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.

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;

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.
