Usage
status = WRead_META( [window_index] )
Input Parameters
window_index — (optional) The index of the window to receive the graphics. If not specified, the current window is assumed. If no window is currently open, an error results.
Returned Value
status — A value indicating success or failure of the read; expected values are:
< 0 — Indicates an error.
0 — Indicates a successful read.
Keywords

Discussion
This function loads an enhanced-format metafile (EMF) into a graphics window. For more information on metafiles, see the description of the WINDOW procedure.
Example
Assume that the file map.emf is an enhanced-format metafile that was exported from a graphics application. The following command reads the contents of that file directly into a graphics window.
status = WREAD_META(2, Filename='map.emf')
