The following package has been updated in the Cygwin distribution:

* mscgen-0.20-2

Mscgen is a small programme that parses Message Sequence Chart
descriptions and produces PNG, SVG, EPS or server side image maps
(ismaps) as the output.

This release has been built with libgd3 and three patches from Fedora.
Please rebuild the package with
        configure --with-freetype
so the font selection option -F can be used.

I tried rebuilding with '--with-freetype'. mscgen builds but always exits with an error code. This is because gdImageStringFT() always returns the string 'Could not set character size'. By default, the code is trying to use the 'helvetica' font. I have a goodly selection of font packages installed. Any ideas?
I had similar problems until I found out how to configure fonts. This is very poorly documented. With /etc/fonts/fonts.conf pointing to ~/.fonts, it is actually sufficient to link your font directory to ~/.fonts and you can address all fonts contained therein (including subfolders) by their name like in
mscgen -T png -F "Droid Sans"

I'm not sure you need to edit /etc/fonts/fonts.conf. By default, this includes /usr/share/fonts, so any font therein should be accessible to mscgen. You would only need to do this if you wanted to use fonts in non-standard locations - such as those from texlive-collection-fontsextra.

I wonder if this is a problem with font types? 'fc-match helvetica' matches a PCF font, and that might explain the error, if libgd3 is trying to scale a bitmap font. But a TrueType Font such as 'Luxi Sans' works. Should I just patch mscgen so that the default font is a TrueType font?
