Example 6 with DisplayIndependentPoint

use of org.eclipse.zest.layouts.dataStructures.DisplayIndependentPoint in project archi by archimatetool.

the class RadialLayoutAlgorithm method getLayoutBounds.

/**
 * Find the bounds in which the nodes are located.  Using the bounds against the real bounds
 * of the screen, the nodes can proportionally be placed within the real bounds.
 * The bounds can be determined either including the size of the nodes or not.  If the size
 * is not included, the bounds will only be guaranteed to include the center of each node.
