It can take several one-layer parameters (so, in the end, there is a fixed number of them), or take a multiple-layer parameter, which is a single parameter but the user can select a list with an undetermined number of layers (even an empty list, if allowed) > > 2.

The multiple input can have several layer types at once, but single layers can't > > 3. Must a Processing plugin output a layer? No. It can output layers, tables, numbers, string...in any combination you want, just like input parameters Hope this helps _______________________________________________ Qgis-developer mailing list [email protected] List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
