layer_spatial.SpatRaster.Rd
This is intended for use with RGB(A) rasters (e.g., georeferenced imagery or photos). To work with bands as if they were columns, use df_spatial and geom_raster.

A SpatRaster object created with terra::rast()
.
Currently, only RGB or RGBA rasters are supported. In the future, one may be able to map specific bands to the fill and alpha aesthetics.
Interpolate resampling for rendered raster image
Lets raster exist without modifying scales
Delay projection and resample of raster until the plot is being rendered
if lazy = TRUE, the dpi to which the raster should be resampled
