For efficiency UpdatePoint does not check if the spatial reference of the input point is equal to the spatial reference of the PointCollection. Please make sure that the spatial reference of the input point is equal to the spatial reference of the PointCollection before you pass the point in.

Note : You can also explicitly check the spatial reference by using IClone::IsEqual

Example:

//To check spatial reference efficiently
IPoint pointIn = null;
IPointCollection ptColl = null;
ISpatialReference pSpatialReferenceOfCollection = null;

//The next line will not do anything if the two projections are equal
pointIn.project(pSpatialReferenceOfCollection);
ptColl.updatePoint( 1, pointIn);

public void queryEnvelope(IEnvelope outEnvelope)
                   throws IOException,
                          AutomationException
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.

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.

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.

project5

public void project5(ISpatialReference newSpatialReference,

              throws IOException,
                     AutomationException
Same as Project, but with additional parameter projectionHint.

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.

                 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.

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
- …

                     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.

buffer

public IGeometry buffer(double distance)
                 throws IOException,
                        AutomationException
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.

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
