This algorithm modifies the type of a given attribute in a vector layer, converting a text attribute containing numeric strings into a numeric attribute.
qgis:tilesxyz: >
This algorithm generates raster XYZ tiles of map canvas content.
Tile images can be saved as individual images in directory structure, or as single file in MBTiles format.
Tile size is fixed to 256x256.
qgis:topologicalcoloring: >
This algorithm assigns a color index to polygon features in such a way that no adjacent polygons share the same color index, whilst minimizing the number of colors required.
