Project: QGIS
Version: 3.4 LTR
This new algorithm sets a vector layer's renderer to a categorized renderer using matching symbols from a style database.
A specified expression (or field name) is used to create categories for the renderer, with QGIS creating a category for each unique value within the layer. Each category is individually matched to the symbols which exist within the specified QGIS XML style database. Whenever a matching symbol name is found, the category's symbol will be set to this matched symbol.
The matching is case-insensitive by default, but can be made case-sensitive if required. Optionally, non-alphanumeric characters in both the category value and symbol name can be ignored while performing the match. This allows for greater tolerance when matching categories to symbols.
If desired, tables can also be output containing lists of the categories which could not be matched to symbols, and symbols which were not matched to categories.
