ENHMETAHEADER3 structure (gdiplusmetaheader.h)

The ENHMETAHEADER3 structure contains enhanced-metafile data including the dimensions of the metafile image, the number of records in the metafile, and the resolution of the device on which the metafile was created.

Syntax

typedef struct {
  DWORD iType;
  DWORD nSize;
  RECTL rclBounds;
  RECTL rclFrame;
  DWORD dSignature;
  DWORD nVersion;
  DWORD nBytes;
  DWORD nRecords;
  WORD  nHandles;
  WORD  sReserved;
  DWORD nDescription;
  DWORD offDescription;
  DWORD nPalEntries;
  SIZEL szlDevice;
  SIZEL szlMillimeters;
} ENHMETAHEADER3;

Members

iType

Type: DWORD

Record type. Value is always EMR_HEADER.

nSize

Type: DWORD

Structure size, in bytes. This may be greater than the value returned by sizeof(ENHMETAHEADER3).

rclBounds

Type: RECTL

Bounding rectangle, in device units, for the image stored in the metafile.

rclFrame

Type: RECTL

Rectangle, in 0.01 millimeter units, that surrounds the image stored in the metafile.

dSignature

Type: DWORD

Must be ENHMETA_SIGNATURE.

nVersion

Type: DWORD

Version number of the metafile format. The current version is 0x10000.

nBytes

Type: DWORD

Size, in bytes, of the metafile.

nRecords

Type: DWORD

Number of records in the metafile.

nHandles

Type: WORD

Number of handles in the metafile handle table. Handle index zero is reserved.

sReserved

Type: WORD

Reserved. Must be zero.

nDescription

Type: DWORD

Number of characters in the string that contains the description of the metafile's contents. This member is 0 if the metafile does not have a description string.

offDescription

Type: DWORD

Offset from the beginning of the ENHMETAHEADER3 structure to the string that contains the description of the metafile's contents. This member is 0 if the metafile does not have a description string.

nPalEntries

Type: DWORD

Number of entries in the metafile palette.

szlDevice

Type: SIZEL

Resolution, in pixels, of the reference device.

szlMillimeters

Type: SIZEL

Resolution, in millimeters, of the reference device.
