Multi level plugin for leaflet, the plugin define new methods for the Map object, a new control and new types of layers (L.layerName.ml
).
The plugin is been developed to visualize mutlislice maps for example created from bio images (confocal microscopy).
let map = L.map('map', {
multilevel: true,
levelControl: {
position: 'bottomleft'
}
});
let url = 'https://gherardovarando.github.io/leaflet-multilevel/demo/GAD67_tiles/slice{level}/{z}/{x}/{y}.png';
let mslayer = L.tileLayer.ml(url,{
minLevel: 1,
maxLevel: 43,
tileSize: L.point([88,256])
});
mslayer.addTo(map);
map.fitWorld();
map.setLevel(10);
To be able to use the TileLayer.ml
it is necessary to set the multilevel
option to true
in the map creation options or to add the multi level Handler.
Moreover the levelControl
option controls the presence and position of the slice control.
urlTemplate
a string of the following form'http://{s}.somedomain.com/{foo}/{level}/{z}/{x}/{y}.png'
options
as TileLayer options and moreover:maxLevel
minLevel
New methods for the map
object
-

-
Set the slice value to
l
if compatible with the limits.Returns
this
. -
Set the max slice value to
max
.Returns

this
.
The following events are fired by the map
object
-
Emitted when the user press down one of the arrow up/down key with the ctrl key.
-
Emitted when the user release the up/down arrow key and the slice value is increased or decreased. The event is not fired if the slice value is not changed (due to maxSlice, minSlice limits)
