rh (8 bytes): An OfficeArtRecordHeader structure, as defined in section 2.2.1, that specifies the header for this record. The following table specifies the subfields.
-
Field
Meaning
rh.recVer
A value that MUST be 0x0.
rh.recInstance
A value of 0x7A8 to specify one UID, or a value of 0x7A9 to specify two UIDs.
rh.recType
A value that MUST be 0xF01F.
rh.recLen
An unsigned integer that specifies the number of bytes following the header. This value MUST be the size of BLIPFileData plus 17 if recInstance equals 0x7A8, or the size of BLIPFileData plus 33 if recInstance equals 0x7A9.
rgbUid1 (16 bytes): An MD4 message digest, as specified in [RFC1320], that specifies the unique identifier of the uncompressed BLIPFileData.
rgbUid2 (16 bytes): An MD4 message digest, as specified in [RFC1320], that specifies the unique identifier of the uncompressed BLIPFileData. This field only exists if recInstance equals 0x7A9. If this value exists, rgbUid1 MUST be ignored.
tag (1 byte): An unsigned integer that specifies an application-defined internal resource tag. This value MUST be 0xFF for external files.
BLIPFileData (variable): A variable-length field that specifies the DIB data.
