The EMF file format has been revised twice. The changed versions are original, extension 1, and extension 2. Extended versions have provision for OpenGL records and an optional descriptor for internal pixel format. A measuring facility in milliliters is added for displayed dimensions. Table of Content. What is an EMF file? Moreover supports the record containing graphics objects and commands for drawing. Version 1 : The second version of EMF improved the flexibility and device independence by adding the record for pixel format and provision to use OpenGL command.
Version 2 : The third version enhanced the accuracy by adding the Metric system to measure the device surface distances, leaving the record more scalable.
Enhanced Metafile Records Metafile records are arranged in the form of array. Enhanced Metafile Operations Following are jobs that can be accomplished using the handle to an enhanced metafile. Display and edit for the stored picture.
Produce enhanced metafile copies. The following code example demonstrates how to create a Metafile and use the PlayRecord method. NET Framework does not have an encoder that you can use to save files as. NET 6 and later versions, the System. Common package , which includes this type, is only supported on Windows operating systems. Use of this type in cross-platform apps causes compile-time warnings and run-time exceptions. For more information, see System.
