Class EmfHeaderExtension2

EmfHeaderExtension2 class

The HeaderExtension2 object defines the second extension to the EMF metafile header. It adds the ability to measure device surfaces in micrometers, which enhances the resolution and scalability of EMF metafiles.

Properties

NameDescription
Bounds { get; set; }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 { get; set; }Gets or sets 32-bit unsigned integer that specifies the size of the metafile, in bytes.
Device { get; set; }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 { get; set; }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 { get; set; }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
MicrometersX { get; set; }Gets or sets the 32-bit horizontal size of the display device for which the metafile image was generated, in micrometers
MicrometersY { get; set; }Gets or sets the 32-bit vertical size of the display device for which the metafile image was generated, in micrometers.
Millimeters { get; set; }Gets or sets a WMF SizeL object that specifies the size of the reference device, in millimeters
NDesription { get; set; }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.
NPalEntries { get; set; }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
OffDescription { get; set; }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
Records { get; set; }Gets or sets a 32-bit unsigned integer that specifies the number of records in the metafile
RecordSignature { get; set; }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).
Reserved { get; set; }Gets or sets a 16-bit unsigned integer that MUST be 0x0000 and MUST be ignored
Valid { get; }Gets a value indicating whether this EmfHeaderObject is valid.
Version { get; set; }Gets or sets Version (4 bytes): A 32-bit unsigned integer that specifies EMF metafile interoperability. This SHOULD be 0x00010000
