   ByRef method As ModelRestorationMethod _
) As Boolean

'Usage
 
Dim stream As Stream
Dim allocatorSize As Integer
Dim modelOrder As Byte
Dim method As ModelRestorationMethod
Dim value As Boolean
 
value = ManagedPPMdDecompressor.ReadPPMdZipHeader(stream, allocatorSize, modelOrder, method)

public static bool ReadPPMdZipHeader( 
   Stream stream,
   out int allocatorSize,
   out byte modelOrder,
   out ModelRestorationMethod method
)

Parameters

stream

The stream the header will be read from.

allocatorSize

The allocator size.

modelOrder

The maximum model order.

method

Method of model restoration if memory is insufficient.

Return Value

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 read with the Intel little-endian byte order.

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
