Hi,
I'm trying to draw a shape (rectangle, circle etc.) to determine region of interest (ROI) in an image. When I use the drawrectangle function, I can get the corners of the first instance that the rectangle is drawn, however when I edit the rectangle on the figure (change size/position), it does not update the roi variable. How can I update the roi variable when the rectangle is altered in a script?
Code I use is below and I use R20109a;
temp = snapshot(cam1);
imshow(temp);
rect = drawrectangle;
roi = rect.Position;

You can try running the code in the loop for the required functionality
while true
%when you receive an update
x=input()
rect = drawrectangle;
%update roi
roi = rect.Position;
end
OR you can use Callbacks using App Designer.
