Description

SetEmpty returns the Geometry to its original initialization state by releasing all data referenced by the Geometry.

Remarks


Use the SetEmpty method to clear geometries and release memory. For example, a polygon with 100 rings will have an internal array of 100 pointers to ring objects. That array will go away and Release will be called on each ring. If that polygon had the only reference on those rings, then they'll go away, which releases all their segments, which may also then go away.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Windows, Solaris, Linux

Specified by:
setEmpty in interface IGeometry
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

Copies this geometry's envelope properties into the specified envelope.

Description

Returns the unique Envelope that binds the Geometry object. This is the smallest Envelope that Contains the object.

Remarks

Note: The output geometry must be co-created prior to the query. The output geometry is not co-created by the method; it is populated. This can be used in performance critical situations. For example, creating the geometry only once outside a loop and use the query method could improve performance.

QueryEnvelope Example

project

public void project(ISpatialReference newReferenceSystem)
             throws IOException,
                    AutomationException
Projects this geometry into a new spatial reference.

Description

To Project, the geometry needs to have a Spatial Reference set, and not have an UnknownCoordinateSystem. The new spatial reference system passed to the method defines the output coordinate system. If either spatial reference is Unknown, the coordinates are not changed. The Z and measure values are not changed by the Project method.

A geometry is not densified before it is projected. This can lead to the output geometries not reflecting the 'true' shape in the new coordinate system. A straight line in one coordinate system is not necessarily a straight line in a different coordinate system. Use IGeometry2::ProjectEx if you want to densify the geometries while they are projected.

The Project method must be applied on high-level geometries only. High-Level geometries are point, multipoint, polyline and polygon. To use this method with low-level geometries such as segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), paths or rings, they must be wrapped into high-level geometry types.

If a geometry is projected to a projected coordinate system that can't represent the geographic area where the geometry is located (or if trying to move an xy coordinate from outside the projected coordinate system back into geographic), the geometry will be set to empty.

Remarks

Note: This method can only be called upon the top level geometries (Points, Multipoints, Polylines and Polygons). If the from/to spatial references have different geographic coordinate systems, the Project method looks for a GeoTransformationsOperationSet. If the set of Geotransformations is present in memory, Project will use it to perform a geographic/datum Transformation. To use a specific geotransformation, use the IGeometry2::ProjectEx method.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
project in interface IGeometry
Parameters:
newReferenceSystem - A reference to a com.esri.arcgis.geometry.ISpatialReference (in)
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

snapToSpatialReference

public void snapToSpatialReference()
                            throws IOException,
                                   AutomationException
Moves points of this geometry so that they can be represented in the precision of the geometry's associated spatial reference system.

Remarks

SnapToSpatialReference rounds all coordinates to the resolution defined by the geometry's spatial reference system. This has a similar effect on the geometry as storing the geometry in a Geodatabase.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
snapToSpatialReference in interface IGeometry
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

geoNormalize

public void geoNormalize()
                  throws IOException,
                         AutomationException
Shifts longitudes, if need be, into a continuous range of 360 degrees.

Remarks

GeoNormalize acts on geometries whose geographic system coordinates are below -180 degrees longitude or over +180 degrees longitude or on geometries that span the +-180 degrees longitude.
This method requires the geometry to have a valid spatial reference (geographic or projected coordinate system).
This method is used internally as part of the projection process for polygons and polylines. It is typically not used by itself.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
geoNormalize in interface IGeometry
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

geoNormalizeFromLongitude

public void geoNormalizeFromLongitude(double longitude)
                               throws IOException,
                                      AutomationException
Normalizes longitudes into a continuous range containing the longitude. This method is obsolete.

Remarks

This method is obsolete. Use IGeometry::GeoNormalize instead.
This method requires the geometry to have a valid spatial reference (geographic or projected coordinate system).

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
geoNormalizeFromLongitude in interface IGeometry
Parameters:

                      boolean bAngularDensify,
                      double maxSegmentLength,
                      double maxDeviation)
               throws IOException,
                      AutomationException
Projects a geometry, optionally applies a GeoTransformation, and optionally densifies the geometry.

Remarks

By default, ProjectEx will not densify geometries as they are projected. This can lead to the output geometries not reflecting the 'true' shape in the new coordinate system. A straight line in one coordinate system is not necessarily a straight line in a different coordinate system. Set the bAngularDensify parameter if you want to densify the geometries while they are projected.

Description

To Project, the geometry needs to have a Spatial Reference set, and not have an UnknownCoordinateSystem. The new spatial reference system passed to the method defines the output coordinate system. If either spatial reference is Unknown, the coordinates are not changed. The Z and measure values are not changed by the Project method.

A geometry is not densified before it is projected. This can lead to the output geometries not reflecting the 'true' shape in the new coordinate system. A straight line in one coordinate system is not necessarily a straight line in a different coordinate system. Use IGeometry2::ProjectEx if you want to densify the geometries while they are projected.

The projectionHint parameter contains information about whether a geometry will cross the coordinate system horizons. If it doesn't, parts of the code that check this and intersect the geometry with the horizons can be omitted. This can dramatically improve performance. Use ISpatialReference3::ProjectionHint to initialize this parameter.

If it doesn't, parts of the code that check this and intersect the geometry with the horizons can be omitted. This can dramatically improve performance. Use ISpatialReference3::ProjectionHint to initialize this parameter.

Remarks

By default, ProjectEx will not densify geometries as they are projected. This can lead to the output geometries not reflecting the 'true' shape in the new coordinate system. A straight line in one coordinate system is not necessarily a straight line in a different coordinate system. Set the bAngularDensify parameter if you want to densify the geometries while they are projected.

                 throws IOException,
                        AutomationException
Indicates if the defined relationship exists.

Description

Relation allows a general relation defined using the Shape Comparison Language to be determined between two input geometries. The Shape Comparison Language is based on the Calculus-Based Method (CBM), as described and defined by Clementini and Felice, but has some extensions specific to working with vertex-based geometries and is fully described in the Technical Documents section of the ArcObjects Developer Help. Please refer to the Shape Comparison Language documentation for proper syntax and available functionality.

Note that at the current release, Relation only operates with straight lines.

isSimple

public boolean isSimple()
                 throws IOException,
                        AutomationException
Indicates whether this geometry is known (or assumed) to be topologically correct, after explicitly determining this if the geometry is not already known (or assumed) to be simple.

Description

Returns TRUE if the geometry is topologically Simple (refer to the discussion for the Simplify method). If the geometry is not Simple, it may be necessary to call Simplify to enforce topological consistency. Editing a geometry can change the IsSimple state of the geometry.

Remarks

ITopologicalOperator methods must be applied on high-level geometries only. High-Level geometries are point, multipoint, polyline and polygon. To use this method with low-level geometries such as segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), paths or rings, they must be wrapped into high-level geometries types.

The xy cluster tolerance value of the geometry's associated spatial reference is used by this method. If the goal of this method is to determine if a geometry can be persisted in an sde (or other integer-based) layer without alteration, you may wish to use the minimum xy cluster tolerance value (ISpatialReferenceTolerance::SetMinimumXYTolerance) before applying this method (don't forget to set it back).

This method does not support GeometryBags.

isKnownSimple

public boolean isKnownSimple()
                      throws IOException,
                             AutomationException
Indicates whether this geometry is known (or assumed) to be topologically correct.

Description

Returns TRUE when the geometry is aware that it is Simple. IsKnownSimple may return FALSE even if the geometry is simple as long as the geometry is not aware of its IsSimple state. Calling either IsSimple or Simplify makes the IsSimple state known to the geometry. Topologically altering the geometry makes the IsKnownSimple state FALSE until the IsSimple state is again checked.

Remarks

Here is the status of the IsKnownSimple flag in some common situations:


IsKnownSimple = 'False'
- A non-empty newly created geometry. For example, creating a polygon using IPointCollection sets the flag IsKnownSimple = 'false' on that geometry.
- Geometry after projection (IGeometry::Project )
- Geometry after generalization (IPolycurve::Generalize ) or smoothing(IPolycurve::Smooth )
- …

IsKnownSimple = 'True'
- A geometry coming directly from a feature class
- An empty geometry
- Output geometry of any method on ITopologicalOperator
- …

This method does not support GeometryBags.

simplify

public void simplify()
              throws IOException,
                     AutomationException
Makes this geometry topologically correct.

Description

Simplify permanently alters the input geometry, making its definition "topologically legal" with respect to its geometry type:


The XY tolerance property of the geometry's associated spatial reference is used during the simplify operation for polylines and polygons.

Remarks

This method first looks at the ITopologicalOperator::IsKnownSimple flag before starting processing. If the flag is 'true' then operation is interrupted and the geometry is considered simple. If the flag is 'false' then the geometry consistency is checked and the geometry is updated as needed.

ITopologicalOperator methods must be applied on high-level geometries only. High-Level geometries are point, multipoint, polyline and polygon. To use this method with low-level geometries such as segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), paths or rings, they must be wrapped into high-level geometries types.

Constructs a polygon that is the locus of points at a distance less than or equal to a specified distance from this geometry.

Remarks


The buffer distance is in the same units as the source shape that is being buffered.

A negative distance can be specified to produce a buffer inside the original polygon. This cannot be used with polyline. ITopologicalOperator methods must be applied on top-level geometries only. Top-Level geometries are point, multipoint, polyline and polygon. To use this method with segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), paths or rings, they must be wrapped with a top-level type.

                            AutomationException
Constructs the convex hull of this geometry.

Description

The ConvexHull of a geometry is the minimal bounding polygon such that all outer angles are convex. The ConvexHull of a point is the point itself.

Remarks

ITopologicalOperator methods must be applied on high-level geometries only. High-Level geometries are point, multipoint, polyline and polygon. To use this method with low-level geometries such as segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), paths or rings, they must be wrapped into high-level geometries types.

                           AutomationException
Constructs the geometry that is the set-theoretic intersection of the input geometries. Use different resultDimension values to generate results of different dimensions.

Description

The Intersection of two Geometries of the same Dimension is a Geometry containing only the regions of overlap between the original geometries.

Remarks

Intersection is basically an AND between input geometries.

ITopologicalOperator methods must be applied on high-level geometries only. High-Level geometries are point, multipoint, polyline and polygon. To use this method with low-level geometries such as segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), paths or rings, they must be wrapped into high-level geometries types.

This method does not support GeometryBags.

Since ArcGIS 9.2, Intersect has a larger cost - it takes longer to run the method. Therefore, it is a better approach to test if the two geometries are disjoint before calling Intersect.

Constructs the geometry that is the set-theoretic union of the input geometries.

Description

The Union of two Geometries of the same Dimension is a single Geometry corresponding to the combination of both Geometries such that anything within either of the original geometries is also part of the unioned geometry, but anything common to both geometries only exists once in the unioned geometry.

Remarks

The Union is basically an OR between the input geometries.

ITopologicalOperator methods must be applied on high-level geometries only. High-Level geometries are point, multipoint, polyline and polygon. To use this method with low-level geometries such as segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), paths or rings, they must be wrapped into high-level geometries types.

Remarks

ITopologicalOperator methods must be applied on high-level geometries only. High-Level geometries are point, multipoint, polyline and polygon. To use this method with low-level geometries such as segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), paths or rings, they must be wrapped into high-level geometries types.

QueryClipped returns the portion of the input Geometry that is Contained by the input Envelope. The returned geometry is the same type as the original geometry.

Remarks

ITopologicalOperator methods must be applied on high-level geometries only. High-Level geometries are point, multipoint, polyline and polygon. To use this method with low-level geometries such as segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), paths or rings, they must be wrapped into high-level geometries types.

The other geometry must be an high-level geometry. High-Level geometries are point, multipoint, polyline and polygon. To use it with low-level geometries such as segments (Line, Circular Arc, Elliptic Arc, Bézier Curve), path or ring they must be wrapped into high-level geometries type. The output geometry must be co-created prior to the query. The output geometry is not co-created by the method; it is populated. This can be used in performance critical situations. For example, creating the geometry only once outside a loop and use the query method could improve performance.

This method does not support GeometryBags.

                 throws IOException,
                        AutomationException
Adds a reference to the input geometry either at the end, or before, or after the specified index.

Remarks

When applying the AddGeometry method give either the before or after index and not both. Adding a Geometry to the collection as the first one is done by setting the before index as 0.

The spatial reference of the GeometryCollection is transferred (objects projected if necessary) to any objects added to it. However the spatial reference of the added geometry is not transferred to the GeometryCollection. Always make sure to set the spatial reference on the object GeometryCollection prior to add other geometries to it to avoid creating invalid geometry. For example, adding geometry objects to a GeometryBag that doesn't have a well-defined spatial reference will set an undefined spatial reference to all the objects added to the bag. Using this GeometryBag may cause unexpected behavior with the ITopologicalOperator::ConstructUnion method.

scale

public void scale(IPoint origin,
                  double sx,
                  double sy)
           throws IOException,
                  AutomationException
Scales about the specified origin using seperate horizonal and vertical scales. The origin point can be in a different spatial reference than the geometry being scaled.

Description

Stretches the Geometry a factor of sX along the X-Axis and a factor of sY along the Y-Axis (where sX is the ratio of Old Width to New Width, and sY is the ratio of Old Height to New Height). The Origin point is the reference Point from which the transformation is performed (Regardless of the location of the Origin point, the Geometry resulting from the transformation is the same, except for a positional offset). The Origin is the only point in the transformation guaranted to remain in the same location after the transformation is complete.

Remarks

Note: Caution must be taken when scaling a CircularArc or a geometry containing CircularArc segments. Unless Abs(ScaleX) = Abs(ScaleY), the resulting CircularArcs will not retain the characteristics of the original geometry (since they remain CircularArcs).

Scale Example

            throws IOException,
                   AutomationException
Rotates about the specified origin point. The angle is in radians. The origin can be in a different spatial reference than the geometry being rotated.

Description

Rotate performs an angular transform (rotation) on the Geometry. The Origin is the only point in the transformation guaranteed to remain in the same location after the transformation is performed. Regardless of the Origin, the transformed Geometry is the same, except for a positional offset. The RotationAngle is measured in radians.

Remarks

An Envelope cannot be Rotated.
