Package qupath.lib.regions

Class ImagePlane

java.lang.Object

qupath.lib.regions.ImagePlane

All Implemented Interfaces:

Comparable<ImagePlane>

public class ImagePlane
extends Object
implements Comparable<ImagePlane>

Helper class to store z-slice and time point indices, optionally along with a channel index as well.

These values are frequently required together, such as with ROIs and RegionRequests. It is more convenient (and less error-prone) to use a single ImagePlane instance rather than passing the indices as separate integers each time they are needed.

Method Summary

static ImagePlane	getDefaultPlane()	Returns an ImagePlane with channel -1, z of 0 and t of 0.
static ImagePlane	getPlane(int z, int t)	Returns an ImagePlus, where the z-slice and time point can be specified and channel is ignored (i.e.
static ImagePlane	getPlane(ImageRegion region)	Returns an ImagePlane with channel -1 and z and t set from an existing ImageRegion.
static ImagePlane	getPlane(ROI roi)	Returns an ImagePlane with channel -1, and z and t set from an existing ROI.

getPlane

public static ImagePlane getPlane(int z,
 int t)

Returns an ImagePlus, where the z-slice and time point can be specified and channel is ignored (i.e. set to -1).

Parameters:

Returns:

getDefaultPlane

public static ImagePlane getDefaultPlane()

Returns an ImagePlane with channel -1, z of 0 and t of 0.

Use of this method is discouraged; it is appropriate only for 2D images.

Returns:

getPlaneWithChannel

public static ImagePlane getPlaneWithChannel(ROI roi)

Returns an ImagePlane with channel, z and t set from an existing ROI.

Parameters:

Returns:

getPlane

public static ImagePlane getPlane(ROI roi)

Returns an ImagePlane with channel -1, and z and t set from an existing ROI.

Parameters:

roi -

Returns:

getPlane

public static ImagePlane getPlane(ImageRegion region)

Returns an ImagePlane with channel -1 and z and t set from an existing ImageRegion.

Parameters:

region -

Returns:

getPlaneWithChannel

public static ImagePlane getPlaneWithChannel(int c,
 int z,
 int t)

Returns an ImagePlane, where the channel, z-slice and time point can be specified.

Parameters:

c -

z -

t -

Returns:
