ArcObjects Library Reference (Schematic)  

ISchematicAlgoCompression Interface

Provides access to members that control the Compression schematic algorithm.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires Schematics Extension.


The Compression algorithm compresses the schematic features contained in a schematic diagram toward the middle of the diagram while trying to maintain relative positioning. It gives interesting results on networks that span thousands of miles and are difficult to view and understand in their true geographic positions (for example, in the transmission utilities industry).


Read/write property AbsoluteParameters Indicates if the values set for the spacings must be interpreted as absolute units.
Read-only property AlgorithmCLSID The CLSID of the algorithm.
Read/write property Available Indicates if the algorithm is currently available.
Read/write property ClusterThresholdDistance Threshold distance used to cluster connected nodes together.
Read/write property CompressTowardCenter Indicates if the algorithm moves the nodes toward the diagram center.
Read/write property DistanceBetweenClusters Minimum distance to preserve between connected clusters.
Read-only property Enabled Indicates if the algorithm is currently enabled.
Method Execute Execute the schematic algorithm.
Read/write property HeedContainers Indicates if containers and their contents are processed as a whole or independently.
Read/write property KeepInsideVertices Indicates if link vertices inside containers are kept or removed.
Read/write property KeepOutsideVertices Indicates if the first link vertex outside a container is kept or removed.
Read/write property Label The label of the algorithm.
Read/write property Overridable Indicates if the algorithm properties page is editable from ArcMap; that is, enabling the Layout Properties button in ArcMap.
Read/write property PropertySet The property set of the algorithm contains a collection of its parameters and their values.
Read/write property SchematicDiagramClassName The diagram class object used to initialize the algorithm.
Read-only property UseEndNode Indicates if the algorithm use end nodes.
Read-only property UseRootNode Indicates if the algorithm use root nodes.
