Back in 8.04 and 10.04, GIMP could easily open WMF files, letting me work on them.
In 11.04, there was a regression (still not fixed!), and this would not work.
But at least there was a workaround. You could convert WMF files to EPS and work on them.
wmf2eps --wmf-fontdir=/usr/share/fonts/type1/gsfonts -o outputfile.eps inputfile.wmf
However, now we have 12.04, and not even the workaround works any more; it is unable to convert the file. There is no error message; it just fails with error code 1.
Despite Inkscapes claims to be a plausible solution (workaround) Inkscape simply opened the WMF image as a completely empty image, with no error message.
I need to work on WMF files quite urgently. Does anyone know what I can do, whether work-around or (preferably) a fix?
Have you tried Inkscape
Inkscape's import for WMF is quite mature, and most WMF files can be imported without issues. You will have the ability to convert WMF file with something that is compatible with GIMP
You can download it from the Ubuntu Software Center
