New processing algorithm - copying only certain features to a new shp file using QGIS
I have a point layer (miejsowosci_lubelskie.shp) with cities.
This layer has a "Pow" field containing the numerical value of the city area. The smallest city has an area of "9" and the largest "235".
The algorithm is to have parameters:
Input parameters:
WEKTOR - in this parameter the default value is to be layer "miejscowosci_lubelskie.shp"
POLE - in this parameter the default value is to be the "Pow" field from the layer "miejscowosci_lubelskie.shp"
WARTOSC - in this parameter the default value is 100
Output parameters:
WYNIK - the resulting vector layer with the default name "output_layer.shp"
The result of this algorithm is to be the output layer (output_layer.shp), which only has cities with an area less than or equal to 100.
I need help writing a processing script (algorithm) in .py format, so that I can open this algorithm in QGIS.
