    • isFalseColor

      public boolean isFalseColor()
      Description copied from interface: IFormatReader
      Returns false if IFormatReader.isIndexed() is false, or if IFormatReader.isIndexed() is true and the lookup table represents "real" color data. Returns true if IFormatReader.isIndexed() is true and the lookup table is only present to aid in visualization.
      Specified by:
      isFalseColor in interface IFormatReader

    • get8BitLookupTable

      public byte[][] get8BitLookupTable() throws FormatException, IOException
      Description copied from interface: IFormatReader
      Gets the 8-bit color lookup table associated with the most recently opened image. If no image planes have been opened, or if IFormatReader.isIndexed() returns false, then this may return null. Also, if IFormatReader.getPixelType() returns anything other than FormatTools.INT8 or FormatTools.UINT8, this method will return null.
      Specified by:
      get8BitLookupTable in interface IFormatReader
      Throws:

      public short[][] get16BitLookupTable() throws FormatException, IOException
      Description copied from interface: IFormatReader
      Gets the 16-bit color lookup table associated with the most recently opened image. If no image planes have been opened, or if IFormatReader.isIndexed() returns false, then this may return null. Also, if IFormatReader.getPixelType() returns anything other than FormatTools.INT16 or FormatTools.UINT16, this method will return null.
      Specified by:
      get16BitLookupTable in interface IFormatReader

    • getDimensionOrder

      public String getDimensionOrder()
      Description copied from interface: IFormatReader
      Gets a five-character string representing the dimension order in which planes will be returned. Valid orders are:
      • XYCTZ
      • XYCZT
      • XYTCZ
      • XYTZC
      • XYZCT
      • XYZTC
      In cases where the channels are interleaved (e.g., CXYTZ), C will be the first dimension after X and Y (e.g., XYCTZ) and the IFormatReader.isInterleaved() method will return true.
      Specified by:
      getDimensionOrder in interface IFormatReader

    • isOrderCertain

      public boolean isOrderCertain()
      Description copied from interface: IFormatReader

      isOrderCertain in interface IFormatReader

    • isThumbnailSeries

      public boolean isThumbnailSeries()
      Description copied from interface: IFormatReader
      Gets whether the current series is a lower resolution copy of a different series.
      Specified by:
      isThumbnailSeries in interface IFormatReader

    • isInterleaved

      public boolean isInterleaved()
      Description copied from interface: IFormatReader
      Gets whether or not the channels are interleaved. This method exists because X and Y must appear first in the dimension order. For interleaved data, IFormatReader.getDimensionOrder() returns XYCTZ or XYCZT, and this method returns true. Note that this flag returns whether or not the data returned by IFormatReader.openBytes(int) is interleaved. In most cases, this will match the interleaving in the original file, but for some formats (e.g. TIFF) channel re-ordering is done internally and the return value of this method will not match what is in the original file.
      Specified by:
      isInterleaved in interface IFormatReader

    • isInterleaved

      public boolean isInterleaved(int subC)
      Description copied from interface: IFormatReader
      Gets whether or not the given sub-channel is interleaved. This method exists because some data with multiple rasterized sub-dimensions within C have one sub-dimension interleaved, and the other not—e.g.,
      invalid reference 
      loci.formats.in.SDTReader
      handles spectral-lifetime data with interleaved lifetime bins and non-interleaved spectral channels.
      Specified by:
      isInterleaved in interface IFormatReader

      Description copied from interface: IFormatReader
      Obtains the specified image plane (or sub-image thereof) in the reader's native data structure.

      Returns:
      an int indicating that we cannot, must, or might group the files. A return value of FormatTools.MUST_GROUP indicates that the files cannot be handled separately; the reader will always detect and read all files in the dataset. FormatTools.CAN_GROUP indicates that the files may be handled separately, but file grouping must then be disabled via IFormatReader.setGroupFiles(boolean). FormatTools.CANNOT_GROUP indicates that the files must be handled separately; the reader will not attempt to read all files in the dataset (this is rare).
      Throws:
      FormatException
      IOException
