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<FloatBuffer>

Returns:

the number of bytes.

copyKeepOrientation

protected void copyKeepOrientation(ByteBuffer source,
 boolean littleEndian,
 int channelIndexRelative,
 FloatBuffer destination)
                            throws IOException

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<FloatBuffer>

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.

Throws:

IOException - when the operation fails due to read or write IO problems.

copyChangeOrientation

protected void copyChangeOrientation(ByteBuffer source,
 boolean littleEndian,
 int channelIndexRelative,
 FloatBuffer destination,
 OrientationChange orientationCorrection)
                              throws IOException

Description copied from class: ConvertTo

Copy the bytes, changing orientation.

Specified by:

copyChangeOrientation in class ConvertTo<FloatBuffer>

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.

Throws:

IOException - when the operation fails due to read or write IO problems.
