setResizable

Set resize behavior of ROI object

setResizable is not recommended. Use one of the ROI classes instead, described in ROI Creation Overview.

Syntax

setResizable(h,TF)

Description

example

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

Examples

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.

imshow('coins.png')
h = imellipse(gca,[10 10 100 100]);
fcn = makeConstrainToRectFcn('imellipse',get(gca,'XLim'),get(gca,'YLim'));
setPositionConstraintFcn(h,fcn);

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

Now, disable resizing the ellipse.

setResizable(h,false);

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

Input Arguments
