Hi everyone.

I use imrect to put a rectangle on a image.
Now, what I want to do is when I double-click this rectangle,
the image in this rectangle will be saved.

The problem is how to correspond the double-click event for
that rectangle.

Thanks in advanced.

From the help:

Example 2

Interactively place a rectangle by clicking and dragging. Use wait to
block the MATLAB command line. Double-click on the rectangle to resume
execution of the MATLAB command line.

figure, imshow('pout.tif');
h = imrect;
position = wait(h);
