UnsignedByteFromUnsignedInt

public class UnsignedByteFromUnsignedInt
extends ToUnsignedByteWithScaling

Converts data of type unsigned int to unsigned byte.

If more than 8-bits are being used in the input values, scaling is applied to map the range of effective-bits (how many bits are used) to an 8-bit range.

Constructor Details

UnsignedByteFromUnsignedInt

public UnsignedByteFromUnsignedInt(int effectiveBits)

Create with a number of effective-bits.

Parameters:

effectiveBits - the number of bits that are used in the input-type e.g. 8 or 12 or 16.

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.

extractScaledValue

protected int extractScaledValue(byte[] sourceArray,
 int index,
 boolean littleEndian)

Description copied from class: ToUnsignedByteWithScaling

Extracts a value from the source-array, and apply any scaling and clamping.

Specified by:

extractScaledValue in class ToUnsignedByteWithScaling

Parameters:

sourceArray - the bytes from which some values are extracted.

index - the offset in sourceArray from which a value is read.

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

Returns:

the extracted value.
