Displays the picture stored in the specified enhanced-format metafile
#include <WinAPIGdi.au3>
_WinAPI_PlayEnhMetaFile ( $hDC, $hEmf, $tRECT )
| $hDC | Handle to the device context for the output device on which the picture will appear. |
| $hEmf | Handle to the enhanced metafile. |
| $tRECT | $tagRECT structure that contains the coordinates of the bounding rectangle used to display the picture, in logical units |
| Success: | True |
| Failure: | False |
An enhanced metafile can be embedded in a newly created enhanced metafile by calling _WinAPI_PlayEnhMetaFile()
and playing the source enhanced metafile into the device context for the new enhanced metafile.
