Summary
Defines a graphic metafile.
Description
The TGPMetafile class defines a graphic metafile. A metafile contains records that describe a sequence of graphics API calls. Metafiles can be recorded (constructed) and played back (displayed). Remarks Some Metafile constructors (those that receive a device context handle) create Metafile objects that are used to record metafiles. Other Metafile constructors (those that do not receive a device context handle) create Metafile objects that are used to display (play back) metafiles.
