Common QR-Code

#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 -v and -l arguments.
-v representing the length is from a minimum of 1 to a maximum of 40.
-l representing 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.
-n representing the output-filename could be in the format one of .jpg， .png ，.bmp ，.gif .
-d means directory.

Artistic QR-Code

#1 -p
amzqr https://github.com -p github.jpg

The -p is 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 -c is to make the resulting picture colorized.

#3 -con, -bri
amzqr https://github.com -p github.jpg [-c] -con 1.5 -bri 1.6

The -con flag changes the contrast of the picture - a low number corresponds to low contrast and a high number to high contrast. Default: 1.0.

The -bri flag changes the brightness and the parameter values work the same as those for -con. Default: 1.0.

Animated GIF QR-Code

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.
Import Way
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

Tips

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 -v instead 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:
