Value
Meaning
EMRI_ENGINE_FONT_EXT
0x0000000F
This type of record specifies an offset to a TrueType font within a page content record.
EMRI_TYPE1_FONT_EXT
0x00000010
This type of record specifies an offset to a PostScript Type 1 font within a page content record.
EMRI_DESIGNVECTOR_EXT
0x00000011
This type of record specifies an offset to a TrueType font design vector within a page content record.
EMRI_SUBSET_FONT_EXT
0x00000012
This type of record specifies an offset to embedded subset fonts within a page content record.
EMRI_DELTA_FONT_EXT
0x00000013
This type of record specifies an offset to embedded delta fonts within a page content record.
EMRI_EMBED_FONT_EXT
0x00000015
This type of record specifies an offset to embedded font identifiers within a page content record.
cjSize (4 bytes): A 32-bit unsigned integer that specifies the size, in bytes, of the data attached to the record. The size of each record in EMF spool format MUST be aligned to a multiple of 4 bytes.
OffsetLow (4 bytes): The lower 32 bits of a 64-bit unsigned integer that contains the font offset.
OffsetHigh (4 bytes): The upper 32 bits of a 64-bit unsigned integer that contains the font offset.
The offset is the number of bytes from the start of the offset record to the start of a font definition (section 2.2.3.3) record, which is embedded within a page content record. Font definition records are embedded in EMR_COMMENT_EMFSPOOL records, as specified in [MS-EMF] section 2.3.3.3.
