Returns information about the currently displayed image based on a use supplied mouse-click. The general syntax for its use is
y = point
The returned vector y
has three elements:
where
r,c
are the row and column coordinates of the scalar image selected
by the user, and v
is the value of the scalar image at that point. Image
zoom is automatically compensated for, so that r,c
are the coordinates into
the original matrix. They will generally be fractional to account for the
exact location of the mouse click.
