Bug 18985 – [QT][CAIRO] x- and y-attributes of <use>-element not used

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: SVG

[Dirk Schulze]

If I understood the code right, the <use>-element is transformed to a <g>-element (in a basic case). 
All Attributes are given to the transformed element (like transform,fill,stroke), except for the x- and y-attributes. This only affects the Qt- and Cairo-implementation.

a simple problem:
http://trac.webkit.org/browser/trunk/WebCore/svg/SVGUseElement.cpp#L323
I get a comma instead of a point for floating-point (non-english-speaker), thats why webkit ignores the transformation.

e.g.:

transform(12,000, 30,500) instead of
transform(12.000, 30.500)

(In reply to comment #1)
I use gcc (GCC) 4.2.3

Looks like vsnprintf is locale-aware, which is probably not what we want inside WebCore.

A solution could be

setlocale(LC_NUMERIC, "C");

add the line before a vsnprintf() operation or system wide (don't know it this is possible) and it should work. (perhaps with #include <local.h>)
I tested it in SVGUseElement.cpp with success.

I think the code should not use String::format() but simply toDouble() on a constructed string and construct the entire string to parse manually. String::toDouble() is locale-unaware as far as I can see.
