This sample demonstrates customization of the <a>Link</a> <a>Shape</a>'s <a>Geometry</a>.
|
||||
</p>
|
||||
<p>
|
||||
The TaperedLink class in this sample inherits from Link and overrides the makeGeometry method.
|
||||
For Bezier-curve Links, this computes a Geometry that is thick at the "from" end and thin at the "to" end.
|
||||
The implementation is very simple and does not account for links that
|
||||
are coming out from a node at angles that are not a multiple of 90 degrees.
