[solved] Reduce Gradient Banding
I have created what would amount to being background image for a drawing that using a linear gradient. My problem that I am having is that the gradient has banding. Is there a work around other than to import the image into gimp and add noise? Blurring does not really help any.

Re: Reduce Gradient Banding
I don't believe there is any sort of dithering option. If you see banding in the Inkscape window it's maybe a limitation of your display, rather than banding in the actual image.

You could try rendering the SVG file with something other than Inkscape (e.g., Batik).

That's possible, but I notice that in bug 180693 MenTaLguY confirms that there is a problem with banding in gradients, and it's caused by Inkscape using only 1024 colours for each gradient.

Well I see that does the trick, In opera the gradient looks very good.

That was what I thought too, but I knew that as much trouble as I have went through to make sure the calibration on this monitor was the best it could be I ruled that out (monitor limitation).
I am assuming from that bug report that this is just an issue with inkscape and not me.
Re: Reduce Gradient Banding (Solved)
Yeah, sounds like a definite limitation of Inkscape.
Interesting that you said it displays ok in Opera. I'm running Opera 5 (beta) and on a new pic I've started it's producing really bad banding when Inkscape produces almost no banding.

The version I am using 9.26 an the banding was completely eliminated which made me say whoa ok this gradient is allright.

Can you run 9.5 and the stable version at the same time/Re: Reduce Gradient Banding (Solved)

I believe you can. It installs into a separate folder and I think creates a different folder for your profile also - so there shouldn't be any conflicts. Opera 9.5 introduces some really nice features but it is still quite buggy - inline find doesn't currently work and there has been issues with handling of IMAP mail - but it's good enough that I use it as my primary web browser on my home PC.
