Retrieve the legend graphic for a WMS layer

Usage

argentum_wms_legend(x, layer, style = NULL, format = "image/png")

Arguments

x: An organization name from argentum_organizations(), or a WMS URL.
layer: A single layer name.
style: Optional named style, or one per layer.
format: MIME type to request. NULL (default) negotiates one from the formats the service advertises for GetMap, preferring PNG, which keeps transparency. Pass a value such as "image/jpeg" to force it.

Value

A terra::SpatRaster holding the legend image (no CRS: it is a picture, not a map).
