Parameters

decompressContext

The decompressing context object obtained through StartDecompress.

data

A pointer to an unmanaged memory buffer that contains the raw compressed data.

dataOffset

Offset of the strip referenced by data, This is usually zero.

dataLength

Number of bytes in data.

width

Width of the uncompressed strip or tile, in bytes

height

Height of the uncompressed strip or tile, in bytes. If the image consists of a single compressed strip, as with TWAIN, this is the height of the image.

row

Row offset of the tile or strip.

column

Column offset of the tile or strip.

flags

Flags that indicate whether which part of a strip or tile is being processed. Possible values are:

Value	Meaning
CodecsDecompressDataFlags.Start	Processing the beginning of a tile or strip
CodecsDecompressDataFlags.End	Processing the end of a tile or strip
CodecsDecompressDataFlags.Complete	Process a complete tile or strip. This is the same as CodecsDecompressDataFlags.Start | CodecsDecompressDataFlags.End

Note that you must call the StartDecompress method before using this method, and you must call the StopDecompress method to end the decompression process.

If data does not point to a full tile or strip, set flags to CodecsDecompressDataFlags.Start when the tile/strip begins and set it to CodecsDecompressDataFlags.End when the tile/strip ends.

Target Platforms: Silverlight, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7, MAC OS/X (Intel Only)
