Amazing-QR是一款基于 Python编写的二维码生成器。遵守GPL3.0开源协议。可生成普通二维码、带图片的艺术二维码(黑白与彩色)、动态二维码(黑白与彩色)。
使用方法:
普通二维码
#1 Words
amzqr https://github.com
在命令后输入链接或者句子作为参数,然后在程序的当前目录中产生相应的二维码图片文件,默认命名为” qrcode.png“。
#2 -v, -l
amzqr https://github.com -v 10 -l Q
默认边长是取决于你输入的信息的长度和使用的纠错等级;
而默认纠错等级是最高级的H。
自定义:如果想要控制边长和纠错水平就使用 -v 和 -l 参数。
-v 控制边长,范围是1至40,数字越大边长越大;
-l 控制纠错水平,范围是L、M、Q、H,从左到右依次升高。
#3 -n, -d
amzqr https://github.com -n github_qr.jpg -d .../paths/
默认输出文件名是“ qrcode.png “,而默认存储位置是当前目录。
自定义:可以自己定义输出名称和位置。注意同名文件会覆盖旧的。
-n 控制文件名,格式可以是 .jpg, .png ,.bmp ,.gif ;
-d 控制位置。
艺术二维码
#1 -p
amzqr https://github.com -p github.jpg
参数-p 用来将QR二维码图像与一张同目录下的图片相结合,产生一张黑白图片。
#2 -c
amzqr https://github.com -p github.jpg -c
加上参数 -c 可以使产生的图片由黑白变为彩色的。
#3 -con, -bri
amzqr https://github.com -p github.jpg [-c] -con 1.5 -bri 1.6
参数-con 用以调节图片的对比度,1.0 表示原始图片,更小的值表示更低对比度,更大反之。默认为1.0。
参数 -bri 用来调节图片的亮度,其余用法和取值与 -con 相同。
动态GIF二维码
动态二维码与上述的带图片的二维码的生成方法相同,只要采用 .gif 格式的图片即可生成黑白或者彩色的动态二维码。但注意如果使用了 -n 参数自定义输出的文件名,切记其格式也必须是 .gif 格式。

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
.
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:
