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.
