http://segaretro.org/File:Real3D_logo.svg extracted from this. Vector graphics in the 90s often found themselves estimating gradients, but due to the anti-aliasing techniques of modern vector standards, this leaves little gaps between every shade. I'm using Inkscape and it doesn't have a formal way of dealing with this (annoyingly common) problem - with simpler images there are hacky ways of getting around it, but this isn't a simple image. Any advice?
Displays just fine in Illustrator, just doesn't like being saved to svg or any of its subformats. I'd just export it as a png:
Yeah, unfortunately older SVG's don't like bringing in gradients seamlessly. The gradient itself gets subdivided into individual vector shapes inside a mask. You can merge the shapes back together, but you lose the gradient and would have to re-create it anyway. You could color sample and write down the hex or rgb values and re-create the gradient yourself, but in terms of re-joining the objects and maintaining the original gradient, probably can't do it; not that I can find anyway. I've never used inkscape, but as far as Illustrator is concerned, there doesn't seem to be an eloquent solution.
