Metafiles in GDI+
GDI+ provides the xref:System.Drawing.Imaging.Metafile class so that you can record and display metafiles. A metafile, also called a vector image, is an image that is stored as a sequence of drawing commands and settings. The commands and settings recorded in a xref:System.Drawing.Imaging.Metafile object can be stored in memory or saved to a file or stream.
Metafile Formats
GDI+ can display metafiles that have been stored in the following formats:
-
Windows Metafile (WMF)
-
Enhanced Metafile (EMF)
-
EMF+
GDI+ can record metafiles in the EMF and EMF+ formats, but not in the WMF format.
EMF+ is an extension to EMF that allows GDI+ records to be stored. There are two variations on the EMF+ format: EMF+ Only and EMF+ Dual. EMF+ Only metafiles contain only GDI+ records. Such metafiles can be displayed by GDI+ but not by GDI. EMF+ Dual metafiles contain GDI+ and GDI records. Each GDI+ record in an EMF+ Dual metafile is paired with an alternate GDI record. Such metafiles can be displayed by GDI+ or by GDI.
The following example displays a metafile that was previously saved as a file. The metafile is displayed with its upper-left corner at (100, 100).
