## Installation
### pip
```bash
pip install jdeskew
```
## How-to-use
### using python
```python
from jdeskew.estimator import get_angle
angle = get_angle(image)
from jdeskew.utility import rotate
output_image = rotate(image, angle)
```
### Docker
https://hub.docker.com/r/phamquiluan/jdeskew/tags
```bash
# build
DOCKER_BUILDKIT=1 docker build -t jdeskew .
# run
docker run -p 8000:80 jdeskew
# test
curl -v -F [email protected] localhost:8000/predict
```
### using cog
https://github.com/replicate/cog
```bash
cog build --debug
cog predict -i [email protected]
# Output:
# Running prediction...
# {
# "angle": -0.12520868113522532
# }
```
