The Pixel Region tool is a uipanel object that contains an extreme
close-up view of a small region of pixels in the target image. If
the size of the pixels allows, the tool superimposes the numeric value
of the pixel over each pixel. To define the region being examined,
the tool overlays a rectangle on the target image, called the pixel
region rectangle. To view pixels in a different region, click and
drag the rectangle over the target image. See
To create a Pixel Region tool in a separate figure window, use
himage = imshow('peppers.png'); hfigure = figure; hpanel = impixelregionpanel(hfigure, himage);
Set the panel's position to the lower-left quadrant of the figure.
