# Photoshop ExtendScript Dataset Generator

This folder contains JSX scripts to generate systematic layer-effect ground-truth images in Adobe Photoshop.

## Files

- `generate_inner_shadow_dataset.jsx` — Starter script for Inner Shadow.

## Usage

1. Open Adobe Photoshop.
2. Choose `File > Scripts > Browse...`.
3. Select `generate_inner_shadow_dataset.jsx`.
4. Choose an output folder when prompted.

Photoshop will create a new document for each parameter combination, draw a filled black rectangle, apply the Inner Shadow effect, and export a transparent PNG.

## Current parameter grid (short version)

| Parameter | Values |
|---|---|
| angle | 0, 90, 180, 270 |
| distance | 5, 15, 30 |
| size | 10, 30 |
| choke | 0, 20 |
| fx opacity | 75, 100 |
| fx blend mode | Normal, Multiply |

Total images: `4 × 3 × 2 × 2 × 2 × 2 = 192`.

## Notes

- Blend mode keys use Photoshop's 4-character codes (`Nrml`, `Mltp`).
- The output PNGs have transparent backgrounds, so MAE comparisons can ignore white reference pixels if needed.
- Opacity is passed as 0-100 (e.g. 75 means 75%).
- If a combination fails, the script alerts and continues with the next one.

## Next steps

- Add layer blend mode, layer opacity, and fill opacity variations.
- Extend to Drop Shadow, Outer Glow, Inner Glow, Stroke, Bevel & Emboss, Color Overlay.
