Hi all
i was playing with some functions like imrect and impositionrect and i wanted to ask if it is possible in the exapmle below provided by Matlab to get the new position of the rectangle in a matrix and then imediately update another function that depends on those values
figure, imshow('cameraman.tif');
h = imrect(gca, [10 10 100 100]);
addNewPositionCallback(h,@(p) title(mat2str(p,3)));
fcn = makeConstrainToRectFcn('imrect',get(gca,'XLim'),get(gca,'YLim'));
setPositionConstraintFcn(h,fcn);
