Re: Generating SVG from Python

Anybody see an reason (licensing, other) why we should not use this:

in Gump? [I found nothing else via Google. I also looked on python.org
(including in the package index) and in ASPN cookbook.]
 

The license seems OK for me (see below)

I'd like to use it to generate some SVG images. I believe that some browsers
can render [right term?] them raw (IE just seemed to, albeit slowly), but I
also believe that Forrest uses Batik to generate PNG (I assume for browser
portability). Again, I'll try to make this optional, so folks don't have to
give up the cycles if they don't wish to.
 

I am a SVG fan, so +1.
If somebody is interested, I know how to install the Adobe SVG Plugin in 
FireFox on Windows
(not easy, I found some information about this at different places on 
mozilla forums).

I'd like to start simple (perhaps generate some slider type images to show
FOG values, etc.) Eventually I'd like to draw some graphs representing
dependency tress, etc.
Any feedback? Any objections?

 

No Objection !

Cheers, :-)

Here a programming example from the same source file :

   d=drawing()
   #then you create a SVG root element
   s=svg()
   #then you add some elements eg a circle and add it to the svg root 
element
   c=circle()
   #you can supply attributes by using named arguments.
   c=circle(fill='red',stroke='blue')
   #or by updating the attributes attribute:
   c.attributes['stroke-width']=1
   s.addElement(c)
   #then you add the svg root element to the drawing
   d.setSVG(s)
   #and finaly you xmlify the drawing
   d.toXml()
