Package org.geotools.coverage.processing.operation

List of coverage operations.

          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.
Crop The crop operation is responsible for selecting geographic subarea of the source coverage.
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.
Extrema This operation simply wraps JAI Extrema operations described by ExtremaDescriptor inside a GeoTools operation in order to make it spatial-aware.
FilteredSubsample This operation is simply a wrapper for the JAI FilteredSubsample operation which allows me to arbitrarly scale a rendered image while smoothing it out.
GradientMagnitude Edge detector which computes the magnitude of the image gradient vector in two orthogonal directions.
Histogram * This operation simply wraps JAI Histogram operations described by HistogramDescriptor inside a GeoTools operation in order to make it spatial-aware.
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.
Recolor Operation replacing the colors of a org.geotools.coverage.grid.GridCoverage.
Resample Resample a grid coverage using a different grid geometry.
Rescale Maps the sample values of a coverage from one range to another range.
Scale This operation is simply a wrapper for the JAI scale operation which allows me to arbitrarly scale and translate a rendered image.
SelectSampleDimension Chooses N sample dimensions from a grid coverage and copies their sample data to the destination grid coverage in the order specified.
SubsampleAverage This operation is simply a wrapper for the JAI SubsampleAverage operation which allows me to arbitrarily scale a rendered image while smoothing it out.
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).
 

Package org.geotools.coverage.processing.operation Description

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.
