[Gegl-developer] XML examples?

[Torsten Mohr <tmohr s netic de>]

Hello,

sorry if this is off-topic here, i want to use gegl as command-line with XML 
graphs to process images.

Googling for "gegl xml examples" i only found ONE example, i can't imagine 
that there isn't more available.

Or is there some general description on how to use the gegl operators in XML?

In the attached example (that works fine) it is not clear to me why first the 
blur is mentioned and then the load.  Is there documentation available about 
this?

<?xml version='1.0' encoding='UTF-8'?>
<gegl>
       <node operation='gegl:gaussian-blur'>
               <params>
                       <param name='std-dev-x'>0.999</param>
                       <param name='std-dev-y'>0.999</param>
               </params>
       </node>
       <node operation='gegl:load'>
               <params>
                       <param name='path'>../haus.png</param>
               </params>
       </node>
</gegl>


Thanks for any hints,
Torsten.
