PixPick v0.2.1 – API Refinements & MultiPolygon Enhancements

🌟 Summary

PixPick v0.2.1 focuses on API consistency, improved geometry utilities, expanded MultiPolygon support, better test coverage, and documentation improvements. This release standardizes adapters across selectors by exposing them as properties, adds new convenience properties to the Line and MultiPolygon classes, and improves the contributor experience with clearer documentation and guidelines.

📊 Key Changes

• ✨ Standardized selector adapters by converting adapter methods (e.g. sam, yolo_region, raw) into properties for a cleaner and more Pythonic API.
• 📐 Added start, end, and vector properties to the Line class.
• 🔷 Enhanced MultiPolygon with additional properties and improved polygon data handling.
• 🧪 Added a reusable make_polygon fixture to simplify and improve test flexibility.
• 📚 Updated documentation to reflect the new property-based API, added Line selector documentation, improved the roadmap, and clarified contribution guidelines.
• 🔧 General maintenance, documentation refinements, and release preparation.

PixPick v0.2.0 – Multi-Region Selection

🌟 Summary

PixPick v0.2.0 introduces one of the most requested features: multi-region selection. You can now draw and manage multiple bounding boxes and polygons within a single session, making interactive region selection significantly more efficient for computer vision workflows.

---

📊 Key Changes

• ✨ Added support for selecting multiple bounding boxes
• ✨ Added support for selecting multiple polygons
• ⚡ Improved the interactive selection workflow for multi-region use cases
• 🛠️ General bug fixes and internal improvements

---

🎯 Purpose and Impact

Many computer vision applications require working with multiple regions in the same image. Previously, users had to restart the selection process for every new region.

With v0.2.0, PixPick enables seamless multi-region selection, reducing repetitive interactions and improving productivity for tasks such as:

• Object Detection (YOLO)
• YOLOE visual prompt
• SAM / SAM2 prompts
• Region-based analytics
• OpenCV applications
• Supervision PolygonZone

This release makes PixPick a more efficient utility for developers building interactive computer vision pipelines.

What's Changed

New Features

• Support for selecting multiple bounding boxes in a single interaction.
• Support for selecting multiple polygons in a single interaction.
• Improved APIs for handling collections of selected regions.

Improvements

• Enhanced selection experience for multi-region workflows.
• Internal code cleanup and stability improvements.
• More detailed docs about drawing control keys
• Separate color for box, polygon and line
