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?
