Constructor Details

LocalSlices

public LocalSlices(int z,
 int windowSize,
 Voxels<UnsignedByteBuffer> voxels)

Create with focus around a particular slice.

Parameters:

z - index of the slice in the z-dimension.

windowSize - how big the windows is across the z-dimension for storing slices.

voxels - the voxels whose z-dimension is traversed for slices.

Method Details

getLocal

public Optional<UnsignedByteBuffer> getLocal(int relativeZIndex)

Description copied from interface: BufferRetriever

Get a buffer at a particular index in the z-dimension.

The index is relative to a current position e.g. -1, -2, +1, +2 etc.

If an invalid index is requested, then Optional.empty() is returned.

Specified by:

getLocal in interface BufferRetriever

Parameters:

relativeZIndex - the shift in the z index relative to the current z-slice's index

Returns:

the buffer corresponding to the z-index, if it exists.
