Method Summary

IGeometry	getGeometry(int hDC, ITransformation displayTransform, IGeometry drawGeometry) Gets the actual geometry of the boundary of the object (which may or may not be a polygon).
void	queryEnvelope(int hDC, ITransformation displayTransform, IGeometry drawGeometry, IEnvelope envelope) Queries the envelope of the boundary of the object.

Method Detail

getGeometry

IGeometry getGeometry(int hDC,
                      ITransformation displayTransform,
                      IGeometry drawGeometry)
                      throws IOException,
                             AutomationException

Gets the actual geometry of the boundary of the object (which may or may not be a polygon).

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Parameters:

hDC - The hDC (A COM typedef) (in)

displayTransform - A reference to a com.esri.arcgis.geometry.ITransformation (in)

drawGeometry - A reference to a com.esri.arcgis.geometry.IGeometry (in)

Returns:

A reference to a com.esri.arcgis.geometry.IGeometry

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

queryEnvelope

void queryEnvelope(int hDC,
                   ITransformation displayTransform,
                   IGeometry drawGeometry,
                   IEnvelope envelope)
                   throws IOException,
                          AutomationException

Queries the envelope of the boundary of the object.

Description

You must instantiate the Envelope before calling QueryEnvelope. For example,

Dim pEnv as IEnvelope

Set pEnv = New Envelope
