# LightFlow Image Crop
Use `lightflow.image_crop` to crop a rectangular region from a PNG image.
## Workflow
- Workflow id: `lightflow.image_crop`
- Runtime ownership: this workflow crate owns its public `execute()` entry and exposes it through the `lightflow-image-crop-runner` package binary.
- Host engine: `package.command.v1`; discovery, help, and plan do not execute package source.
- Input values are validated against their declared JSON types without string coercion.
- Runtime: `lightflow.image.crop`.
- Input `image_path`: required source PNG path; artifact kind `image`; widget `image`.
- Inputs `x`, `y`, `width`, and `height`: crop rectangle; widget `number`.
- Input `output_path`: optional destination PNG path; artifact kind `image`; widget `file_save`.
- Outputs `image` and `image_path`; artifact kind `image`.
## Usage
```bash
lfw run lightflow.image_crop -i image_path=./input.png -i x=0 -i y=0 -i width=512 -i height=512
```
## API Usage
Start `lfw serve`, then call the workflow through the shared HTTP run contract. Adjust `inputs` to match the workflow contract above.
```bash
curl -sS -X POST http://127.0.0.1:5174/workflows/lightflow.image_crop/run \
-H 'content-type: application/json' \
-d '{"inputs":{}}'
```
