## Install

```python
# via pip
pip install amzqr
```

## Usage

### Terminal Way  

*(**TIPS**: If you haven't install [**amzqr**](https://pypi.python.org/pypi/amzqr), you should  `python(3) amzqr.py` instead of `amzqr` blow.)*

```sh
# summary
amzqr Words
      [-v {1,2,3,...,40}]
      [-l {L,M,Q,H}]
      [-n output-filename]
      [-d output-directory]
      [-p picture_file]
      [-c]
      [-con contrast]
      [-bri brightness]
```

- see [Common QR-Code](#common-qr-code) for `Words`, `-v`, `-l`, `-n`, `-d`
- see [Artistic QR-Code](#artistic-qr-code) for `-p`, `-c`, `-con`, `-bri`
- see [Animated GIF QR-Code](#animated-gif-qr-code) about GIF

#### Common QR-Code

![](https://github.com/hwxhw/amazing-qr/blob/master/example/0.png)

```markdown
#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.


```markdown
#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.




```markdown
#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

![](https://github.com/hwxhw/amazing-qr/blob/master/example/1.png)![](https://github.com/hwxhw/amazing-qr/blob/master/example/2.png)


```markdown
#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.


```markdown
#2 -c
amzqr https://github.com -p github.jpg -c
```

* The `-c` is to make the resulting picture **colorized**.



```markdown
#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

![](https://github.com/hwxhw/amazing-qr/blob/master/example/daftpunktocat-guy_qrcode.gif)![](https://github.com/hwxhw/amazing-qr/blob/master/example/daftpunktocat-guy_qrcode0.gif)

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

```python
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](#terminal-way)*


```python
# 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: ![](https://github.com/hwxhw/amazing-qr/blob/master/example/aa.png)

  You can change the transparent layer to white, and then it will look like: ![](https://github.com/hwxhw/amazing-qr/blob/master/example/a0.png)

## Supported Characters

* Numbers:  `0~9`

* Letters:  `a~z, A~Z`

  ```console
