Interface IRPCXform

All Superinterfaces:

IGeodataXform, Serializable

All Known Implementing Classes:

RPCXform

public interface IRPCXform
extends IGeodataXform, Serializable

Provides access to members that control a RPC transform.

Remarks

The IRPCXform interface is used to create a RPCXform object.

The PPC parameters only define a reverse transformation. To create a RPCXform object to work with raster data, the forward transformation must also be set.

Product Availability

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

Method Summary

void	defineFromCoefficients(Object pRPC) Defines a RPC transform from 90 coefficients.
Object	getCoefficients() Gets the rational polynomial coefficients.
IGeodataXform	getForwardXform() The forward transformation from native to GCS WGS84.
void	putCoefficients(double[] rPC) Puts the rational polynomial coefficients.
void	queryCoefficients(double[] rPC) Queries the rational polynomial coefficients.
void	setForwardXformByRef(IGeodataXform ppXf) The forward transformation from native to GCS WGS84.

Method Detail

getForwardXform

IGeodataXform getForwardXform()
                              throws IOException,
                                     AutomationException

The forward transformation from native to GCS WGS84.

Product Availability

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

Returns:

A reference to a com.esri.arcgis.geodatabase.IGeodataXform

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

setForwardXformByRef

void setForwardXformByRef(IGeodataXform ppXf)
                          throws IOException,
                                 AutomationException

The forward transformation from native to GCS WGS84.

Remarks

Set farward transformation for the RPCXform.

Product Availability

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

Parameters:

ppXf - A reference to a com.esri.arcgis.geodatabase.IGeodataXform (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

defineFromCoefficients

void defineFromCoefficients(Object pRPC)
                            throws IOException,
                                   AutomationException

Defines a RPC transform from 90 coefficients.

Description

The argument is a variant type with 92 RPC parameters. This method is easy to use in VB. For C++ type of programming, use PutCoefficients method.

Product Availability

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

Parameters:

pRPC - A Variant (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getCoefficients

Object getCoefficients()
                       throws IOException,
                              AutomationException

Gets the rational polynomial coefficients.

Remarks

The return is a variant type with 92 RPC parameters. This method is for VB users. For C++ type of programming, use QueryCoefficients method.

Product Availability

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

Returns:

A Variant

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

putCoefficients

void putCoefficients(double[] rPC)
                     throws IOException,
                            AutomationException

Puts the rational polynomial coefficients.

Remarks

Set RPC coefficient, used for C++ type of programming.

Product Availability

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

Parameters:

rPC - The rPC (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

queryCoefficients

void queryCoefficients(double[] rPC)
                       throws IOException,
                              AutomationException

Queries the rational polynomial coefficients.

Remarks

Get RPC coefficients (92 parameters), used for C++ type of programming. For VB users, GetCoefficients can be used.

Product Availability

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

Parameters:

rPC - The rPC (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
