Convert map to raster

Creates a raster image of map canvas content.

A map theme can be selected to render a predetermined set of layers with a defined style for each layer.

Alternatively, a single layer can be selected if no map theme is set.

If neither map theme nor layer is set, the current map content will be rendered. The minimum extent entered will internally be extended to be a multiple of the tile size.

Parameter

Label	Name	Type	Beschreibung
Minimum extent to render (xmin, xmax, ymin, ymax)	EXTENT	[extent]	Specify the extent of the output raster layer. One of: Use Canvas Extent Select Extent on Canvas Use Layer Extent… It will internally be extended to a multiple of the tile size.
Tile size	TILE_SIZE	[number] Default: 1024	Size of the tile of the output raster layer. Minimum value: 64.
Map units per pixel	MAP_UNITS_PER_PIXEL	[number] Default: 100.0	Pixel size (in map units). Minimum value: 0.0
Make background transparent	MAKE_BACKGROUND_TRANSPARENT	[boolean] Default: False	Allows exporting the map with a transparent background. Outputs an RGBA (instead of RGB) image if set to True.
Map theme to render Optional	MAP_THEME	[enumeration]	Use an existing map theme for the rendering.
Single layer to render Optional	LAYER	[enumeration]	Choose a single layer for the rendering
Output layer	OUTPUT	[raster] Default: Save to temporary file	Specification of the output raster. One of: Save to a Temporary File Save to File… The file encoding can also be changed here.

Create constant raster layer

Generates a raster layer where all pixels have the same value.

Parameter

Label	Name	Type	Beschreibung
Desired extent (xmin, xmax, ymin, ymax)	EXTENT	[extent]	Specify the extent of the output raster layer. One of: Use Canvas Extent Select Extent on Canvas Use Layer Extent… It will internally be extended to a multiple of the tile size.
Target CRS	TARGET_CRS	[crs] Default: Project CRS	CRS for the output raster layer
Pixel size	PIXEL_SIZE	[number] Default: 0.1	Pixel size (X=Y) in map units. Minimum value: 0.01
Constant value	NUMBER	[number] Default: 1	Constant pixel value for the output raster layer.
Constant	OUTPUT	[raster]	Specification of the output raster. One of: Save to a Temporary File Save to File… The file encoding can also be changed here.

Ausgaben

Label	Name	Type	Beschreibung
Constant	OUTPUT	[raster]	Raster covering the desired extent with the specified pixel size and value.

Set style for raster layer

Sets the style of a raster layer. The style must be defined as a QML file.

No new output are created: the QML style is assigned to the raster layer chosen.
