A link of class IlvCrossingAwareLinkImage draws a gap at the
link crossings. The crossing graphic of the link fills this gap
with a bridge or tunnel shape. You can modify the size of the gap
using the method:
crossingAwareLinkImage.setGap(width);
The corresponding bridge or tunnel drawing
is automatically adapted when the gap changes.
The gap between links can follow the zoom
level or be independent of the zoom level. If the gap is zoomable,
its size changes as you zoom in and out of the view. If the gap is
nonzoomable, it remains constant during zooming. In particular with
nested graphers that have different zoom levels, it may be visually
more appealing if the gap is not zoomable.
To make gaps nonzoomable, call:
crossingAwareLinkImage.setGapZoomable(false);
Gaps are zoomable by default.
