LightFlow Image Invert
Use this skill to invert the colors of a PNG image generated or referenced by a LightFlow workflow.
Workflow
- Workflow id:
lightflow.image_invert
- 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.
- Output
image_path: inverted PNG path; artifact kind image.
- Output
image: image artifact metadata; artifact kind image.
Pipeline Usage
Quote or escape the pipe token so the shell passes it to lfw:
lfw run lightflow.text_to_image \
-i prompt='"a small cat photo"' \
-i output_path='"out/cat.png"' \
'|' lightflow.image_invert \
-i output_path='"out/cat-inverted.png"'
The second stage receives the first stage outputs as inputs. Set output_path
on the invert stage to avoid writing beside the source image.
API Usage
Start lfw serve, then call the workflow through the shared HTTP run contract. Adjust inputs to match the workflow contract above.
curl -sS -X POST http://127.0.0.1:5174/workflows/lightflow.image_invert/run \
-H 'content-type: application/json' \
-d '{"inputs":{}}'
