Fields

CompLength

The compressed data length in bytes.

public uint CompLength

Field Value

uint

Compression

The compression type for this hunk.

public byte Compression

Field Value

byte

CompressionNone

No compression; hunk data is stored verbatim.

Field Value

byte

CompressionParent

Hunk data is filled from the parent image.

public const byte CompressionParent = 6

Field Value

byte

CompressionSelf

Field Value

byte

CompressionType0

Compression type 0 (deflate codec 0).

public const byte CompressionType0 = 0

Field Value

byte

CompressionType1

Compression type 1 (deflate codec 1).

public const byte CompressionType1 = 1

Field Value

byte

CompressionType2

Compression type 2 (deflate codec 2).

public const byte CompressionType2 = 2

Field Value

byte

CompressionType3

Compression type 3 (deflate codec 3).

public const byte CompressionType3 = 3

Field Value

byte

Crc16

CRC-16 checksum of the uncompressed hunk data.

public ushort Crc16

Field Value

ushort

Offset

The byte offset to the hunk data within the file.

public ulong Offset

Field Value

ulong
