Let me point out, though, that on Windows quality would *not* be an issue. The native clipboard format is GDI metafile, which in fact is a vector format. The system does an on-the-fly conversion to a bitmap format only if the requesting application (the one you paste into) does not understand the vector format or otherwise explicitly asks for a raster presentation.
This, I guess (I am not an expert on windows programming), also depends on the source of image. If a user clips from paintbrush or acrobat reader, the format in clipboard has to be in raster format.
Therefore I really do not understand that your .wmf-Files are usable only in SWP.
I am talking about latex here. Standard latex, pdflatex etc do not recognize .wmf file format so there is no way to compile a tex file generated from SWP under *nix (or windows miktex), if it has .wmf files.
Unfortunately there are no good converters WMF <--> EPS.
This is exactly the problem.
Moreover, almost no Windows application is able to export (good) EPS, whereas almost no UNIX application provides native support for WMF. The only exception I am aware of is OpenOffice Draw, which provides high quality EMF and EPS export.
One of the lyx developers has tried to extract wmf handling from openoffice but failed. Bo
