MindFusion.Diagramming for WinForms Professional 6.8.0

Improves user interaction and rendering speed for diagrams containing tens of thousands of items.

Features

• Spatial index - Set the EnableSpatialIndex property of the Diagram to create an index of item positions for faster hit-testing and viewport clipping queries. This should greatly improve user interaction and rendering speed for diagrams containing tens of thousands, or more, items.
  • Note that rendering speed improves only when showing a smaller part of the diagram inside DiagramView's viewport.
• Pattern router - New PatternRouter class, routes links by applying patterns of segment and turn sequences and accepting them when resulting paths do not cross nodes:
  • A path is accepted if its final segment ends in a target point and is orthogonal to the respective side of the target node. If there are several possible paths, the router selects the shortest one.
  • The MinimumDistance property specifies a minimum allowed distance of link segments from nodes.
  • The PreferredDistance property specifies a distance of first or last link bend from the associated node.
  • PatternRouter includes several predefined patterns designed to create consistent-looking paths, and allows the creation of custom patterns.
  • Custom patterns can be defined as a sequence of RouteStep objects specifying whether the path advances by relative or absolute distance, or changes direction.
• Composite router - The CompositeRouter class lets you chain link routers (objects implementing ILinkRouter interface) so that a link passes through the sequence until it gets routed successfully.
  • Diagram's default router is now set to a CompositeRouter instance containing a PatternRouter and GridRouter sequence. This applies several standard pattern paths when possible, and otherwise routes links using the cost minimizing heuristics-based grid router.
• API changes
  • Suspend and Resume methods have been removed from ILinkRouter.
    (Call Diagram's SuspendLinkRouter and ResumeLinkRouter methods instead.)
  • Default Diagram.LinkRouter has been changed from QuickRouter to CompositeRouter instance.
  • The bool SmartPolylineEnds property of RoutingOptions has been replaced by PolylineRouting enum property, which also provides an option to prevent inclined link segments for LinkShape.Polyline routes.
  • CreateGdiPen method of Pen class now requires the target Graphics object as an argument.
