ByteLookupTable back to summary

ByteLookupTable	back to summary
public ByteLookupTable(int offset, byte[][] data) 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:int the value subtracted from the input values before indexing into the arrays data:byte[][] an array of byte arrays representing a lookup table for each band Exceptions 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. 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:int: the value subtracted from the input values before indexing into the arrays
data:byte[][]: an array of byte arrays representing a lookup table for each band

Exceptions

IllegalArgumentException:: if offset is is less than 0 or if the length of data is less than 1

Parameters offset:int the value subtracted from the input values before indexing into the array data:byte[] an array of bytes Exceptions 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 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:int: the value subtracted from the input values before indexing into the array
data:byte[]: an array of bytes

Exceptions

IllegalArgumentException:: if offset is is less than 0 or if the length of data is less than 1

getTable back to summary

getTable	back to summary
public final byte[][] getTable() 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:byte[][] the data array of this `ByteLookupTable`.

public final byte[][] getTable()

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:byte[][]: the data array of this ByteLookupTable.

lookupPixel back to summary

lookupPixel	back to summary
public int[] lookupPixel(int[] src, int[] dst) Implements abstract java.awt.image.LookupTable.lookupPixel. 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. Parameters src:int[] the source array. dst:int[] 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`. Returns:int[] the array `dst`, an `int` array of samples. Exceptions 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.

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

Implements abstract java.awt.image.LookupTable.lookupPixel.

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.

Parameters

src:int[]: the source array.
dst:int[]: 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.

Returns:int[]

the array dst, an int array of samples.

Exceptions

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.

lookupPixel back to summary

lookupPixel	back to summary
public byte[] lookupPixel(byte[] src, byte[] dst) 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. Parameters src:byte[] the source array. dst:byte[] 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`. Returns:byte[] the array `dst`, an `int` array of samples. Exceptions 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 byte[] lookupPixel(byte[] src, byte[] dst)

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.

Parameters

src:byte[]: the source array.
dst:byte[]: 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.

Returns:byte[]

the array dst, an int array of samples.

Exceptions

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.
