# Image Processing

Generate a task-specific Pillow script under `<temp-dir>`. This skill does not bundle a CLI.

```text
uv run --with Pillow <temp-dir>/image-task.py
```

## Safety

- Inspect source dimensions, mode, format, and animation first
- NEVER overwrite originals without explicit user intent
- Write transformed files to explicit output paths
- Preserve animation only when the requested format supports it
- Test batch logic on one representative file first

## Required follow-up reads

|Need|Read|When|
|---|---|---|
|Pillow setup, format choice, and implementation patterns|`references/pillow-patterns.md`|Before writing the task-specific script|

## Workflow

1. Resolve input and output paths with `pathlib.Path`
2. Inspect images with `Image.open()` before transformation
3. Select the smallest matching pattern from `references/pillow-patterns.md`
4. Write a task-specific script under `<temp-dir>`
5. Run it through the documented `uv` command
6. Re-open outputs and verify dimensions, mode, and format
