• Currently editing annotations only works for spline and polygon annotations.
• Freehand annotations due to the huge amount of polygon points cannot be edited in the same way.
• To implement alternative approach, where the user can use the a freehand tool-like edit function that allows the user to encircle the area they want to have cut out of the existing annotation.
  • Has to intersect the original annotation in 2 places

• Allow to import annotations from an export file (JSON).
• This should support single images or image frame sets.
• Validate annotation import (check that within image size, check file names for image frame sets)
• Option to purge existing/own annotations before import

In the current implementation of the canvas related components, the components state will be updated and then a setTimeout will delay the call to re-draw the canvas. This is unnecessary and not very robust. setState(stateUpdate, callback) offers the callback parameter to provide an event handler that gets executed after the state update is completed, which is exactly what the setTimeout tried to achieve.

This should be refactored in all components where it is used. Primarily the ImageAnnotation component.

• Allow user to add new control points between existing control points when polygon annotation edit mode.

When the user has decided to only show annotation boundaries / outlines, the outline should be drawn a bit thicker. The current thickness (1px) is insufficient and makes it harder to see annotations.

Display the filename of the image in the page.

The toolbar should have a switch to directly toggle the annotations, so the user can quickly have a glance at the original image without distractions due to overlapping annotations.
