## Interactively measure pixel distances on raster layers

Pixie is a lightweight QGIS plugin for measuring pixel distances directly on raster images. It is particularly useful for workflows involving scanned maps or plans that need to be metricized using scale bars.

### Usage

- Select a raster layer in the layer panel.
- Activate Pixie from the toolbar.
- Click two points (e.g., ends of a scale bar).
- The pixel distance is displayed and copied to clipboard.

### Typical workflow

- Measure scale bar with Pixie
- Use value in metricize tool
- Proceed with analysis

### Notes

- Works in raster pixel space (not map units).
- Designed to integrate with Entropolis workflows.
