Class VoxelsResizerImgLib2

Object

VoxelsResizer

VoxelsResizerImgLib2

Direct Known Subclasses:

Lanczos, Linear, NearestNeighbor

public abstract class VoxelsResizerImgLib2
extends VoxelsResizer

Performs resizing of VoxelBuffers using ImgLib2's interpolation.

By default, voxels at the boundaries are mirrored (i.e. voxels just after the boundary are treated like the closest voxel inside the boundary), but this can be changed to an extent strategy instead.

Method Details

resizeByte

public VoxelBuffer<UnsignedByteBuffer> resizeByte(VoxelBuffer<UnsignedByteBuffer> voxelsSource,
 VoxelBuffer<UnsignedByteBuffer> voxelsDestination,
 Extent extentSource,
 Extent extentDestination)

Description copied from class: VoxelsResizer

Interpolates from voxelsSource to voxelsDestination for unsigned 8-bit buffers.

Both buffers must be 2-dimensional, not 3-dimensional.

Specified by:

resizeByte in class VoxelsResizer

Parameters:

voxelsSource - voxels to interpolate from.

voxelsDestination - voxels to write the interpolated values into.

extentSource - extent corresponding to voxelsSource.

extentDestination - extent corresponding to extentDestination.

Returns:

the destination buffer (either as passed, or a new one that was created).

resizeShort

public VoxelBuffer<UnsignedShortBuffer> resizeShort(VoxelBuffer<UnsignedShortBuffer> voxelsSource,
 VoxelBuffer<UnsignedShortBuffer> voxelsDestination,
 Extent extentSource,
 Extent extentDestination)

Description copied from class: VoxelsResizer

Interpolates from voxelsSource to voxelsDestination for unsigned 16-bit buffers.

Both buffers must be 2-dimensional, not 3-dimensional.

Specified by:

resizeShort in class VoxelsResizer

Parameters:

voxelsSource - voxels to interpolate from.

voxelsDestination - voxels to write the interpolated values into.

extentSource - extent corresponding to voxelsSource.

extentDestination - extent corresponding to extentDestination.

Returns:

the destination buffer (either as passed, or a new one that was created).

resizeFloat

public VoxelBuffer<FloatBuffer> resizeFloat(VoxelBuffer<FloatBuffer> voxelsSource,
 VoxelBuffer<FloatBuffer> voxelsDestination,
 Extent extentSource,
 Extent extentDestination)

Description copied from class: VoxelsResizer

Interpolates from voxelsSource to voxelsDestination for float buffers.

Both buffers must be 2-dimensional, not 3-dimensional.

Specified by:

resizeFloat in class VoxelsResizer

Parameters:

voxelsSource - voxels to interpolate from.

voxelsDestination - voxels to write the interpolated values into.

extentSource - extent corresponding to voxelsSource.

extentDestination - extent corresponding to extentDestination.

Returns:

the destination buffer (either as passed, or a new one that was created).

extendWith

public void extendWith(int extendValue)

Switches to extend constant-value out-of-bounds strategy

Parameters:

extendValue - constant-value to use for all values outside the boundary
