# mkmqr (MaKe Micro QR code)

This is a package to make micro QR codes.  
[日本語版のREADMEはこちら](https://github.com/tkamiya22/mkmqr/blob/release/0.6.0/docs/README-JA.md)


## Features

* Efficient encoding of text, use the most of the capacity of the symbol
* Automatically selects the best model from the text
* Maximizes the error correction level with the selected model number

Caution: When reading the micro QR code, please pay attention to security, for example, make sure the URL is correct.


## USAGE

### Command

Create a micro QR code from error correction level (optional) and text.

description of arguments

|                                 |   argument   |                      choice                       |    default     |
|--------------------------------:|:------------:|:-------------------------------------------------:|:--------------:|
| Required error correction level |     `-e`     | `x`(error detection only), `l`(L), `m`(M), `q`(Q) |      `x`       |
|          Path to save ths image |     `-p`     |                         -                         | `./(text).png` |
|                  Show the image |     `-s`     |                       `-s`                        |      none      | 
|                Specify encoding | `--encoding` |                         -                         |   shift-jis    |
|      Show debugging information |     `-d`     |           `-d`, `-dd`(more information)           |      none      |

### Program

```python
from mkmqr import (
    ErrorCorrectionLevel, create_symbol_image,
    InvalidCharacterError, InvalidPairError, OverCapacityError
)

try:
    image = create_symbol_image('demo', ErrorCorrectionLevel.M)
    image.show()
except OverCapacityError:
    print('Capacity is exceeded.')
except InvalidCharacterError:
    # By default, the final encoding is Shift-JIS.
    print('Unencodable characters are used.')
except InvalidPairError:
    # May be thrown if model number or other information is specified.
    print('The combination of the model or error correction level is incorrect.')
```
