Convert a layer to a raster
This filter simply converts the given layer, grob, or ggplot to a raster and
inserts it back again. It is useful for vector graphics devices such as
svglite if a layer contains a huge amount of primitives that would make the
file slow to render. as_reference(x, id) is a shorthand for
with_raster(x, id = id, include = FALSE) that makes the intent of using
this grob or layer as only a filter reference clear.
with_raster(x, ...)
x |
A ggplot2 layer object, a ggplot, a grob, or a character string naming a filter |

Arguments to be passed on to methods. See the documentation of supported object for a description of object specific arguments. |
Depending on the input, either a grob, Layer, list of Layers,
guide, or element object. Assume the output can be used in the same
context as the input.
