I would like to show an image on GUI, and get the selected regions positions with getrect. But when i run my code i can draw a rectangle anywhere on the figure, but i want getrect to work only on axes1. How can i do that?
[file,path] = uigetfile('*.png');
if isequal(file,0)
disp('User selected Cancel');
else
disp(['User selected ', fullfile(path,file)]);
end
fullname=fullfile(path,file);
myimg=imread(fullname);
imshow(myimg);
rect = getrect;
x1 =rect(1);
x2 = x1 + rect(3);
y1 =rect(2);
y2 = y1 + rect(4);

Specify the axis handle in the first input
rect = getrect(ax)
However, getrect is outdated. Consider using
roi = drawrectangle(ax)
