How to use getrect only for axes1?

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However, getrect is outdated.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)

I tried using drawrectangle(ax) and it worked, but now i cannot get the xi yi coordinates of the rectangle.

position = roi.Position;
x1 = position(1);
x2 = x1 + position(3);
y1 = position(2);
y2 = y1 + position(4);

@guanin hae, take a few minutes to read through the drawrectangle link I provided in my answer. You'll quickly learn the answer to your question.
