public class DimensionSwapper
extends ReaderWrapper

Handles swapping the dimension order of an image series. This class is useful for both reassigning ZCT sizes (the input dimension order), and shuffling around the resultant planar order (the output dimension order).

Field Details

core

private List<CoreMetadata> core

Core metadata associated with this dimension swapper.

Constructor Details

DimensionSwapper

public DimensionSwapper()

Constructs a DimensionSwapper around a new image reader.

DimensionSwapper

public DimensionSwapper(IFormatReader r)

Constructs a DimensionSwapper with the given reader.

Method Details

makeDimensionSwapper

public static DimensionSwapper makeDimensionSwapper(IFormatReader r)

Converts the given reader into a DimensionSwapper, wrapping if needed.

swapDimensions

public void swapDimensions(String order)

Sets the input dimension order according to the given string (e.g., "XYZCT"). This string indicates the planar rasterization order from the source, overriding the detected order. It may result in the dimensional axis sizes changing. If the given order is identical to the file's native order, then nothing happens. Note that this method will throw an exception if X and Y do not appear in positions 0 and 1 (although X and Y can be reversed).

setOutputOrder

public void setOutputOrder(String outputOrder)

Sets the output dimension order according to the given string (e.g., "XYZCT"). This string indicates the final planar rasterization order—i.e., the mapping from 1D plane number to 3D (Z, C, T) tuple. Changing it will not affect the Z, C or T sizes but will alter the order in which planes are returned when iterating. This method is useful when your application requires a particular output dimension order; e.g., ImageJ virtual stacks must be in XYCZT order.

getInputOrder

public String getInputOrder()

getSizeX

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

• 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.
