Description

The generic function move-line moves a line to a new location with end points specified by the coordinate arguments.

This automatically adjusts the geometry of the object, taking into account other constraints. Examples of such constraints are the label in a labelled-line-pinboard-object and the arrowhead in a arrow-pinboard-object.

The default value of redisplay is t, which means that the changed line is redrawn immediately. If you are moving many objects at the same time, it is useful to pass :redisplay nil.
