# 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 |
|
|||
|
|

|
|||
|

|
|||
|
|
| distance | 5, 15, 30 |
|
|||
|
|

|

|
|||
|
|

|
|||
|
|
| 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.
