  • Constructor Details

    • HCompressorOption

      public HCompressorOption()

  • Method Details

    • copy

      public HCompressorOption copy()
      Specified by:
      copy in interface ICompressOption
      Returns:
      copy the option (normally the option from with the copy happened is saved as original).

    • getCompressionParameters

      public ICompressParameters getCompressionParameters()
      Specified by:
      getCompressionParameters in interface ICompressOption
      Returns:
      the parameters that must be synchronized with the hdu meta data.

    • getScale

      public int getScale()

    • getTileHeight

      public int getTileHeight()

    • getTileWidth

      public int getTileWidth()

    • isLossyCompression

      public boolean isLossyCompression()
      Specified by:
      isLossyCompression in interface ICompressOption
      Returns:
      true if the compression done with this specified options uses approximations. That means if the reconstruction of the data is excact the return should be false.
