new VTileLayer(url, optionsopt) → {VTileLayer}

Parameters

• url string

  URL of the tile server

• options object <optional>
  

  Options.

  Properties

  • title string <optional>
    <nullable>
    null

    Layer title. Defaults to the image filename with extension removed followed by the OBJECT name if available.

  • setTitleBar boolean <optional>
    false

    Update the document / webpage title using the layer title.

  • crs leaflet.CRS | WCS <optional>
    <nullable>

    null

    World coordinates (either in RA,Dec decimal form or in hh:mm:ss.s±dd:mm:ss.s sexagesimal format), or any Sesame-compliant identifier defining the initial centering of the map upon layer initialization. Sexagesimal coordinates and identifier strings are sent to the Sesame resolver service for conversion to decimal coordinates. Assume x,y pixel coordinates if WCS information is missing. Defaults to image center.

  • fov number <optional>
    <nullable>
    null

    Field of View (FoV) covered by the map upon later initialization, in world coordinates (degrees, or pixel coordinates if WCS information is missing). Defaults to the full FoV.

  • minZoom number <optional>
    0

    Minimum zoom factor.

  • maxZoom number <nullable>
    

    Maximum zoom factor.

  • maxNativeZoom number <optional>
    18

    Maximum native zoom factor (including resampling).

  • noWrap boolean <optional>
    true

    Deactivate layer wrapping.

  • brightness number

    Brightness level.

  • contrast number

    Contrast factor.

  • colorSaturation number

    Color saturation for multi-channel data (0.0: B&W, >1.0: enhance).

  • gamma number

    Display gamma.

  • cMap string <optional>
    'grey'

    Colormap for single channels or channel combinations. Valid colormaps are 'grey', 'jet', 'cold' and 'hot'.

  • invertCMap boolean <optional>
    false

    Invert Colormap or color mix (like a negative).

  • quality number

    JPEG encoding quality in percent.

  • mixingMode string <optional>
    'color'

    Channel mixing mode. Valid modes are 'mono' (single-channel) and 'color'.

  • channelColors Array.<RGB> <optional>
    []

    RGB contribution of each channel to the mixing matrix. Defaults to rgb(0.,0.,1.), rgb(0.,1.,0.), rgb(1.,0.,0.), rgb(0.,0.,0.), ...]

  • channelLabels Array.<string> <optional>
    []

    Channel labels. Defaults to ['Channel #1', 'Channel #2', ...].

  • channelLabelMatch string <optional>
    '.*'

    Regular expression matching the labels of channels that are given a color by default.

  • channelUnits Array.<string> <optional>
    []

    Channel units. Defaults to ['ADU','ADU',...].

  • minMaxValues Array.<Array.<number>> <optional>
    []

    Pairs of lower, higher clipping limits for every channel. Defaults to values extracted from the data header if available or [[0.,255.], [0.,255.], ...] otherwise.

  • channel number <optional>
    0

    Default active channel index in mono-channel mixing mode.

  • framerate number

    Default animation framerate.

  • sesameURL string <optional>
    'https://cdsweb.u-strasbg.fr/cgi-bin/nph-sesame'

    URL of the Sesame resolver service.

  • credentials string <optional>
    <nullable>
    null

    For future use.

Returns

• VTileLayer

  VisiOmatic TileLayer instance.

Example

const map = L.map('map'),
      url = '/tiles?FIF=example.fits',
      layer = new VTileLayer(url, {cmap: 'jet'}); 
layer.addTo(map);
