Using Writer to publish to directly to WordPress blog

I’m trying to find an extension that would allow me to directly publish from writer to my WordPress blog. Is this possible?

I have found Sun Weblog Publisher but it seems hard to get to work and is really dated. Is there another tool that can be used?

Windows 8.1 64 bit English
LibreOffice Writer from LibreOffice version: 4.3.5.2 English

Thanks
John
