GTK+ installs binary loaders, e.g.:

  ole:~$ ls /usr/lib/gtk-2.0/2.4.0/loaders
  libpixbufloader-ani.la   libpixbufloader-pcx.la  libpixbufloader-tiff.la
  libpixbufloader-ani.so   libpixbufloader-pcx.so  libpixbufloader-tiff.so
  libpixbufloader-bmp.la   libpixbufloader-png.la  libpixbufloader-wbmp.la
  libpixbufloader-bmp.so   libpixbufloader-png.so  libpixbufloader-wbmp.so
  libpixbufloader-gif.la   libpixbufloader-pnm.la  libpixbufloader-xbm.la
  libpixbufloader-gif.so   libpixbufloader-pnm.so  libpixbufloader-xbm.so
  libpixbufloader-ico.la   libpixbufloader-ras.la  libpixbufloader-xpm.la
  libpixbufloader-ico.so   libpixbufloader-ras.so  libpixbufloader-xpm.so
  libpixbufloader-jpeg.la  libpixbufloader-tga.la  svg_loader.so
  libpixbufloader-jpeg.so  libpixbufloader-tga.so

You can ask what MIME types they support with
'gdk-pixbuf-query-loaders'. So if you want another format, I think you
have two options: either write a back-end loader for GTK+ (which
anyone can then use) or write a custom one which simply converts the
vector format into the Gdk::Pixbuf format (four bytes pr. pixel,
RGBA).

Or you could always use the 'convert' program from ImageMagick to
convert the image (perhaps ImageMagick even provides an in-program
representation you can use).
