Re: [Rdkit-discuss] svg differences and rendering in Browser

[hari j. <ha...@gm...>]

Thanks to Vasiliy Faronov on Stack Overflow, I was able to understand whats
going on.

It seems that on OSX the version of cairo I have with RDKIT from
head(69cf6af68554e83) produces xhtm-ized svg.

On Ubuntu the cairo produces de-xhtml-ized svg.

De-xhtml-ized svg

<svg xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink" width="300pt"
height="300pt" viewBox="0 0 300 300" version="1.1"><defs><g><symbol
overflow="visible" id="glyph0-0"><path style="stroke:none;" d="M
0.40625 1.421875 L 0.40625 -5.640625 L 4.40625 -5.640625 L 4.40625

xhtml-ized-svg


<svg:svg version="1.1" baseProfile="full"
        xmlns:svg="http://www.w3.org/2000/svg"
        xmlns:xlink="http://www.w3.org/1999/xlink"
        xml:space="preserve" width="300px" height="300px" ><svg:line
x1="114.41" y1="132.42" x2="130.03" y2="146.44" stroke="rgb(0,0,0)"
stroke-width="1"></svg:line><svg:line x1="113.56" y1="136.50"
x2="126.06" y2="147.72" stroke="rgb(0,0,0)"
stroke-width="1"></svg:line>
<svg:line x1="87.26" y1="137.68" x2="96.45"

Since I am trying to use the svg inline with an html document with
content-type:text/html
The browsers were not able to handle the namespace switching required.

Vasiliy suggested a hack or an elegant switch with an xml library.

svg_string = svg_string.replace(u'svg:', u'').replace(u'xmlns:svg', u'xmlns')


I will have to handle the namespace change externally in my code.


Thanks
Hari
