New in MindFusion.Diagramming for WPF 3.0.5 (Jun 5, 2014)

  • Export Visio 2013 files:
  • The Visio2013Exporter class can export the content of Diagram and DiagramDocument objects to Visio 2013 VSDX files. In order to use it, add a reference to the MindFusion.Diagramming.Wpf.VisioExport.dll assembly. Similarly to the VDX format exporter, Visio2013Exporter relies on a template file, called Visio2013.vxt, containing some boilerplate Visio XML code. The template must be either located in same folder as the application assemblies, or its path must be specified via the TemplatePath property. At this time the exporter supports shapes from Visio basic stencil. Support for more shapes will be added upon request.
  • Visio2013Importer improvements:
  • The importer now supports Visio group shapes. Child shapes in groups are no longer lost when importing, and their corresponding diagram nodes are attached to the corresponding group node.
  • Visio NURBS curves are now imported as Bezier-style links.
  • Fix for importing connectors with applied rotation transform.
  • Shapes with a ‘hidden’ attribute in master definition are now imported as invisible items.
  • The Item argument of ImportItem event handlers is now pre-set to a DiagramItem instance created for the imported Visio shape, letting you avoid parsing some standard data such as Bounds or Text. You can either modify this item's properties, or replace it with a new instance of a different type.
  • Fixed a crash when a shape master does not have a name attribute (this happens with custom stencils)
  • Fixed a crash when theme1.xml is missing from the imported vsdx archive (this happens with files converted from old Visio versions to 2013 format)
  • Fixed a parse exception for some non-English locales.
  • Fixed a bug where one-segment connectors were imported at wrong positions.
  • Miscellanous:
  • the SetSelfLoopShape event is raised when a link becomes a self-loop, giving you a chance to set a custom shape for the link.
  • LinkLabels are now copied by DiagramLink copy constructor and clipboard methods.
  • Fixed LinkLabel positioning along Bezier links.
  • NodeStyleSelector property of VirtualizingDiagram lets you dynamically apply styles based on node's data.
  • Changing Diagram's ZoomFactor now updates zoom control slider automatically.
  • Fix for wrong scale when printing diagrams with MeasureUnit different from WpfPoint.
  • API changes:
  • The SelectionMoved event has been renamed to SelectionModified, and is also raised if nodes are resized when AllowMultipleResize is enabled. Event handlers now receive SelectionEventArgs parameter instead of EventArgs.
  • The SelectionMoving event has been renamed to SelectionModifying, and is also raised if nodes are resized when AllowMultipleResize is enabled. Event handlers now receive SelectionValidationEventArgs parameter instead of ValidationEventArgs.

New in MindFusion.Diagramming for WPF 3.0.4 (Jan 30, 2014)

  • Import Visio 2013 files:
  • The Visio2013Importer class can import .vsdx files, created by version 2013 of Microsoft Visio. In order to use it, you must add a reference to the MindFusion.Diagramming.Wpf.VisioImport.dll assembly. Various overloads of the Import method can be used to import the Visio drawing into a DiagramDocument whose pages correspond to the Visio pages, or into a single Diagram whose content is merged from all imported pages. When merging multiple pages, their positions in the diagram depend on the PagesPerRow value. Visio2013Importer supports Visio's basic flowchart and data flow stencils. For each node shape from the .vsdx file, the importer creates a ShapeNode object whose Shape, Text, Brush and Stroke properties are set to values corresponding to the imported Visio shape. For each connector shape, the importer creates a DiagramLink object whose Origin and Destination are set to the corresponding imported nodes, and whose ControlPoints reflect the geometry of the connector.
  • Zoom control:
  • The ZoomControl class lets user change interactively the current zoom level and scroll position of a Diagram or DiagramView. To set it up, add a ZoomControl to the window, place it anywhere over the target diagram, and set the control's Target property to that diagram or view. Set the ZoomStep and ScrollStep properties to specify the amount added to view's zoom level or scroll position by ZoomControl's buttons. You can customize the control's appearance by setting properties such as Fill, Stroke, CornerRadius and TickPosition.
  • Miscellaneous:
  • Enable the AllowRenamePages property of TabbedDiagramView to let users rename a DiagramPage interactively by clicking its tab.
  • Several new shapes added for better compatibility with Visio 2013 basic stencil: RightTriangle, Decagon, Trapezoid, Star4Pointed, Star5Pointed, Star6Pointed, Star7Pointed, Star16Pointed, Star24Pointed, Star32Pointed, Donut, Plaque.
  • DefaultEncoding and AutoDetectEncoding properties added to PdfExporter.
  • New RoundAndSquare and RoundAndSquare2 handle styles can be set as the HandlesStyle of nodes.
  • SkipEmptyPages property added to PrintOptions.
  • Support for Visual Studio 2013
  • Fixed invisible inplace edit text-box problem under Windows 8 and .NET 4.5.
  • Fixed bug in undo/redo of RotationAngle assignments.

New in MindFusion.Diagramming for WPF 3.0.2 (Aug 19, 2013)

  • Import Visio 2003 XML drawings
  • AttachTo overloads that attach nodes to link segments or control points now allow specifying negative index values. Negative values are interpreted as relative to the last point or segment, regardless of the current number of link segments. For example, -2 denotes the second-to-last point or segment.
  • Improved handling of clip paths in PdfExporter.
  • The swimlane grid can be exported to Visio by setting the ExportLanes property of VisioExporter.
  • The Copy method lets you copy text attributes between objects implementing the ITextAttributes interface, such as diagram items, table cells and tree items.
  • Improved placement of link labels along shorter link segments.
  • The ArrangeLinkLabels method rearranges link labels whose AutoArrange flag is set.

New in MindFusion.Diagramming for WPF 3.0.1 (May 14, 2013)

  • Selection improvements:
  • Set Behavior to SelectOnly to let users select existing items, but not modify them or draw new ones.
  • The SetsDirtyFlag property of the Selection class specifies whether the Dirty flag should be set when selection changes.
  • SelectionStartMoving event raised when the user begins moving multiple selected items.
  • The ToggleSelection modifier key can be used to select or deselect items by clicking, but disables selection via lasso rectangle.
  • Miscellaneous:
  • The AllowAddChildren and AllowRemoveChildren properties of ContainerNode specify whether users are allowed to add or remove child nodes to / from the container.
  • The GetNearestBorderPoint method of DiagramNode can be used to find a point from the node's border closest to a specified point.
  • The ScrollZoneSize property of Diagram can be used to specify the size of the area near the control edges that starts auto-scrolling.
  • The last row in a TableNode will now be rendered clipped if it fits only partially inside the node, whereas in previous versions the row would not be rendered at all.
  • The HandlesStyle of a link can now be set to Invisible to stop rendering its selection handles, but still allow dragging control points.
  • The Tag property of DiagramDocument (inherited from FrameworkElement) is now automatically saved in XML files if it's a simple value, and SerializeTag is raised to let you save complex objects.
  • Fixed bugs:
  • Ruler alignment guides did not set the Dirty flag.
  • Images exported by CreateImage excluded items at negative coordinates.
  • ZTop and ZBottom methods did not work correctly with layers.

New in MindFusion.Diagramming for WPF 2.8.2 (May 24, 2012)

  • Attached nodes can rotate together with their master node if the group's FollowMasterRotation property is set to RotateChildren.
  • The Text of a ShapeNode can be rotated independently from the node by setting the TextRotationAngle property.
  • Fixed a bug where links did not follow the rotation of their target TreeViewNode.
  • The scroll buttons shown in the caption bar of a TableNode can now be used when the table is rotated.
  • Miscellaneous:
  • The SaveToXml method now saves the definition of a custom Shape if a node's Shape has not any Id specified.
  • If NegatedY is set, the vertical Ruler scale displays negated Y coordinates.
  • The Ruler control scales now start from the origin of the diagram's Bounds instead of (0,0).
  • Fixed a bug where GroupAnchorStyles attachments did not preserve the correct distance for some values.
  • The TextBox control used for in-place editing now wraps text to multiple lines by default.
  • The Diagram control can be automatically added to the Visual Studio toolbox by the installer.

New in MindFusion.Diagramming for WPF 2.5.2 (May 19, 2011)

  • Dynamic node shapes:
  • Shape instances can be defined using custom code that takes into consideration the current width and height of nodes. This allows creating shapes whose primitive elements change non-uniformly, e.g. by growing only in width or height when a node is resized. There are two ways to create such shapes. The first one is to use the Shape constructor that takes a CreatePathDelegate parameter, which can be implemented using a .NET function. Another Shape constructor takes a string argument that represents a Visio-like shape formula evaluated in run-time. The latter method enables serializing the shape code in external files, which can be reused by different applications and by MindFusion components for other platforms.
  • SpringLayout improvements:
  • ~ Better handling of large nodes and nodes with non-uniform size.
  • ~ The SpringLayout energy model has been changed to one that leads to better symmetry in the arranged graphs. The old model can still be used by setting LayoutMethod to Classic. This is recommended when using rounded links.
  • ~ The Randomize property allows starting the layout process from random node positions.
  • Miscellaneous:
  • ~ Call SetZoomFactor to zoom the diagram with the specified zoom center point.
  • ~ The DrawAdjustmentHandles method can be used when custom-drawing to render adjustment handles with their standard look and feel.
  • ~ Set the StableSort property to get consistent results between different runs of LayeredLayout.
  • ~ If hosted controls implement ICloneable, DiagramNodeAdapter uses the Clone method to copy them instead of serialization through XamlWriter and XamlReader.
