Parameters

data
Pointer to unmanaged memory that holds the data to be compressed.
Remarks
You must call StartCompress(Int32,Int32,Int32,RasterByteOrder,RasterViewPerspective,Int32,Byte[],Int32,Int32,CodecsCompression,CodecsCompressDataCallback) before using this method, and you must call StopCompress to end the compression process. For a description of how these methods work together, refer to StartCompress(Int32,Int32,Int32,RasterByteOrder,RasterViewPerspective,Int32,Byte[],Int32,Int32,CodecsCompression,CodecsCompressDataCallback).
Example
For an example, refer to StartCompress(Int32,Int32,Int32,RasterByteOrder,RasterViewPerspective,Int32,Byte[],Int32,Int32,CodecsCompression,CodecsCompressDataCallback).
