# Photopea / Photoshop ExtendScript Dataset Generator
|
|||
|
|
|
|||
|
|
This folder contains JSX scripts to generate systematic layer-effect ground-truth images in Photopea or Photoshop.
|
|||
|
|
|
|||
|
|
## Files
|
|||
|
|
|
|||
|
|
- `generate_inner_shadow_dataset.jsx` — Short starter script for Inner Shadow.
|
|||
|
|
|
|||
|
|
## Usage
|
|||
|
|
|
|||
|
|
1. Open Photopea (https://www.photopea.com) in a browser.
|
|||
|
|
2. Press `Alt+Ctrl+I` (or use `File > Automate > Script`) to open the script runner.
|
|||
|
|
3. Paste the contents of the desired `.jsx` file and run it.
|
|||
|
|
4. Select an output folder when prompted.
|
|||
|
|
|
|||
|
|
Photopea will create a new document for each parameter combination, draw a black rectangle, apply the Inner Shadow effect, hide the background, 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.
|
|||
|
|
- ExtendScript error handling is basic; if a parameter combination fails, the script logs it and continues.
|
|||
|
|
|
|||
|
|
## Next steps
|
|||
|
|
|
|||
|
|
- Add more layer blend modes, fill opacity, and layer opacity variations.
|
|||
|
|
- Extend to Drop Shadow, Outer Glow, Inner Glow, Stroke, Bevel & Emboss.
|
|||
|
|
- Add a companion Rust generator that creates matching PSD files so the same dataset can be imported back into HCIE for MAE tuning.
