Gets or sets the unit of measure used for logical coordinates in this diagram.

Namespace: MindFusion.Diagramming
Assembly: MindFusion.Diagramming

 Syntax

C#

public GraphicsUnit MeasureUnit { get; set; }

Visual Basic

Public Property MeasureUnit As GraphicsUnit

 Property Value

An instance of the GraphicsUnit class. The default value is Millimeter.

 Remarks

Many properties in the MindFusion.Diagramming API are used to specify the dimensions of diagram items or the size of various visual elements, for example, selection handles, arrowhead shapes, frame widths, and so on. MeasureUnit specifies the measure of length in which these size values are defined.

Changing the measure unit does not automatically rescale the size-related property values. Your application must set appropriate values to: Bounds, GridSizeX, GridSizeY, GridOffsetX, GridOffsetY, AdjustmentHandlesSize, LinkBaseShapeSize, LinkHeadShapeSize, LinkIntermediateShapeSize, TableCaptionHeight, TableColumnWidth, TableRowHeight, CrossingRadius and to the size-related members of RoutingOptions.

Changing the measure unit resets RoutingOptions to default values for the new unit, because performance might suffer greatly if the routing algorithm uses too big or too small GridSize.

The arguments passed to some methods depend on the measure unit too, for example, CreateShapeNode, CreateTableNode, GetNodeAt, GetLinkAt, ZoomToRect.
