Labeling a feature
Once your map layers are styled, the next step to creating a complete map is labeling features. We'll explore the basics of labeling in this recipe.
Getting ready
Download the following zipped shapefile from https://github.com/GeospatialPython/Learn/raw/master/MSCities_Geo_Pts.zip.
Extract the shapefile to a directory named ms
in your qgis_data
directory.
How to do it...
We will load the point shapefile layer, create a label object, set its properties, apply it to the layer, and then add the layer to the map. To do this, we need to perform the following steps:
- First, to save space, we'll specify the path to the shapefile:
src = "/qgis_data/ms/MSCities_Geo_Pts.shp"
- Next, we'll load the layer:
lyr = QgsVectorLayer(src, "Cities", "ogr")
- Then, we'll create the labeling object:
label = QgsPalLayerSettings()
- Now, we'll configure the labels, starting with the current layer settings being read:
