ADAPTIVE HUFFMAN COMPRESSION
----------------------------
C# implementation of adaptive Huffman compression.
Example
-------
// Read in the file and write it out compressed
using (FileStream input = new FileStream(@"C:\test.txt", FileMode.Open))
{
using (FileStream output = new FileStream(@"C:\compressed.ahd", FileMode.Create))
{
AdaptiveHuffmanProvider.Compress(input, output);
}
}
Classes
-------
AdaptiveHuffmanCompression.cs classes
- AdaptiveHuffmanProvider
- Static methods to help compress and decompress bytes and streams using adaptive Huffman compression
- Uses AdaptiveHuffmanStream for compression
- AdaptiveHuffmanStream
- Stream implementation using adaptive Huffman compression to compress and decompress written and read bytes.
- Implements both FGK and Vitter algorithms (currently set to use FGK)
BitStream.cs classes
- BitStream
- Stream implementation for reading and writing individual bits from and to the stream.
- Used by AdaptiveHuffmanStream
Enjoy,
Steve
