C++
public void CopyData(  
   byte[] data, 
   int dataOffset 
) 
Public Overloads Sub CopyData( _ 
   ByVal data() As Byte, _ 
   ByVal dataOffset As Integer _ 
)  
public void copyData( 
  byte[] data,  
  int dataOffset,  
  long size 
) 
public: 
void CopyData(  
   array<byte>^ data, 
   int dataOffset 
)  

Parameters

data
Buffer containing the image new data.

dataOffset
Offset into data where the copy operation should begin.

Remarks

The byte array that you specify will be copied.

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