Shape grouping

Grouping multiple shapes during annotation.

This feature allows us to group several shapes.

You may use the Group Shapes button or shortcuts:

  • G — start selection / end selection in group mode
  • Esc — close group mode
  • Shift+G — reset group for selected shapes

You may select shapes clicking on them or selecting an area.

Grouped shapes will have group_id filed in dumped annotation.

Also you may switch color distribution from an instance (default) to a group. You have to switch Color By Group checkbox for that.

Shapes that don’t have group_id, will be highlighted in white.
