Vector to raster (complete interface)

:guilabel:`Vector to raster`

This tab allows for the conversion of a vector (polygon) to raster format. It is loaded only if the :guilabel:`Simplified interface` is not enabled.

Convert vector to raster

Tool symbol and name	Description
:guilabel:`Select the vector`	select a vector already loaded in QGIS
	refresh layer list
:guilabel:`Use the value field of the vector`	if checked, the selected field is used as attribute for the conversion; pixels of the output raster have the same values as the vector attribute
:guilabel:`Use constant value`	if checked, the polygons are converted to raster using the selected constant value
:guilabel:`Select the reference raster`	select a reference raster; pixels of the output raster have the same size and alignment as the reference raster
	refresh layer list
:guilabel:`Pixel size`	set the size of pixel of output raster
:guilabel:`Minimum extent`	if checked, the output raster has the minimum vector extent; otherwise, output extent is the same as the :guilabel:`Select the reference raster`
:guilabel:`Select the type of conversion`	select the type of conversion among: :guilabel:`pixel_center`: during the conversion, vector is compared to the reference raster; output raster pixels are attributed to a polygon if pixel center is within that polygon :guilabel:`all_touched`: during the conversion, vector is compared to the reference raster; output raster pixels are attributed to a polygon if pixel touches that polygon :guilabel:`area_based`: during the conversion, output raster pixels are attributed based on area proportion of polygons
:guilabel:`Area precision`	for :guilabel:`area_based` method, the higher the value, the higher is the precision in the calculation of area proportion (and the time required for calculation)
:guilabel:`Use value as NoData`	if checked, set a value for NoData pixels
:guilabel:`Script`	add this function to the :ref:`script_tab`
:guilabel:`RUN`	run this function
