An image that is repeated below all features on a map as a background.
srs¶

Default Value: +proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs (The proj4 literal of EPSG:4326 is assumed to be the Map’s spatial reference and all data from layers within this map will be plotted using this coordinate system. If any layers do not declare an srs value then they will be assumed to be in the same srs as the Map and not transformations will be needed to plot them in the Map’s coordinate space)

Grain merge adds the two layers together and subtracts 128 from the value, making the resulting area sometimes high-contrast. Screen often gives a lighter, washed-out appearance. Multiply multiplies the pixels, giving a high-contrast result. Divide divides the upper layer by the lower layer, making a lighter version.

Possible values: fast
bilinear
bilinear8
bicubic
spline16

lanczos
Default Value: fast
The scaling algorithm used to making different resolution versions of this raster layer. Bilinear is a good compromise between speed and accuracy, while lanczos gives the highest quality.

Type: integer
Default Value: 16 (Reprojection mesh will be 1/16 of the resolution of the source image)
A reduced resolution mesh is used for raster reprojection, and the total image size is divided by the mesh-size to determine the quality of that mesh. Values for mesh-size larger than the default will result in faster reprojection but might lead to distortion.
