ByteLookupTable JDK 1.6)

Constructors

public ByteLookupTable (int offset, byte[] data)

Constructs a ByteLookupTable object from an array of bytes representing a lookup table to be applied to all bands.

Constructs a ByteLookupTable object from an array
of bytes representing a lookup table to be applied to all
bands. The offset will be subtracted from input
values before indexing into the array.
The data array is stored as a reference.
Parameters:
- offset - the value subtracted from the input values before indexing into the array
- data - an array of bytes
Throws:
- IllegalArgumentException - if offset is is less than 0 or if the length of data is less than 1

public ByteLookupTable (int offset, byte[][] data)

Constructs a ByteLookupTable object from an array of byte arrays representing a lookup table for each band.

Constructs a ByteLookupTable object from an array of byte
arrays representing a lookup table for each
band. The offset will be subtracted from input
values before indexing into the arrays. The number of
bands is the length of the data argument. The
data array for each band is stored as a reference.
Parameters:
- offset - the value subtracted from the input values before indexing into the arrays
- data - an array of byte arrays representing a lookup table for each band
Throws:
- IllegalArgumentException - if offset is is less than 0 or if the length of data is less than 1

Methods

Hide/Show inherited methods

public int getNumComponents () [Inherited From LookupTable]

Returns the number of components in the lookup table.

Returns the number of components in the lookup table.
Returns: the number of components in this LookupTable.

public int getOffset () [Inherited From LookupTable]

Returns the offset.

Returns the offset.
Returns: the offset of this LookupTable.

publicfinal byte getTable ()

Returns the lookup table data by reference.

Returns the lookup table data by reference. If this ByteLookupTable
was constructed using a single byte array, the length of the returned
array is one.
Returns: the data array of this ByteLookupTable.

public byte lookupPixel (byte[] src, byte[] dst)

Returns an array of samples of a pixel, translated with the lookup table.

Returns an array of samples of a pixel, translated with the lookup
table. The source and destination array can be the same array.
Array dst is returned.
Returns: the array dst, an int array of samples.
Parameters:
- src - the source array.
- dst - the destination array. This array must be at least as long as src. If dst is null, a new array will be allocated having the same length as src.
Throws:
- ArrayIndexOutOfBoundsException - if src is longer than dst or if for any element i of src, (src[i]&0xff)-offset is either less than zero or greater than or equal to the length of the lookup table for any band.

public int lookupPixel (int[] src, int[] dst) [Specified in LookupTable]

Returns an array of samples of a pixel, translated with the lookup table.

Returns an array of samples of a pixel, translated with the lookup
table. The source and destination array can be the same array.
Array dst is returned.
Returns: the array dst, an int array of samples.
Parameters:
- src - the source array.
- dst - the destination array. This array must be at least as long as src. If dst is null, a new array will be allocated having the same length as src.
Throws:
- ArrayIndexOutOfBoundsException - if src is longer than dst or if for any element i of src, src[i]-offset is either less than zero or greater than or equal to the length of the lookup table for any band.
