RecordSize (4 bytes): A 32-bit unsigned integer that defines the number of WORDs in the WMF record.

RecordFunction (2 bytes): A 16-bit unsigned integer that defines this WMF record type. The lower byte MUST match the lower byte of the RecordType enumeration (section 2.1.1.1) value META_CREATEPATTERNBRUSH.

Bitmap16 (14 bytes): A partial Bitmap16 object (section 2.2.2.1), which defines parameters for the bitmap that specifies the pattern for the brush. Fields not described below are specified in section 2.2.2.1.

Bits (4 bytes): This field MUST be ignored.

Reserved (18 bytes): This field MUST be ignored.

Pattern (variable): A variable-length array of bytes that defines the bitmap pixel data that composes the brush pattern. The length of this field, in bytes, can be computed from bitmap parameters as follows.

 (((Width * BitsPixel + 15) >> 4) << 1) * Height

The Width, BitsPixel, and Height values are specified in the Bitmap16 field of this record.

The BrushStyle enumeration (section 2.1.1.4) value for the brush object created by this record MUST be BS_PATTERN.

See section 2.3.4 for the specification of other WMF object records.
