## Overview |
|||
|
|||
Sign and scan a PDF file without actually having to print out the PDF (or scan it). |
|||
|
|||
## How to use |
|||
|
|||
1. Prerequisites |
|||
|
|||
If you're on Debian (Ubuntu) Linux: |
|||
|
|||
```shell |
|||
$ apt install imagemagick |
|||
$ pip3 install towhee |
|||
``` |
|||
|
|||
If you're on MacOS: |
|||
|
|||
```shell |
|||
% brew install imagemagick |
|||
% pip3 install towhee |
|||
``` |
|||
|
|||
2. Run it |
|||
|
|||
```python |
|||
>>> from towhee import pipeline |
|||
>>> p = pipeline('fzliu/sign-and-scan') |
|||
>>> p('/path/to/lease.pdf', '/path/to/output.pdf', '/path/to/signature/file.jpg', x_offset, y_offset) |
|||
``` |
|||
|
|||
Enjoy! |
