Description
Class Summary  
Absolute  Computes the mathematical absolute value of each sample value. 
AddConst  Adds constants (one for each band) to every sample values of the source coverage. 
Convolve  Computes each output sample by multiplying elements of a kernel with the samples surrounding a particular source sample. 
DivideByConst  Divides every sample values of the source coverage by constants (one for each band). 
Exp  Takes the exponential of the sample values of a coverage. 
GradientMagnitude  Edge detector which computes the magnitude of the image gradient vector in two orthogonal directions. 
Interpolate  Specifies the interpolation type to be used to interpolate values for points which fall between grid cells. 
Invert  Inverts the sample values of a coverage. 
Log  Takes the natural logarithm of the sample values of a coverage. 
MaxFilter  For each position of the mask, replaces the center pixel by the maximum of the pixel values covered by the mask. 
MedianFilter  For each position of the mask, replaces the center pixel by the median of the pixel values covered by the mask. 
MinFilter  For each position of the mask, replaces the center pixel by the minimum of the pixel values covered by the mask. 
MultiplyConst  Multiplies every sample values of the source coverage by constants (one for each band). 
NodataFilter  Replaces NaN values by the weighted average of neighbors values. 
Resample  Resample a grid coverage using a different grid geometry. 
Rescale  Maps the sample values of a coverage from one range to another range. 
SelectSampleDimension  Chooses N sample dimensions from a grid coverage and copies their sample data to the destination grid coverage in the order specified. 
SubtractConst  Subtracts constants (one for each band) from every sample values of the source coverage. 
SubtractFromConst  Subtracts every sample values of the source coverage from constants (one for each band). 
List of coverage operations. This package is useful for documentation purpose since class names match exactly operation names, and the javadoc for each class provides a table of valid arguments. But the classes provided there should not be used directly. There is no need to instantiate them, since it is already done by the processor which manage them.
