Package org.geotools.coverage.processing.operation

package org.geotools.coverage.processing.operation
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.
  • Class
    Description
    Absolute
    Computes the mathematical absolute value of each sample value.
    Add
    Create a new coverage as the sum of two source coverages by doing pixel by pixel addition: result[0][0] = source0[0][0] + source1[0][0] ... ... result[i][j] = source0[i][j] + source1[i][j] ... ... result[n-1][m-1] = source0[n-1][m-1] + source1[n-1][m-1]
    AddConst
    Adds constants (one for each band) to every sample values of the source coverage.
    Affine
    This operation is simply a wrapper for the JAI Affine operation
    BandMerge
    OperationJAI subclass used for executing the "Merge" of multiple coverages into a single coverage with multiple bands.
    BandMerge.TransformList
    Enum used for selecting an Affine Transformation to use for backward mapping the final coverage pixel to the Model Space.
    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.
    GridCoverage2DRIA
    A RenderedImage that provides values coming from a source GridCoverage2D, with a backing grid addressable as the target GridCoverage2D.
    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.
    Mosaic
    This operation does a mosaic of multiple GridCoverage2Ds.
    Mosaic.GridGeometryPolicy
    Enum used for choosing the output GridGeometry2D to use and then resampling all the GridCoverage2D to its resolution.
    Mosaic.Params
    A block of parameters for a GridCoverage2D processed by the Mosaic operation.
    Multiply
    Create a new coverage as the multiplication of two source coverages by doing pixel by pixel multiplication: result[0][0] = source0[0][0] * source1[0][0] ... ... result[i][j] = source0[i][j] * source1[i][j] ... ...
    MultiplyConst
    Multiplies every sample values of the source coverage by constants (one for each band).
    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 arbitrarily 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.
    ShadedRelief
    A simple wrapper for the jai-ext ShadedRelief operation.
    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).
    Warp
    This operation is simply a wrapper for the JAI Warp operation
    ZonalStatistics
    This operation is similar to the ZonalStats operation but implements a new version of the "ZonalStats" operation.
