\arguments{
\item{handleable}{A geometry vector (e.g., \code{\link[wk:wkb]{wkb()}}, \code{\link[wk:wkt]{wkt()}}, \code{\link[wk:xy]{xy()}},
\code{\link[wk:rct]{rct()}}, or \code{\link[sf:sfc]{sf::st_sfc()}}) for which \code{\link[wk:wk_handle]{wk_handle()}} is defined.}
\item{handler}{A \link[wk:wk_handle]{wk_handler} object.}
\item{...}{Passed to the \code{\link[wk:wk_handle]{wk_handle()}} method.}
\item{oriented}{TRUE if polygon ring directions are known to be correct
(i.e., exterior rings are defined counter clockwise and interior
rings are defined clockwise).}
\item{check}{Use \code{check = FALSE} to skip error on invalid geometries}
\item{projection, s2_projection}{One of \code{\link[=s2_projection_plate_carree]{s2_projection_plate_carree()}} or
\code{\link[=s2_projection_mercator]{s2_projection_mercator()}}}
\item{tessellate_tol, s2_tessellate_tol}{An angle in radians.
Points will not be added if a line segment is within this
distance of a point.}
\item{x_scale}{The maximum x value of the projection}
\item{centre}{The center point of the orthographic projection}
\item{epsilon_east_west, epsilon_north_south}{Use a positive number to
define the edges of a Cartesian world slightly inward from -180, -90,
180, 90. This may be used to define a world outline for a projection where
projecting at the extreme edges of the earth results in a non-finite value.}
}
\value{
\itemize{
\item \code{s2_projection_plate_carree()}, \code{s2_projection_mercator()}: An external pointer
to an S2 projection.
