public void CopyData( 
   IBuffer data,
   int dataOffset
)

 function Leadtools.RasterImage.CopyData(IBuffer,Int32)( 
   data ,
   dataOffset 
)

public:
void CopyData( 
   IBuffer^ data,
   int dataOffset
)

Parameters

data: Buffer containing the image new data.
dataOffset: Offset into data where the copy operation should begin.

The byte array that you specify will be copied.

The data is copied as is into the internal memory of this RasterImage.
