Constructor Summary

RasterTreeBuilder(RasterIOOptions options, ICRS dstSRS, File dstDir, int maxTileSize, InterpolationType interpolation)
Creates a new RasterTreeBuilder.

Method Summary

void	buildRasterTree(AbstractRaster srcRaster, int numOfLevels) Builds a raster tree for the input files-
InterpolationType	getInterpolation()
RasterIOOptions	getIOOptions()
int	getTileSize()
void	setBackgroundValue(byte[] backgroundValue) Sets the background value.
void	setBaseEnvelope(Envelope env) Set the envelope of the first level.
void	setBaseResolution(float baseResolution) Set the target resolution of the the first level.
void	setForceTileSize(boolean force) Set if the maxTileSize should be forced to be the actual size.
void	setNumThreads(int num)
void	setOutputFormat(String outputFormat) Sets the format for the output raster files.
void	setOverwriteExistingFiles(boolean overwrite) Set if existing tiles should be replaced (default is true).

Constructor Detail

RasterTreeBuilder

public RasterTreeBuilder(RasterIOOptions options,
                         ICRS dstSRS,
                         File dstDir,
                         int maxTileSize,

Creates a new RasterTreeBuilder. See the additional set*()-methods for further options.

Parameters:

options - needed for reading the raster files

dstSRS - the target crs

dstDir - the output directory of the raster tree

maxTileSize - the max tile size

interpolation - the raster interpolation

Parameters:

env -

setBaseResolution

public void setBaseResolution(float baseResolution)

Set the target resolution of the the first level.

Parameters:

baseResolution - resolution in units/px

setForceTileSize

public void setForceTileSize(boolean force)
