Attributes

Attribute	Type	Default Value	Doc
layers	std::vector<xlf::layer>	{default_layer}	Vector of layers
controls	std::vector<xlf::control>	{}	Vector of controls
center	std::array<double, 2>	{0.0, 0.0}	Initial geographic center of the map
zoom	int	12	Initial map zoom level
max_zoom	int	18
min_zoom	int	1
dragging	bool	true	Whether the map be draggable with mouse/touch or not
touch_zoom	bool	true	Whether the map can be zoomed by touch-dragging with two fingers on mobile
scroll_wheel_zoom	bool	false	Whether the map can be zoomed by using the mouse wheel
double_click_zoom	bool	true	Whether the map can be zoomed in by double clicking on it and zoomed out by double clicking while holding shift
box_zoom	bool	true	Whether the map can be zoomed to a rectangular area specified by dragging the mouse while pressing the shift key
tap	bool	true	Enables mobile hacks for supporting instant taps
tap_tolerance	int	15	The max number of pixels a user can shift his finger during touch for it to be considered a valid tap
world_copy_jump	bool	false	With this option enabled, the map tracks when you pan to another “copy” of the world and seamlessly jumps to
close_popup_on_click	bool	true	Set it to false if you don’t want popups to close when user clicks the map
bounce_at_zoom_limits	bool	true	Set it to false if you don’t want the map to zoom beyond min/max zoom and then bounce back when pinch-zooming
keyboard	bool	true	Makes the map focusable and allows users to navigate the map with keyboard arrows and +/- keys
keyboard_pan_offset	int	80
keyboard_zoom_offset	int	1
inertia	bool	true	If enabled, panning of the map will have an inertia effect
inertia_deceleration	int	3000	The rate with which the inertial movement slows down, in pixels/second²
inertia_max_speed	int	1500	Max speed of the inertial movement, in pixels/second
zoom_control	bool	true
attribution_control	bool	true
zoom_animation_threshold	int	4
