24.2.6. Vector conversion

24.2.6.1. Konwertuj format

Converts any OGR-supported vector layer into another OGR-supported format.

This algorithm is derived from the ogr2ogr utility.

Etykieta	Nazwa	Typ	Opis
Warstwa wejściowa	INPUT	[vector: any]	Input vector layer
Convert all layers from dataset	CONVERT_ALL_LAYERS	[wartość logiczna] Domyślnie: False	Converts the whole dataset. Supported output formats for this option are GPKG and GML.
Przekonwertowany	OUTPUT	[same as input]	Specification of the output vector layer. One of: Zapisz do pliku tymczasowego Zapisz do pliku… For Save to File, the output format has to be specified. All GDAL vector formats are supported. For Save to a Temporary File the QGIS default vector format will be used.

The algorithm id is displayed when you hover over the algorithm in the Processing Toolbox. The parameter dictionary provides the parameter NAMEs and values. See Using processing algorithms from the console for details on how to run processing algorithms from the Python console.

24.2.6.2. Rasterize (overwrite with attribute)

Overwrites a raster layer with values from a vector layer. New values are assigned based on the attribute value of the overlapping vector feature.

This algorithm is derived from the GDAL rasterize utility.

24.2.6.3. Rasterize (overwrite with fixed value)

Overwrites parts of a raster layer with a fixed value. The pixels to overwrite are chosen based on the supplied (overlapping) vector layer.

This algorithm is derived from the GDAL rasterize utility.

24.2.6.4. Rasterize (vector to raster)

Converts vector geometries (points, lines and polygons) into a raster image.

This algorithm is derived from the GDAL rasterize utility.

Etykieta	Nazwa	Typ	Opis
Warstwa wejściowa	INPUT	[vector: geometry]	Input vector layer
Field to use for a burn-in value Opcjonalne	FIELD	[tablefield: numeric]	Defines the attribute field from which the attributes for the pixels should be chosen

Burn value extracted from the „Z” values of the feature	USE_Z	[wartość logiczna] Domyślnie: False	Indicates that a burn value should be extracted from the „Z” values of the feature. Works with points and lines (linear interpolation along each segment). For polygons, works properly only if they are flat (same Z value for all vertices)
