makeConstrainToRectFcn() - Image Processing

fcn = makeConstrainToRectFcn(type, xlim, ylim) creates
a position constraint function for draggable tools of a given type,
where type is one of the following strings:  'imellipse', 'imfreehand', 'imline', 'impoint', 'impoly',
or 'imrect'. The rectangular boundaries of the
position constraint function are described by the vectors xlim and ylim where xlim
= [xmin xmax] and ylim = [ymin ymax].

Syntax

fcn = makeConstrainToRectFcn(type, xlim, ylim)

Example

figure, plot(1:10);
h = impoint(gca,2,6);
api = iptgetapi(h);
fcn = makeConstrainToRectFcn('impoint',get(gca,'XLim'),...
   get(gca,'YLim'));
api.setPositionConstraintFcn(fcn);
