getline() - Image Processing

[x, y] = getline(fig) lets
you select a polyline in the current axes of figure fig using
the mouse. Coordinates of the polyline are returned in X and Y.

Pressing Return or Enter ends
the polyline selection without adding a final point. Pressing Backspace or Delete removes
the previously selected point from the polyline.[x, y] = getline(ax) lets
you select a polyline in the axes specified by the handle ax.[x, y] = getline is the
same as [x,y] = getline(gcf).[x, y] = getline(...,'closed') animates
and returns a closed polygon.
