QR-Code

QR Code in Python

Python QR二维码生成器

It can generate common qr-code, black&white artistic qr-code, colorful artistic qr-code and animated qr-code.

可以生成普通二维码、黑白带图片的艺术二维码、彩色艺术二维码和动态二维码。

Example 示例

Usage 用法

Common QR-Code 普通QR二维码

python myqr.py  [-h] 
                [-v {1,2,3,...,40}] 
                [-l {L,M,Q,H}] 
                Words

• Use argument -h for help.

  使用参数 -h 来获得使用帮助。

  ​

#1 url
python myqr.py https://github.com

• Simplest way: Just input a URL or a sentence, then get your QR-Code in the current directory.

  最简单的用法：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QR二维码图片。

  ​

#2 -v, -l
python myqr.py https://github.com -v 10 -l Q

• The default length of a side of QR-Code depends on both the numbers of words you input. And the default level (Error Correction Level) is H (the highest).

  默认边长是取决于你输入的信息的长度，而默认纠错等级是最高级的H。

• Customize size: If you want to control the length and the error-correction-level, use the -v and -l arguments. The -v representing the length is from 1 to 40 that 1 means minimum and 40 means maximum. The -l representing the level is one of L, M, Q and H that L means lowest and H means highest.

  自定义尺寸：如果想要控制边长和纠错水平就使用 -v 和 -l 参数。使用 -v 来控制边长，范围是1至40，数字越大边长越大；使用 -l 来控制纠错水平，范围是L、M、Q、H，从左到右依次升高。

Artistic QR-Code 艺术QR二维码

python myqr.py  [-h] 
                [-v {1,2,3,...,40}] 
                [-l {L,M,Q,H}] 
                [-p picture_file] 
                [-c] 
                [-con contrast] 
                [-bri birghtness] 
                Words

• arguments -h, -v and -l is as mentioned above.

  参数 -h, -v 和 -l 如上文述。

  ​

#1 -p
python myqr.py https://github.com -p github.jpg

• The -p is to combine the QR-Code with the following picture which is at the same directory as the program. The resulting picture is black and white by default.

  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。

• Suggestion: If the size of the picture is large, you should choose a correct large -v too instead of using the default one.

  建议在图片尺寸大的时候使用 -v 的值也应该适当变大。

  ​

#2 -c
python myqr.py https://github.com -p github.jpg -c

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

  加上参数 -c 可以使产生的图片由黑白变为彩色的。

  ​

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

• The -con changes the contrast of the picture that 1.0 means original image, lower values mean less contrast and higher mean more. Default: 1.0.

  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。

• The -bri changes the brightness and the value is just like -con's.

  参数 -bri 用来调节图片的亮度，其余用法和取值与 -con 相同。

Animated GIF QR-Code 动态二维码

The only one difference from Artistic QR-Code mentioned above is that you should input a image file in the format .gif. The you can get your black-and-white or colorful qr-code.

动态二维码与上述的带图片的二维码的生成方法没什么区别，你只要采用 .gif 格式的图片即可黑白或者彩色的动态二维码。

Tips

• Use a square picture instead of a rectangle one.

  请采用正方形的图片

• If part of picture is transparent, the qr code will be like:

  You can change it into white, then be like:

  ​

  如果图片有透明无色部分，最终效果是：

  你可以将透明部分修改成白色，最终效果会变成
