The MindFusion Forums - Diagramming for Windows Forms, V6.8
Summary
It contains the following new features and improvements:Set the EnableSpatialIndex property of Diagram to create an index of item positions for faster hit-testing and viewport clipping queries. Rendering a lot of items at small zoom levels or in overviews fit-all mode will still need a lot of processing, so you might want to apply constraints on minimal zoom level of diagram view and overview controls for large diagrams.New PatternRouter class routes links by applying patterns of segment and turn sequences and accepting them when resulting paths do not cross nodes. Custom patterns can be defined as sequence of RouteStep objects specifying whether the path advances by relative or absolute distance, or changes direction: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. This applies the several standard pattern paths when possible, and otherwise routes links using the cost minimizing heuristics-based grid router.Fix for cosmetic / zero-width pens no longer working after KB5006670 Windows Update. Before KB5006670 GDI+ used to apply them as 1-pixel wide lines regardless of graphics unit and zoom level, which the diagram control now implements internally.Installer for the latest version can be downloaded here, or from the clients area on our site:Updated assemblies are also available as MindFusion.Diagramming NuGet package.Enjoy!
