Map component: minimap — tm

Map component that adds a minimap in view mode.

Usage

tm_minimap(server, toggle, stack, position, group_id, z, ...)

Arguments

server

name of the provider or an URL (see tm_tiles). By default, it shows the same map as the basemap, and moreover, it will automatically change when the user switches basemaps. Note the latter does not happen when server is specified.

toggle

should the minimap have a button to minimise it? By default TRUE.

stack

stack with other map components, either "vertical" or "horizontal".

position

The position specification of the component: an object created with tm_pos_in() or tm_pos_out(). Or, as a shortcut, a vector of two values, specifying the x and y coordinates. The first is "left", "center" or "right" (or upper case, meaning tighter to the map frame), the second "top", "center" or "bottom". Numeric values are also supported, where 0, 0 means left bottom and 1, 1 right top. See also vignette about positioning. In case multiple components should be combined (stacked), use group_id and specify component in tm_comp_group().

group_id

Component group id name. All components (e.g. legends, titles, etc) with the same group_id will be grouped. The specifications of how they are placed (e.g. stacking, margins etc.) are determined in tm_comp_group() where its argument id should correspond to group_id.

z

z index, e.g. the place of the component relative to the other componets

Arguments passed on to leaflet::addMiniMap

map: a map widget object
width: The width of the minimap in pixels. Defaults to 150.
height: The height of the minimap in pixels. Defaults to 150.
collapsedWidth: The width of the toggle marker and the minimap when collapsed, in pixels. Defaults to 19.
collapsedHeight: The height of the toggle marker and the minimap when collapsed, in pixels. Defaults to 19.
zoomLevelOffset: The offset applied to the zoom in the minimap compared to the zoom of the main map. Can be positive or negative, defaults to -5.
zoomLevelFixed: Overrides the offset to apply a fixed zoom level to the minimap regardless of the main map zoom. Set it to any valid zoom level, if unset zoomLevelOffset is used instead.
centerFixed: Applies a fixed position to the minimap regardless of the main map's view / position. Prevents panning the minimap, but does allow zooming (both in the minimap and the main map). If the minimap is zoomed, it will always zoom around the centerFixed point. You can pass in a LatLng-equivalent object. Defaults to false.
zoomAnimation: Sets whether the minimap should have an animated zoom. (Will cause it to lag a bit after the movement of the main map.) Defaults to false.
toggleDisplay: Sets whether the minimap should have a button to minimise it. Defaults to false.
autoToggleDisplay: Sets whether the minimap should hide automatically, if the parent map bounds does not fit within the minimap bounds. Especially useful when 'zoomLevelFixed' is set.
minimized: Sets whether the minimap should start in a minimized position.
aimingRectOptions: Sets the style of the aiming rectangle by passing in a Path.Options (https://web.archive.org/web/20220702182250/https://leafletjs.com/reference-1.3.4.html#path-options) object. (Clickable will always be overridden and set to false.)
shadowRectOptions: Sets the style of the aiming shadow rectangle by passing in a Path.Options (https://web.archive.org/web/20220702182250/https://leafletjs.com/reference-1.3.4.html#path-option) object. (Clickable will always be overridden and set to false.)
strings: Overrides the default strings allowing for translation.
tiles: URL for tiles or one of the pre-defined providers.
mapOptions: Sets Leaflet options for the MiniMap map. It does not override the MiniMap default map options but extends them.
