Hey guys, so I'm having a bit of trouble saving my work as a .pdf format. So it' saved just fine, but there are a few objects that are missing from the .pdf page. Everything that I've used the mask function on is still there on my Inkscape document, but has disappeared on on the .pdf. I'm not quite sure what I'm doing wrong, but if anyone could give me a bit of advice, that'd be great.

PS- I'm on a bit of a deadline, so help is very needed.

Thanks guys!

If vectors are not a must -like if you use blur filter-, you can export the missing parts to png and make a pdf with those embedded instead.

Did you use an object with gradient for masking or something similar?
If it's for masking with solid white, try clipping instead, which is more reliable.

Wow. It was that easy. All I needed to do was clip instead of mask, and it works now. Thanks a ton mate!
