    Description copied from interface: IFormatReader

    - 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

  - 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., SDTReader handles spectral-lifetime data with interleaved lifetime bins and non-interleaved spectral channels.

```
public java.lang.Class<?> getNativeDataType()
```
    Description copied from interface: IFormatHandler
    
    Returns the native data type of image planes for this reader, as returned by IFormatReader.openPlane(int, int, int, int, int) or IFormatWriter.savePlane(int, java.lang.Object). For most readers this type will be a byte array; however, some readers call external APIs that work with other types such as BufferedImage.
    
    Specified by:
    
    getNativeDataType in interface IFormatHandler
  - setId
```
public void setId(java.lang.String id)
           throws FormatException,
                  java.io.IOException
```
    Description copied from interface: IFormatHandler
