I know this is a Scribus forum, but my question is relevant in that I created an image in Inkscape that appears correctly in Scribus when I import it, but when I send the file to PDF, the image loses all the shading I've done. In the PDF preflight verifier, it does come up with an error saying that I have transparencies in the file, but that has shown up before and when I went through with exporting as a PDF, everything looked fine.
I'm an absolute newbie to Inkscape. I've used DTP programs before, so I feel more comfortable there. But I only started playing around with Inkscape for a couple months.
