MATLAB: Imrect assigning values to

Question

Hello. Im using a user defined rectangle to define a ROI on a tiff image.

           p=[760,1660,500,500]
           h = imrect(handles.axes1, p) 
           p = wait(h);
           p = h.getPosition();
           assignin('base','p',round(p))
           addNewPositionCallback(h,@(p)assignin('base','p',p));

I am using guide, and want the ability to enter the values in "p" from a text box. Can I just create the string and assign it to "p"?

thanks Jason

Sure, no problem.

str = get(handles.editX1, 'string');
leftColumn = str2double(str);
str = get(handles.editWidth, 'string');
width = str2double(str);
str = get(handles.editY1, 'string');
topRow = str2double(str);
str = get(handles.editHeight, 'string');
height = str2double(str);
p = [leftColumn, topRow, width, height];
