Description
Class Summary | |
---|---|
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] ... ... |
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. |
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] ... ... |
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. |
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 |
ZonalStats | This operation simply wraps Jai-tools Zonalstats operations described by
ZonalStatsDescriptor inside a GeoTools operation in order to make it
spatial-aware. |
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.
