Contents
[
Hide
]Summary: The HeaderExtension1 object defines the first extension to the EMF metafile header.
It adds support for a PixelFormatDescriptor object (section 2.2.22) and OpenGL
[OPENGL] records (section 2.3.9).

Properties
| Name | Type | Access | Description |
|---|---|---|---|
| b_open_gl | int | r/w | Gets or sets a 32-bit unsigned integer that indicates whether OpenGL commands are present in the metafile. 0x00000000 OpenGL records are not present in the metafile. 0x00000001 OpenGL records are present in the metafile. |
| bounds | Rectangle | r/w | Gets or sets a WMF RectL object ([MS-WMF] section 2.2.2.19) that specifies the rectangular inclusive-inclusive bounds in device units of the smallest rectangle that can be drawn around the image stored in the metafile |
| bytes | int | r/w | Gets or sets 32-bit unsigned integer that specifies the size of the metafile, in bytes. |
| cb_pixel_format | int | r/w | Gets or sets a 32-bit unsigned integer that specifies the size of the PixelFormatDescriptor object. This MUST be 0x00000000 if no pixel format is set |
| device | Size | r/w | Gets or sets a WMF SizeL object ([MS-WMF] section 2.2.2.22) that specifies the size of the reference device, in pixels |
| frame | Rectangle | r/w | Gets or sets a WMF RectL object that specifies the rectangular inclusive-inclusive dimensions, in .01 millimeter units, of a rectangle that surrounds the image stored in the metafile |
| handles | short | r/w | Gets or sets a 16-bit unsigned integer that specifies the number of graphics objects that will be used during the processing of the metafile |
| millimeters | Size | r/w | Gets or sets a WMF SizeL object that specifies the size of the reference device, in millimeters |
| n_desription | int | r/w | Gets or sets a 32-bit unsigned integer that specifies the number of characters in the array that contains the description of the metafile’s contents. This is zero if there is no description string. |
| n_pal_entries | int | r/w | Gets or sets a 32-bit unsigned integer that specifies the number of entries in the metafile palette. The palette is located in the EMR_EOF record |
| off_description | int | r/w | Gets or sets a 32-bit unsigned integer that specifies the offset from the beginning of this record to the array that contains the description of the metafile’s contents |
| off_pixel_format | int | r/w | Gets or sets a 32-bit unsigned integer that specifies the offset to the PixelFormatDescriptor object. This MUST be 0x00000000 if no pixel format is set. |
| record_signature | EmfFormatSignature | r/w | Gets or sets a 32-bit unsigned integer that specifies the record signature. This MUST be ENHMETA_SIGNATURE, from the FormatSignature enumeration (section 2.1.14). |
| records | int | r/w | Gets or sets a 32-bit unsigned integer that specifies the number of records in the metafile |
| reserved | short | r/w | Gets or sets a 16-bit unsigned integer that MUST be 0x0000 and MUST be ignored |
| valid | bool | r | Gets a value indicating whether this EmfHeaderObject is valid. |
| version | int | r/w | Gets or sets Version (4 bytes): A 32-bit unsigned integer that specifies EMF metafile interoperability. This SHOULD be 0x00010000 |
