Hi everyone,
I'm trying to make a rectangle to define a region of interest in an image. I used the imrect function in Matlab. Now I want to make a dashed line of the top, bottom and right line of this rectangle, the left one should still be continuous. I wanted to do this with imline, but I don't know how to make this line dashed. I can't use the line function, because the rectangle has to be draggable and reseizable.
I hope someone can help me with this problem.
Thanks in advance.
Ellen

Something like this would help you make a dashed line using imline .
h = imline();
h1 = get(h,'Children');
set(h1(3),'LineStyle','--');
set(h1(4),'LineStyle','--');
