Re: Converting SVG to Image - SVG format problems

[Vincent Hardy <vh...@eng.sun.com>]

Alexandre,

I think the SVG is invalid because the rgb() functions are missing
commas between the r/g and g/b values. For example, it uses 
rgb(51 204 255) instead of rgb(51,204,255). From the CSS2 spec:

"The format of an RGB value in the functional notation is ’rgb(’
followed by a
comma-separated list of three numerical values (either three integer
values or
^^^^^^^^^^^^^^^
three percentage values) followed by ’)’."

So my take is that there is a problem with the tool that generates the 
SVG.

I hope this helps.
Vincent.
