Point annotation tool #564
Description
DISCLAIMER: This ticket is the first ticket for shape annotations and the design decisions must allow for an easy extension for new shapes (bounding boxes, arrows, text) regarding export/saving, datastructure, adding/deleting/moving shapes.
As a user I want to have a tool which allows me to make point annotations.
Description
This ticket includes adding a new toolbox category for shape annotations. These could be points (this ticket), bounding boxes or shapes (arrows, text, etc.).
On click in the editor, a new point is added.
Think about
- how to remove points (right click, delete key?)
- how to move points around? E.g. have a cross symbol with arrows when hovering over a point, that allows to drag the point around.
- how to export a file containing multiple points on different annotation layers (or even groups) --> how do other services handle these (e.g. radiology editors), maybe as CSV?
Data structure
- x, y, slice (z) coordinates
- reference to annotation layer, that determines the color of the point
Acceptance Criteria
- have a point annotation tool
- allow to delete points
- allow to move points
- it is possible to have different colored points on different annotation layers
- disable point annotations for MIA Review
