EMR_SETWORLDTRANSFORM
0x00000023
EMR_MODIFYWORLDTRANSFORM
0x00000024
Size (4 bytes): An unsigned integer that specifies the size in bytes of this record in the metafile. This value MUST be a multiple of 4 bytes.
Xform (24 bytes): An XForm object (section 2.2.28), which defines a world-space to page-space transform.
TransformData (4 bytes, optional): An unsigned integer that specifies an additional parameter for the record.
See section 2.3 for more EMF record types.
