        Note that if the input reader does not support the requested conversion, the output data format will be the same as the input data format (no conversion).

      • isCrcCheckDone

        public boolean isCrcCheckDone()

      • setOutputDataFormat

        public boolean setOutputDataFormat​(SoDataSet.DataTypes dataType)
        Set the output data format with an SoDataSet.DataType.

      • setLowResAlgorithm

        public boolean setLowResAlgorithm​(int lowResAlgorithm)
        Set the algorithm used to build low resolution tiles.
        Available options are :
        • 0: To use decimation algorithm

      • setOutputHeaderOnly

        public void setOutputHeaderOnly​(boolean headerOnly)
        Set the header only feature.

      • setCrcCheck

        public void setCrcCheck​(boolean addCrcCheck)
        Set CRC32 check on compression.
        Like -C command line argument. When compression is enabled using -c, adds a data integrity check value to all compressed tiles. If the environment variable LDM_COMPRESS_CHECK_CRC32 is set, data values will be checked each time they are read from disk. Default is false.

      • setCompressionName

        public boolean setCompressionName​(java.lang.String compressionName)
        Set compression name.
        Like the -c command line argument. See also setCompressionLevel(). The following compression types are currently supported:.
        • gzip:
          This is a lossless compression and can be used on any type of data. See SoGzipDataCompressor.
        • jpeg:
          This is a lossy compression. See SoJpegDataCompressor.
          Limitation: Can only be used on 8-bit scalar data sets.
        • jp3d:
          This is a wavelet compression that can be lossless or lossy. See SoJp3dDataCompressor.
          Limitation: 32 bit data values (float or integer) are always converted to 16 bit values.

        Returns true if parameter is valid, else returns false.

      • setCompressionLevel

        public void setCompressionLevel​(int compressionLevel)
        Set compression level.
        Like the -l command line argument. See also setCompressionName(). The meaning of this parameter depends on the type of compression used:
        • gzip
          Level must be between 0 and 9: 0 gives no compression, 9 gives best compression but slower speed. Default is 3.
        • jpeg:
          Level must be between 0 and 100: 0 gives best compression but most loss of data, 100 gives minimum compression and minimum data alteration. Default is 85.
        • jp3d:
          A level of 0 specifies the lossless mode, and any other value sets the target PSNR (Peak Signal to Noise Ratio). Typical values for PSNR are: 70dB for near lossless mode, and 40dB for visually lossless mode.

      • setInputRangeMinMax

        public boolean setInputRangeMinMax​(double min,
                                   double max)
        Set the input data range to map to the output data format.
        Like the -r command line argument. If not specified, and input type is float and output type is integer, the values are simply cast into the output data type. Returns true if parameter is valid, else returns false.

      • setTargetWordFormat

        public boolean setTargetWordFormat​(int wordFormat)
        Set the target machine word format.
        Like the -w command line argument. Default is the current machine word format. wordFormat parameter is 0 for Big Endian, and 1 for Little Endian. Returns true if parameter is valid, else returns false.

        public SoDataSet.DataTypes getOutputDataFormat()
        Returns the output data format.

      • getCompressionName

        public java.lang.String getCompressionName()

        Set RGBA data mode (output will be unsigned int32 RGBA values).

      • getDataFileName

        public java.lang.String getDataFileName()
        Returns the complete data filename (i.e. : the whole path to .dat file).

      • isInputDataRangeSpecified

      • isRGBAMode

        public boolean isRGBAMode()
        Returns true if RGBA mode.

      • setDataFileName

        public void setDataFileName​(java.lang.String dataFileName)
        Set data filename (i.e. the .dat filename).
        Like the -O command line argument. Default is the same as the header file, with .dat extension.

      • isHistogramEnabled

        public boolean isHistogramEnabled()
        Returns true if histogram will be computed.

      • getDataSectionFileName

        public java.lang.String getDataSectionFileName()

      • enableHistogram

        public void enableHistogram​(boolean flag)
        Specify if the histogram must be computed or not. Default is true.

        Disabling Histogram generation will greatly speedup the conversion process, but some VolumeViz rendering features and optimizations won't be available.

        It also implies that the following information won't be computed:

        • dataset min and max values
        • per Tile min max values

        Note also that if RGBA mode is set then no histogram is computed.

        Set the undefined value.
        Like the -u command line argument. The given value will be stored in the LDM file. Default is NaN (Not a Number). This is currently used by SoHeightFieldRender (vertices with undefined values are not rendered).
