Hello,
im trying to convert a svg file to png under Linux (Debian)
Almost every thing works fine.
I only have a problem with the tag "textPath".
After convert from svg to png the text is not printed along the path. (see below)
Is this a problem which will be fixed in the future? (I'm runing 6.2.4.5)
Code: Select all
<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="1000px" height="707px" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<defs>
<path id="MyPath" d="M 599,455 A 244,244 0 0,1 723,578" />
</defs>
<use xlink:href="#MyPath" fill="none" stroke="red" />
<text font-family="Verdana" font-size="42.5" fill="blue" >
<textPath xlink:href="#MyPath">
We go up, then we go down, then up again
</textPath>
</text>
</svg>
Thanks

textPath is not implemented in the built-in SVG converter of IM. However if available IM will use the libRSVG library to do SVG conversion, and this does get it right.
Also a perl module has been release to externally implement text path using Perl-Magick

Try the latest 6.3.8 version. There was a small change to the svg lib, that may help your cause.

Thanks for the advise. I tried today 6.3.8 version but with almost the same result
http://creatiese.com/test.svg
http://creatiese.com/test.png
It seems that the bugfix (Set RSVG base URI (patch provided by tsdineen).) helped a bit.
Can it be, that imagemagick has a problem to match "textPath" and "path" by id?
Thanks

What happens when you use rsvg directly?
rsvg test.svg test.png
It's possible that there is some missing initialization code in the svg.so that may be in th rsvg main code.

Thanks for the tip.
There were no runtime script under the "librsvg2-dev" debian package.
So I installed librsvg-2.20.0 from source and got the same result ('rsvg test.svg test.png' =>no Text around the graph) with no warnings.
It seems that the problem comes with the rsvg package and not with ImageMagick.
At the end I tried to convert svg to png with inkscape and it works.
Has someone successful convert svg (with textPath) to png under ImageMagick? I'm not quit sure if that is generell problem or just a wrong configuration of my server.
For the moment I have a solution (inkscape), but I still like to find the real cause.
Thanks

I've not tried the converion you mentioned, but I am also using a different version of rsvg. I believe I am using the last verison before they started using Cario, which is 2.12.7.

The run time programs are often installed using a different package to the library itself. Under fedora they are part of the library package but that may not be the case under debian.
Fedora package included the programs, rsvg, rsvg-convert, rsvg-view, along with the library.
My version of IM also did not convert the text in the SVG provided. But then neither did RSVG, which is not suprising, considering that my IM uses the same library.
The RSVG is a full SVG implementation and I have see it do text paths, so I say something is wrong with the SVG, even though my firefox offical Adobe implementation displays it as expected.
