Say I have a shapefile with 20 graduated classes that I'm using in QGIS. I want to save the layer style so that I can use it on other shapefiles, but I can't edit the layer transparency without editing each class (20) individually.
Is it possible to edit the layer transparency in a .sld or .qml file? I arbitrarily set the transparency of one class to 53% and another to 78% (just for the sake of testing), saved both a .sld and a .qml, but I couldn't find these values anywhere in the two files. I also searched for things like 'opacity' and 'transparency' but I don't see an indication of how this is saved. However, my changes (of 53% and 78%) are reflected when loading a .qml file with the shapefiles.
It's not the end of the world to have to edit each class individually at first if the changes are reflected after saving a .qml. But I would still prefer something more reproducible since this would be really easy to do with a simple find/replace, and I may have to change the transparency of all classes at various times in the future.
