Greetings, Fellow Debianists,
this is not actually a bug report but something that might concern us
all as a matter of Free Software use inside the Debian project:
The Debian logo file at http://www.debian.org/logos/openlogo.svg
fails to load in the much-respected SVG-based graphics editor Inkscape
(which I use daily and which works fine also for svg files not
produced by itself).
The error is this:
$ inkscape openlogo.svg
openlogo.svg:18: namespace warning : xmlns: URI &ns_svg; is not absolute
xmlns="&ns_svg;" xmlns:xlink="&ns_xlink;" xmlns:a="http://ns.adobe.com/AdobeSV
^
openlogo.svg:22: namespace warning : xmlns: URI &ns_vars; is not absolute
<variableSets xmlns="&ns_vars;">
^
openlogo.svg:25: namespace warning : xmlns: URI &ns_custom; is not absolute
<v:sampleDataSets xmlns="&ns_custom;" xmlns:v="&ns_vars;"></v:sampleDataSet
^
openlogo.svg:28: namespace warning : xmlns: URI &ns_sfw; is not absolute
<sfw xmlns="&ns_sfw;">
^
Note that The Gimp seems to load the file just fine, although also
with an error message:
Execution error for procedure 'gimp-vectors-import-from-file':
Failed to import paths from 'openlogo.svg':
Error on line 17: Entity name 'ns_extend' is not known
Also, Iceweasel seems to load the file fine since it displays
correctly.
While I'm no expert in XML stuff, I see in the following lines at the
top of the file that the problems might relate to some Adobe-specific
namespace rules (or extensions, or whatever):
<?xml version="1.0" encoding="utf-8"?>
<!-- Generator: Adobe Illustrator 10.0, SVG Export Plug-In . SVG Version: 3.0.0 Build 77) -->
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.0//EN" "http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd"; [

<!ENTITY ns_extend "http://ns.adobe.com/Extensibility/1.0/";>
<!ENTITY ns_ai "http://ns.adobe.com/AdobeIllustrator/10.0/";>
<!ENTITY ns_graphs "http://ns.adobe.com/Graphs/1.0/";>

<!ENTITY ns_svg "http://www.w3.org/2000/svg";>
<!ENTITY ns_xlink "http://www.w3.org/1999/xlink";>
]>
Because opening the file in The Gimp transforms the svg graphics
object into a raster graphics object, the vector benefits of svg are
lost and thus The Gimp cannot be used as a substitute of Inkscape.
We may want to make sure that this file loads fine in Free Software
graphics svg-based programs and maybe convert it to either a more
generic svg file, or at least something free (Inkscape might be a good
candidate for this).
Any thoughts ?
Cheers,
Filippo
