Hi Máirín,

Could you attach your example svg file to the bug report so we can see the new fedora background svg? It's currently a 403.

I seem to remember this issue being stuck in the horrid edge of the world that is cairo. So a proper fix would likely involve kicking cairo up the backside or doing something else for rendering. All quite hard.

But with €32.000,00 who knows what might be possible.

What do others think? Is could we do with some fundraising and developer attention help on this particular issue?

Best Regards, Martin Owens

Hi Inkscape developers!

There is an old open ticket about gradient banding issues in Inkscape -  https://bugs.launchpad.net/inkscape/+bug/180693 - and the Fedora Design  Team hit it pretty hard when putting together the Fedora 25 background  in Inkscape. It's a difficult problem because there aren't many  workarounds. We weren't able to fully remove the banding in our final  version.

We're designers without much development experience so we can't fix the  problem, but we have a lot of interest in doing whatever we can to help.  One of our team members suggested trying a crowdfunding approach like  Krita has done, e.g. -

https://www.kickstarter.com/projects/krita/krita-2016-lets-make-text- and-vector-art-awesome

I wanted to run this idea by you and see what you think about it. We  don't want to apply any unwanted pressure, and realize anyone taking on  the bug who isn't already a part of your team would need mentorship /  help from you, so I don't think it'd be a good idea to try this unless  you were willing to be involved.

Let me know what you think about this, or if you have any other ideas on  how we might be able to help!

Thanks!!

I assume the the problem is in the exported PNG files. As Martin mentioned, the best place to fix this in the Cairo library. It's difficult to deal with after the gradients are generated. We do have a board member who works on Cairo so if we provide the code, we have a route to getting it into Cairo.

We've been trying to organize funding for projects but its been taking a long time.[1] We could use a lot of help in this area.
