Public Methods

Method	Description
JpegHuffmanTable ( short lengths, short values ) : System	Construct and initialize a Huffman table. Copies are created of the array arguments. lengths[index] stores the number of Huffman values with Huffman codes of length index + 1. The values array stores the Huffman values in order of increasing code length. throws ArgumentException if either parameter is null, if lengths.Length > 16 or values.Length > 256, if any value in length or values is negative, or if the parameters do not describe a valid Huffman table

Private Methods

Method	Description
JpegHuffmanTable ( short lengths, short values, bool copy ) : System	Private constructor that avoids unnecessary copying and argument checking.
checkLengths ( short lengths ) : short[]
checkValues ( short values, short lengths ) : short[]

JpegHuffmanTable() public method

Construct and initialize a Huffman table. Copies are created of the array arguments. lengths[index] stores the number of Huffman values with Huffman codes of length index + 1. The values array stores the Huffman values in order of increasing code length. throws ArgumentException if either parameter is null, if lengths.Length > 16 or values.Length > 256, if any value in length or values is negative, or if the parameters do not describe a valid Huffman table

public JpegHuffmanTable ( short lengths, short values ) : System
lengths	short	an array of Huffman code lengths
values	short	a sorted array of Huffman values
return	System
