I'm trying to create a box-like annotation, that represents a selected area in the image. But the box-annotation is only in 90°-steps rotatable.
I only can see two options here:
A: Create a box-shaped polyline.
B: Use 4 seperate lines.
Problem with the polyline is: I cannot select a polyline-point with the mouse and after a rotation the selection-box does not fit the object anymore. I would have to create my own "point-to-click", or is it possible to make a polyline-point selectable?
Problem with the 4 lines is: I would have to link all coordinates of all points and calculate the coordinates myself if one point moved - but there would be points to click.
Is there an easier option to create a free rotatable annotation-box?
