Interactive ROI Selection Tool #380
Description
Part of #373 Live plotting:
Build an interactive canvas drawing tool that allows users to select a Region of Interest (ROI) and automatically map those coordinate back to scan plan input fields
Goals
Acceptance criteria : What journeys should the user be able to complete to consider your feature done
Be as specific as you can, check them off once they work. Add more if you find more requirements during development. Issue should only be considered done after all of them are checked
- Canvas Drawing Interaction: The user can draw a selection box on the plotting canvas
- Form Auto-fill: The physical coordinates corresponding to the drawn ROI bounds automatically populate the scan range input fields.
Tasks
base on the goals, deduce the tasks required. check them off once they're done
Note
This is heavily depend on the core infrastructure direction.
- Davidia ROI Integration: Investigate if Davidia's built-in region selection tools can be leveraged for this.
- Interactive Canvas Drawing: Build box/polygon drawing tools on top of the active canvas layer.
- Inverse Matrix Mapping: Map drawn back to physical stage using the inverse transformation matrix.

to motor positions.
Because UI offsets become motor moves, this tool:
Needs deciding: does an ROI-driven move
go through the queue, or is there a separate direct path for interactive moves?
