Hi all,

We have a (generated) qml style with 1500 rules (all different fill images!).

Using that style is a PITA, slowing QGIS down very much.

After the style is loaded, around 90% of the style rules are not used (I think).

So my idea was to either clean up the rules after the loading (which already 
takes a long time).
OR use some python code to first find the distinct values (styles are simple: 
just one code), and then load the qml and only apply/select those rules 
needed...
OR something like: use categorical styling but take the symbols from this qml 
???

Anybod a clever idea for this?
Or maybe some plugin?

Regards,

Richard Duivenvoorde
