DecodeACFirst ( JPEGBinaryReader stream, float zz ) : void
DecodeACRefine ( JPEGBinaryReader stream, float dest ) : void
DecodeBaseline ( JPEGBinaryReader stream, float dest ) : void
DecodeDCFirst ( JPEGBinaryReader stream, float dest ) : void
DecodeDCRefine ( JPEGBinaryReader stream, float dest ) : void
DecodeMCU ( JPEGBinaryReader jpegReader, int i, int j ) : void
JpegComponent ( JpegScan parentScan, byte id, byte factorHorizontal, byte factorVertical, byte quantizationID, byte colorMode ) : System
SetBlock ( int idx ) : void
decode_dc_coefficient ( JPEGBinaryReader JPEGStream ) : float	Generated from text on F-22, F.2.2.1 - Huffman decoding of DC coefficients on ISO DIS 10918-1. Requirements and Guidelines.
idctData ( ) : void	Run the Inverse DCT method on all of the block data
padMCU ( int index, int length ) : void	If a restart marker is found with too little of an MCU count (i.e. our Restart Interval is 63 and we have 61 we copy the last MCU until it's full)
quantizeData ( ) : void	Run the Quantization backward method on all of the block data.
resetInterval ( ) : void	Reset the interval by setting the previous DC value
scaleByFactors ( BlockUpsamplingMode mode ) : void	Stretches components as needed to normalize the size of all components. For example, in a 2x1 (4:2:2) sequence, the Cr and Cb channels will be scaled vertically by a factor of 2.
setACTable ( JpegHuffmanTable table ) : void
setDCTable ( JpegHuffmanTable table ) : void
writeBlock ( byte raster, byte data, int compIndex, int x, int y ) : void
writeDataScaled ( byte raster, int componentIndex, BlockUpsamplingMode mode ) : void
