Move a rendered map's view — arc

arc_goto() animates the view, unlike set_view() on a proxy, which jumps to the new position. arc_screenshot() captures the view as a PNG data URL and sends it back as input$<output_id>$screenshot.

Usage

arc_goto(proxy, center = NULL, zoom = NULL, extent = NULL, duration = NULL)

arc_screenshot(proxy, format = "png")

Arguments

proxy: Defines which arc_map_proxy() to act on.
center: default NULL. Defines the target centre as c(lon, lat).
zoom: default NULL. Defines the target zoom level.
extent: default NULL. Defines the target extent, overriding center and zoom.
duration: default NULL. Defines the animation length in milliseconds.
format: default "png". Defines the screenshot format, "png" or "jpg".

Value

proxy, invisibly.

Examples

if (interactive()) {
  arc_map_proxy("map") |>
    arc_goto(center = c(-79, 35.5), zoom = 8)
}
