I'm having problems with the <linearGradient> SVG tag. The below source gives unexpected output.

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">

</linearGradient>
<circle fill="url(#SVGID_1_)" cx="6.5004883" cy="6.5" r="4.8891602"/>

Expect something similar to:

With ImageMagick-6.4.9-4-Q16 I get:

Any ideas as to how to solve this?

thanks in advance

Gradient support is not complete in ImageMagick. Are you running under Linux? If so, download / install the very latest ImageMagick release, 6.4.9-4 and it should fix the problem. If you are running under Windows, it will not render properly.

Sadly I run windows. Will use an embedded image until the gradient feature is ready.

Any idea when the gradient support will be done?

Thanks.

We do not currently have an ETA on enhanced gradient support within ImageMagick.

That SVG file also seems to behave differently with RSVG than with MSVG
and I do not mean shape or gradient.

The RSVG output has a weird extra circle of dots around the green circle, which does not exist in the internal MSVG handling.

Compare...
convert -density 500 source.svg show:
with
convert -density 500 MSVG:source.svg show:

on an IM with RSVG compile-time support.

The line is at the interface between the gradient and the background which you can see when you apply

convert -background red -density 500 t show:

I do not see this effect with the command "rsvg-view" so it must be cause by how IM is overlaying the RSVG output on to the background.
