AutomationException
 If the ArcObject component throws an exception.public void setAnnulus(double innerRadius, double outerRadius, int unitsType) throws IOException, AutomationException
innerRadius 
specifies the radius of the inner circle of the annulus from the center of the processing cell. 
outerRadius 
specifies the radius of the outer circle of the annulus neighborhood from the center of the processing cell. The outer circle defines the extent of the neighboorhood. 
unitsType 
An esriGeoAnalysisUnitsEnum defining the type of units to calculate the neighborhood. 
The annulus shape comprises one smaller circle within a larger circle (a donut shape). Cells that fall outside the radius of the smaller circle but inside the radius of the larger circle will be included in the processing of the neighborhood.

radius 
Specifies the radius from the center of the processing cell that the circle neighborhood will span. 
unitsType 
An esriGeoAnalysisUnitsEnum defining the type of units to calculate the neighborhood.

The size of the circle depends on the specified radius. The radius is identified in cells or map units, measured perpendicular to the x or yaxis. Any cell center encompassed by the circle will be included in the processing of the neighborhood.

height 
the number of cells in the ydirection of the neighborhood 
width 
the number of cells in the xdirection of the neighborhood 
entryValues 
an array that defines the irregular shaped neighborhood by using 0 and 1 values to designate cell to include in the neighborhood. A value of "0" for a cell position indicates that the cell is not a member of the neighborhood; a value of "1" for a cell position indicates that its corresponding cell (and value) is a member of the neighborhood and will be used in the neighborhood calculation. An example of a [3 x 5] irregular shaped neighborhood may look like the following.

For specifying an irregularly shaped neighborhood around the processing cell. The kernel specifies which cell positions should be included within the neighborhood. The values in the kernel should be either '0' or '1' (any value not equal to '0' will be interpreted as '1'). A value of '0' for a cell position indicates that the cell is not a member of the neighborhood; a value of '1' for a cell position indicates that its corresponding cell (and value) is a member of the neighborhood. Only cells that are identified as a member will be included in the neighborhood calculations.

width 
the number of units in the xdirection that the neighborhood will encompass. 
height 
the number of units in the ydirection that the neighborhood will encompass. 
unitsType 
An esriGeoAnalysisUnitsEnum defining the type
of units to calculate the neighborhood. esriUnitsMap  neghbourhood is identified by map units (i.e., meters, feet) 
Defines the shape of a neighborhood and to be a rectangle. The x,y position for the processing cell within the neighborhood, with respect to the upperleft corner of the neighborhood, is determined by the following equations:
x = (width of the neighborhood + 1)/2
y = (height of the neighborhood + 1)/2
If the input number of cells is even, the x and ycoordinates are computed using truncation.
For example, in a 5x5 cell neighborhood the x and yvalues are 3, 3. In a 4x4 neighborhood the x and yvalues are 2, 2.

radius 
the radius distance value for the wedge neighborhood. The radius is identified in cells measured perpendicular to the x or yaxis. 
startAngle 
the value of the angle to calculate the start of the wedge neigborhood. 
endAngle 
the value of the angle to calculate the end of the wedge neigborhood. 
unitsType 
An esriGeoAnalysisUnitsEnum defining the type
of units to calculate the neighborhood.

A wedgeshaped neighborhood. The wedge is specified by the start angle, an end angle, and a radius. The wedge extends the radius distance counterclockwise from the starting angle to the ending angle. Angles are specified in degrees, with 0 or 360 representing East. Negative angles may be used.

height 
The number of cells in the xdirection of the neighborhood. 
width 
The number of cells in the ydirection of the neighborhood. 
entryValues 
An array that defines the neighborhood and respective weight values. The value of each cell position in the neighborhood is multiplied by the corresponding weight value and the products are used in the neighborhood calculation. A "0" value is treated like any other value in the kernel. example: a weighted neighborhood array may look like the following. 3 0 0 0 4 
Allows for defining an irregular neighborhood and for specifying which weights will be used to multiply the cell values on an input raster. The x,y position for the processing cell within the neighborhood, with respect to the upperleft corner of the neighborhood, is determined by the following equations:
x = (width + 1)/2
y = (height + 1)/2
If the input number of cells is even, the x and ycoordinates are computed using truncation.
