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.
Use normal button clicks to add points to the polyline. A shift-,
right-, or double-click adds a final point and ends the polyline selection.
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.


[x, y] = getline(fig)[x, y] = getline(ax)[x, y] = getline[x, y] = getline(...,'closed')


You can give an example if you know one.
