[Inkscape-user] Convert SVG->PDF with transparency

Greetings.

I just created a poster using Inkscape and want to make a PDF version to distribute. I use a lot of transparency in the poster, but unfortunately Inkscape's export filters for Postscript and PDF don't preserve the transparency.

Can someone suggest another SVG to PDF converter which will preserve transparency? I tried Cairo's svg2pdf, but it just segfaults midway through processing the file.

BTW, I'm running GNU/Linux. I do have access to a Windows XP machine, but not to hundreds of dollars to buy expensive Adobe software.

Regards, Tristan
