Creates a WMS image model.
Optional
options: WMSImageModelConstructorOptionsthe options for the WMSImageModel.
ProgrammingError if any of the following cases occurs:
reference
and bounds
in the options
are both passed and the references do not
match.
sld
and sldBody
are specified in the options.The background color the WMS server must use when generating the WMS image. Note that this option is only considered by the server when the WMSImageModel.transparent property is false. The backgroundColor is a string that must be formatted as "0xRRGGBB", where RGB values are represented as hexadecimal values. If you try to assign a string that does not adhere to this format an exception will be thrown.
The coordinate type of geometries in this model
Indicates whether or not credentials should be included with HTTP requests.
See GoogleImageModel.credentials for more information.
The default value is false
.
Dimension parameters to send along with WMS GetMap
and GetFeatureInfo
request.
Typical dimensions are TIME
and ELEVATION
.
The object literal can contain simple key/value pairs. Dimension names will be prefixed with "DIM_" in the
WMS requests, if this is not already the case. The dimension names TIME
and ELEVATION
will never be prefixed. Accepted values are strings, numbers, booleans.
A ProgrammingError will be thrown if values of another type are used.
Values must not be URL encoded. Assigning other values than object literals to dimensions
will
throw a ProgrammingError.
Assigning to this property will automatically trigger a refresh of the visualization on the map.
The example below configures a WMSImageModel to request temperature data on the 1st of july 2016, at ground level.
wmsImageModel.dimensions = {
TIME: "2016-07-01T12:00:00.000Z",
ELEVATION: 0
};

The WMS layers, specified as an array of strings. Each string is a layer name identifier.
These layers are not the same as a Layer. They are the layers exposed by the WMS server and which are listed in the capabilities document of the WMS server.
This layers array must be considered as an immutable property. This means that to add or to remove layers, you will need to reassign this property again. Directly removing elements from the array, or directly adding elements to the array, without resetting the property will have no effect.
The order of the layers in the array corresponds to the rendering order of the layers by the WMS server.
Assigning to this property will automatically trigger a refresh of the visualization on the map.

An object containing metadata about this model
The WMS layers that will be queried. These are the layers that will be used in the GetFeatureInfo
requests performed by the WMSImageLayer.getFeatureInfo method.
The query layers are specified as an array of strings. Each string is a layer name identifier.
This queryLayers array must be considered as an immutable property. This means that to add or to remove layers, you will need to reassign this property again. Directly removing elements from the array, or directly adding elements to the array, without resetting the property will have no effect.
Assigning to this property will automatically trigger a refresh of the visualization on the map.
Reports whether this model supports GetFeatureInfo requests. This is only true if the queryLayers property is filled in.
The reference in which this model is defined
Headers to send with every HTTP request.
See GoogleImageModel.requestHeaders for more information.
The default value is null
.
Custom request parameters to send along with WMS GetMap
and GetFeatureInfo
request.
The object literal can contain simple key/value pairs. If you try to configure request parameters that
are part of the WMS standard, a ProgrammingError will be thrown. For
example, adding a "layers" request parameter is not allowed. Accepted values are strings, numbers and booleans.
A ProgrammingError will be thrown if values of another type are used.
Values must not be URL encoded.
Assignments of other values than object literals to requestParameters
will throw an Error. Clearing
the parameters can be done by assigning null
or an empty object literal to
requestParameters
. Assigning to this property will automatically trigger a refresh of the
visualization on the map.
2016.1
A url to a Styled Layer Descriptor that must be passed when making a request. This corresponds to the SLD request parameter in the GetMap request. If you assign to this value, the value of the sldBody property, if any, will be reset to null.
Assigning to this property will automatically trigger a refresh of the visualization on the map.
2016.1
the Styled Layer Descriptor to pass when making a request. This corresponds to the SLD_BODY
request parameter in the GetMap
request. The SLD must not be URL encoded.
If you assign to this value, the value of the sldBody property, if any, will be reset to null.
Assigning to this property will automatically trigger a refresh of the visualization on the map.
2016.1
The named styles to apply on the server when making a request. The style names in the array apply to the
respective layers. Specifying a style name for a layer is
optional; if you do not wish to specify a style name for a particular layer, you can omit the entry for that
layer or pass an empty string in the styles
array. The STYLES
request parameter is
mandatory in a WMS request, but can be empty in case no styles
are defined.
Assigning to this property will automatically trigger a refresh of the visualization on the map.
2016.1
Indicates whether the ImageModel will request transparent tiles from the server or not
Signals that the underlying data for the tiled images has changed. If this model is added to a map using a RasterImageLayer, calling this method will thus trigger a refresh of the visualization.

A
RasterImageModel
that can access an OGC WMS Server. Use this model instead of the WMSTileSetModel if you want to visualize WMS images at an arbitrary scale and with arbitrary extents. For example, if the WMS images contain text, the text may appear smaller on the map than intended when using aWMSTileSetModel
. You can avoid this by using thisWMSImageModel
instead.Typically, you don't need to call the constructor yourself. Instead, use the factory methods createFromURL or createFromCapabilities to create an instance of this model. The following example demonstrates how to set up a
WMSImageModel
to retrieve WMS image data for a given service url and layer name:If you want to access the WMS server's capabilities and explore the service metadata and available data sets, you first have to create a WMSCapabilities instance. This instance can also be to create a
WMSImageModel
afterwards:Limitations
The limitations for single-image rasters also apply to this model, cf. RasterImageLayer. Most notably, WebGLMap does not support single-image raster models and layers.
Supported versions
LuciadRIA supports consuming WMS services that support version 1.1.1 and 1.3.0 of the OGC WMS specification.
