# KissCut

PySide6 GUI for generating smooth kiss-cut outlines from PNGs. Drop an image, tune a few sliders (inflation, smoothing, corner detection), preview the padded mask, and export a spline-smoothed SVG.

## Features
- Drag-and-drop PNG preview with auto-padding when the mask touches an edge.
- Adjustable DPI, inflation (inches), alpha threshold, RDP epsilon, spline smoothing, spline points, and corner angle.
- Mask overlay plus Bezier-path preview in the viewport.
- SVG export of the smoothed outline (cubic Beziers).

## Requirements
- Python 3.9+ recommended.
- Dependencies: `Pillow`, `numpy`, `scikit-image`, `scipy`, `PySide6`.

Install deps:
```bash
pip install Pillow numpy scikit-image scipy PySide6
```

## Usage
1) Run the app:
```bash
python kisscut_gui.py
```
2) Drag a PNG into the window (or drop a file and hit “Update Preview”).
3) Tune sliders/inputs:
   - `DPI`: used for inflation and mm conversion.
   - `Inflation (inch)`: outward growth of the mask.
   - `Alpha Threshold`: what counts as transparent vs opaque.
   - `RDP Epsilon (mm)`, `Spline Smoothing`, `Spline Points`, `Corner Angle`: simplification and curve-fit controls.
4) Click “Export Vector” to save an SVG with the fitted outline.
