Method Detail

projectEx

public void projectEx(ISpatialReference newReferenceSystem,
                      int direction,
                      IGeoTransformation geoTransformation,
                      boolean bAngularDensify,
                      double maxSegmentLength,
                      double maxDeviation)
               throws java.io.IOException,
                      AutomationException

Projects a geometry, optionally applies a GeoTransformation, and optionally densifies the geometry.

Supported Platforms

Windows, Solaris, Linux

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.

Parameters:

newReferenceSystem - A reference to a com.esri.arcgis.geometry.ISpatialReference (in)

direction - A com.esri.arcgis.geometry.esriTransformDirection constant (in)

geoTransformation - A reference to a com.esri.arcgis.geometry.IGeoTransformation (in)

bAngularDensify - The bAngularDensify (in)

maxSegmentLength - The maxSegmentLength (in)

maxDeviation - The maxDeviation (in)

Throws:

java.io.IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
