lightflow-image-save

# LightFlow Image Save Use `lightflow.image_save` to copy a PNG image to a chosen output path. ## Workflow - Workflow id: `lightflow.image_save` - Runtime ownership: this workflow crate owns its public `execute()` entry and exposes it through the `lightflow-image-save-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.save`. - Input `image_path`: required source PNG path; artifact kind `image`; widget `image`. - 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_save -i image_path=./input.png -i output_path=./out.png ``` ## 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_save/run \ -H 'content-type: application/json' \ -d '{"inputs":{}}' ```
