Class UnsignedByteFromFloat

Object

ConvertTo<UnsignedByteBuffer>

ToUnsignedByte

UnsignedByteFromFloat

public class UnsignedByteFromFloat
extends ToUnsignedByte

Converts a ByteBuffer encoding a float type to unsigned byte type, as expected in an Anchor VoxelBuffer.

Only values in the range 0 <= value <= 255 are preserved. Any values outside this range are clamped to 0 or 255.

Any decimal component is dropped.

UnsignedByteFromFloat

public UnsignedByteFromFloat()

Method Details

bytesPerVoxel

protected int bytesPerVoxel()

Description copied from class: ConvertTo

The number bytes to describe each source-voxel.

Specified by:

bytesPerVoxel in class ConvertTo<UnsignedByteBuffer>

Returns:

the number of bytes.

supportsMultipleChannelsPerSourceBuffer

protected boolean supportsMultipleChannelsPerSourceBuffer()

Description copied from class: ConvertTo

Whether the source buffer can encode more than one channel?

Specified by:

supportsMultipleChannelsPerSourceBuffer in class ConvertTo<UnsignedByteBuffer>

Returns:

true if this possible (either with interleaving or with RGB-encoded voxels), false if a buffer will always describe one channel only.

copyKeepOrientation

protected void copyKeepOrientation(ByteBuffer source,
 boolean littleEndian,
 int channelIndexRelative,
 UnsignedByteBuffer destination)

Description copied from class: ConvertTo

Copy the bytes, without changing orientation.

This is kept separate to ConvertTo.copyChangeOrientation(java.nio.ByteBuffer, boolean, int, T, org.anchoranalysis.image.core.dimensions.OrientationChange) as it can be done slightly more efficiently.

Specified by:

copyKeepOrientation in class ConvertTo<UnsignedByteBuffer>

Parameters:

source - the buffer we copy all channels from.

littleEndian - true iff the bytes in source are in little-endian order.

channelIndexRelative - 0 if the buffer is non interleaved, or otherwise the index of the channel among the interleaved channels.

destination - finds an appropriate destination channel for a particular relative-channel-index.

copyChangeOrientation

protected void copyChangeOrientation(ByteBuffer source,
 boolean littleEndian,
 int channelIndexRelative,
 UnsignedByteBuffer destination,
 OrientationChange orientationCorrection)

Description copied from class: ConvertTo

Copy the bytes, changing orientation.

Specified by:

copyChangeOrientation in class ConvertTo<UnsignedByteBuffer>

Parameters:

source - the buffer we copy all channels from.

littleEndian - true iff the bytes in source are in little-endian order.

channelIndexRelative - 0 if the buffer is non interleaved, or otherwise the index of the channel among the interleaved channels.

destination - finds an appropriate destination channel for a particular relative-channel-index.

orientationCorrection - any correction of orientation to be applied as bytes are converted.
