[Qgis-developer] Re: SLD export : improve plugin or wait for feature ?

[Marco Hugentobler]

Hi Kimaidou

The QgsSLDParser in the mapservercode transforms SLD->QGIS symbology (not the 
other way round). The code is a bit old and it does not handle the new 
symbology. So I think it would be good to rewrite the SLD conversion 
completely based on symbology-ng.

Yes, for maximum reusability, it should be in C++ and in the core library. 
Like this, it can be used by desktop, mapserver and plugins. Import from SLD 
could be done based on the rule based renderer class, which has a similar 
organisation as SLD.

Regards,
Marco
