javax.imageio.plugins.jpeg.JPEGHuffmanTable
A class encapsulating a single JPEG Huffman table.
Fields are provided for the standard tables taken
from Annex K of the JPEG specification.
These are the tables used as defaults.
For more information about the operation of the standard JPEG plug-in, see the JPEG metadata format specification and usage notes

->jpeg-huffman-tableclj
(->jpeg-huffman-table lengths values)Constructor.
Creates a Huffman table and initializes it. The input arrays are copied. The arrays must describe a possible Huffman table. For example, 3 codes cannot be expressed with a single bit.
lengths - an array of shorts where lengths[k] is equal to the number of values with corresponding codes of length k 1 bits. - short[]
values - an array of shorts containing the values in order of increasing code length. - short[]
throws: java.lang.IllegalArgumentException - if lengths or values are null, the length of lengths is greater than 16, the length of values is greater than 256, if any value in lengths or values is less than zero, or if the arrays do not describe a valid Huffman table.

For example, 3 codes cannot be expressed with a single bit. lengths - an array of shorts where lengths[k] is equal to the number of values with corresponding codes of length k 1 bits. - `short[]` values - an array of shorts containing the values in order of increasing code length. - `short[]` throws: java.lang.IllegalArgumentException - if lengths or values are null, the length of lengths is greater than 16, the length of values is greater than 256, if any value in lengths or values is less than zero, or if the arrays do not describe a valid Huffman table.
get-lengthsclj
(get-lengths this)Returns an array of shorts containing the number of values for each length in the Huffman table. The returned array is a copy.
returns: a short array where array[k-1]
is equal to the number of values in the table of length k. - short[]
Returns an array of shorts containing the number of values for each length in the Huffman table. The returned array is a copy. returns: a short array where array[k-1] is equal to the number of values in the table of length k. - `short[]`
get-valuesclj
(get-values this)Returns an array of shorts containing the values arranged by increasing length of their corresponding codes. The interpretation of the array is dependent on the values returned from getLengths. The returned array is a copy.
returns: a short array of values. - short[]
Returns an array of shorts containing the values arranged by increasing length of their corresponding codes. The interpretation of the array is dependent on the values returned from getLengths. The returned array is a copy. returns: a short array of values. - `short[]`
to-stringclj
(to-string this)Returns a String representing this Huffman table.
returns: a String representing this Huffman table. - java.lang.String
Returns a String representing this Huffman table. returns: a String representing this Huffman table. - `java.lang.String`
