Interface IRasterMakerOp

All Superinterfaces:

Serializable

All Known Implementing Classes:

RasterMakerOp

public interface IRasterMakerOp
extends Serializable

Provides access to members that control the Raster Maker operations.

Remarks

Read the Working with ArcGIS Spatial Analyst objects technical document for general information on implementing Spatial Analyst operations.

Product Availability

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

Method Summary

IGeoDataset	makeConstant(double value, boolean treatAsInteger) Makes a constant raster.
IGeoDataset	makeNormal() Makes a normally distributed raster.
IGeoDataset	makeRandom(Object seed) Makes a randomly distributed raster.

Method Detail

makeConstant

IGeoDataset makeConstant(double value,
                         boolean treatAsInteger)
                         throws IOException,
                                AutomationException

Makes a constant raster.

Remarks

value	constant value to create output raster dataset from.
treatAsInteger	a boolean specifying the data type of the output raster dataset. If TRUE, an integer raster will be created. If FALSE, a floating-point raster will be created

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Parameters:

value - The value (in)

treatAsInteger - The treatAsInteger (in)

Returns:

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

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

makeNormal

IGeoDataset makeNormal()
                       throws IOException,
                              AutomationException

Makes a normally distributed raster.

Remarks

creates a grid with randomly dispersed values of a normal distribution on a cell-by-cell basis within the analysis window.

Arguments

There are no arguments with the NORMAL function. The output is a Raster object of the same extent and cell size as the current analysis environment.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Returns:

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

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

makeRandom

IGeoDataset makeRandom(Object seed)
                       throws IOException,
                              AutomationException

Makes a randomly distributed raster.

Remarks

[seed]

a value to be used to reseed the random number generator. This may be a scalar, integer or floating point number, or an expression resulting in such a number. Rasters are not permitted as input. By default the random number generator is automatically seeded using the current value of the system clock (seconds since January 1, 1970). The range of permissible values for [seed] is from ¾(2**31) + 1 to 2**31, or ¾ 2147483647 to 2147483648.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Parameters:

seed - A Variant (in, optional, pass null if not required)

Returns:

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

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
