted.
-nrepresenting the output-filename could be in the format one of.jpg，.png，.bmp，.gif.-dmeans directory.
#1 -p
amzqr https://github.com -p github.jpg- The
-pis to combine the QR-Code with the following picture which is in the same directory as the program. The resulting picture is black and white by default.
#2 -c
amzqr https://github.com -p github.jpg -c- The
-cis to make the resulting picture colorized.
#3 -con, -bri
amzqr https://github.com -p github.jpg [-c] -con 1.5 -bri 1.6-
The
-conflag changes the contrast of the picture - a low number corresponds to low contrast and a high number to high contrast. Default: 1.0. -
The
-briflag changes the brightness and the parameter values work the same as those for-con. Default: 1.0.
The only difference from Artistic QR-Code mentioned above is that you should input an image file in the .gif format. The you can get your black-and-white or colorful qr-code. Remember that when you use -n to customize the output-filename, then the output-filename must end by .gif.
from amzqr import amzqr
version, level, qr_name = amzqr.run(
words,
version=1,
level='H',
picture=None,
colorized=False,
contrast=1.0,
brightness=1.0,
save_name=None,
save_dir=os.getcwd()
)details about each parameter are as mentioned above
# help(amzqr)
Positional parameter
words: str
Optional parameters
version: int, from 1 to 40
level: str, just one of ('L','M','Q','H')
picutre: str, a filename of a image
colorized: bool
constrast: float
brightness: float
save_name: str, the output filename like 'example.png'
save_dir: str, the output directory-
Use a nearly square picture instead of a rectangle one.
-
If the size of the picture is large, you should also choose a rightly large
-vinstead of using the default one. -
If part of the picture is transparent, the qr code will look like:
You can change the transparent layer to white, and then it will look like:
-
Numbers:
0~9 -
Letters:
a~z, A~Z -
Common punctuations:
· , . : ; + - * / \ ~ ! @ # $ % ^ & ` ' = < > [ ] ( ) ? _ { } | and (space)
