Starting in R2018b, a new set of ROI objects replaces the existing set of ROI objects. The new objects provide more functional capabilities, such as face color transparency. The new classes also support events that you can use to respond to changes in your ROI such as moving or being clicked. Although there are no plans to remove the old ROI objects at this time, switch to the new ROIs to take advantage of the additional capabilities and flexibility. For more information on creating ROIs using the new ROI functions, see Create ROI Shapes.
To specify whether the vertices of a polygon are draggable, assign a value to the
InteractionsAllowed
property of the
Polygon
ROI.
Update CodeUpdate all instances of setVerticesDraggable
method.
Discouraged Usage | Recommended Replacement |

This example uses
setVerticesDraggable to turn off the
capability of moving the vertices of a polygon to reshape
it. | Here is the equivalent code, creating a
Polygon ROI and replacing use of
setVerticesDraggable with setting the
value of the InteractionsAllowed property
to a value that doesn't provide reshaping abilities
('none' ). |
