Syntax
'Declaration
 
Public Shared Sub WritePPMdZipHeader( _
   ByVal stream As Stream, _
   ByVal allocatorSize As Integer, _
   ByVal modelOrder As Byte, _
   ByVal method As ModelRestorationMethod _
) 
'Usage
 
Dim stream As Stream
Dim allocatorSize As Integer
Dim modelOrder As Byte
Dim method As ModelRestorationMethod
 
ManagedPPMdCompressor.WritePPMdZipHeader(stream, allocatorSize, modelOrder, method)
public static void WritePPMdZipHeader( 
   Stream stream,
   int allocatorSize,
   byte modelOrder,
   ModelRestorationMethod method
)

Parameters

stream
The stream the header will be written to.
allocatorSize
The allocator size.
modelOrder
The maximum model order.
method
Method of model restoration if memory is insufficient.
Remarks

The header is 2 bytes long and has the following format. In C, the header would be defined like this (from least-significant to most-significant bit):

struct PPMdZipHeader
{
  unsigned short modelOrder : 4;
  unsigned short AllocatorSize : 8;
  unsigned short Method : 4;
};

The values are written in Intel little-endian byte order.

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
