[MSD-715] Display feature marker where user clicks and improve feature movement handling - #3554
Conversation
There was a problem hiding this comment.
Pull request overview
This PR updates the cryo-FIBSEM feature workflow so the feature marker (and milling-pattern anchor) is displayed and persisted at the user-clicked location within the saved FIB reference image, rather than implicitly assuming the image center.
Changes:
- Introduces and persists a per-feature
milling_feature_offset(relative to the saved FIB reference image center). - Updates UI/controllers/overlay drawing to use the offset for marker placement and for moving the milling-pattern anchor.
- Adds/extends tests to cover offset persistence and propagation to milling tasks.

A pending offset tracks unsaved marker movement. Shared setters update feature state and milling pattern centres. Project save and load preserve committed offsets. Reference-image acquisition preserves the physical feature position and recalculates the offset. The overlay uses offset-based positions for editing, hit detection, and drawing. Milling controllers route position changes through the shared feature state. Sequence Diagram(s)sequenceDiagram

milling posture remains at the reference-image centre. Apply only the shared

- Around line 450-455: Update the keyboard movement logic in on_char to
calculate the next position from feature.milling_feature_offset and apply it
through feature.set_milling_feature_offset(...), rather than writing
pattern.center.value directly. Preserve the existing movement increments and
ensure the overlay marker and serialized offset follow keyboard moves.

@ilyushkin the one thing I'm not certain about is the behaviour when changing the position of a feature after a "position has been saved" (aka, it has a milling_feature_offset). I don't think there is much case where the user would want to discard the new position (unless this was really a mistake, but we should handle it by supporting "undo", instead). As I understand, this would happen mostly because the user wants to more precisely point a position of the feature based on the FIB image. In such case, the user wouldn't want to discard the position, nor acquire another FIB image. They would just want to have the current FIB image still be used as the reference image. If so, wouldn't it make more sense to just automatically recalculate the milling_feature_offset after moving the feature? |
