imoverview() - Image Processing

imoverview(himage) creates
an Overview tool associated with the image specified by the handle himage,

a separate figure window that displays the target image in its entirety,
scaled to fit. Over this scaled version of the image, the tool draws
a rectangle, called the detail rectangle, that shows the portion of
the target image that is currently visible in the scroll panel. To
view portions of the image that are not currently visible in the scroll
panel, move the detail rectangle in the Overview tool.The following figure shows the Image Tool with the Overview

hIm = imshow('tape.png');
hSP = imscrollpanel(hFig,hIm);
api = iptgetapi(hSP);
api.setMagnification(2) % 2X = 200%
