)

'Declaration
 
Public Overloads Sub CopyData( _
   ByVal data() As Byte, _
   ByVal dataOffset As Integer _
)

'Usage
 
Dim instance As RasterImage
Dim data() As Byte
Dim dataOffset As Integer
 
instance.CopyData(data, dataOffset)

public void CopyData( 
   byte[] data,
   int dataOffset
)

public void copyData(
  byte[] data, 
  int dataOffset, 
  long size
)

 function Leadtools.RasterImage.CopyData(Byte[],Int32)( 
   data ,
   dataOffset 
)

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.

The byte array that you specify will be copied.

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