Hi, Noticed today that if you have gradients that go to alpha 0% then they do not show up in a (save copy) PDF.
I have fairly old software, so perhaps my gnome PDF thing is out of date, but when I made the gradients go to white + alpha 100% (i.e. opaque) then the gradients worked in the PDF.
Any word on the rules in this regard?

Evince is quite bad at rendering gradients. the evince devs blame poppler, the poppler devs blame cairo. and the bugs sit around for years. if you want to see what the PDF really looks like you need to use adobe acroread.

(interestingly older version of evince/gpdf could render some of these files better)
