2.3.12 Transform Record Types

The transform record types specify and modify world-space to page-space transforms.

The following are EMF transform record types.

Name	Section	Description
EMR_MODIFYWORLDTRANSFORM	2.3.12.1	Modifies the current world-space to page-space transform.
EMR_SETWORLDTRANSFORM	2.3.12.2	Specifies a two-dimensional linear transform between world space and page space.

The generic structure of EMF transform records is specified as follows.

0	1	2	3	4	5	6	7	8	9	1 0	1	2	3	4	5	6	7	8	9	2 0	1	2	3	4	5	6	7	8	9	3 0	1

TransformData (optional)

Type (4 bytes): An unsigned integer that defines the type of record. The transform record types are listed in the following table. See the preceding table for descriptions of these record types.

Name	Value
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.
