Set resize behavior of ROI object

setResizable is not recommended. With the new ROIs, use the InteractionsAllowed property instead. For more information, see Compatibility Considerations.



setResizable(h,TF) sets whether the ROI object may be resized interactively.


Fix Size of Ellipse

Create an ellipse ROI object. Specify a position constraint function using makeConstrainToRectFcn to keep the ellipse inside the boundary of the image.

h = imellipse(gca,[10 10 100 100]);
fcn = makeConstrainToRectFcn('imellipse',get(gca,'XLim'),get(gca,'YLim'));

Click and drag with the mouse to try resizing, reshaping, and moving the ellipse.

Now, disable resizing the ellipse.


Click and drag the ellipse again. You can move it, but not change the size or shape of it.
