Request

All Known Implementing Classes:

AbstractGetMapRequest, WMS1_0_0.GetMapRequest, WMS1_1_0.GetMapRequest, WMS1_1_1.GetMapRequest, WMS1_3_0.GetMapRequest
```
public interface GetMapRequest
extends Request
```
Construct a WMS getMap request.
Constructs a getMapRequest based on the following property values:
- ELEVATION
- TIME
- EXCEPTIONS
- BGCOLOR
- TRANSPARENT
- WIDTH
- HEIGHT
- SRS
- REQUEST
- LAYERS
- STYLES
- vendor specific parameters
Q: List availableFormats and availableExceptions - why are these here? It looks like they are designed to restrict the values used for SRS, format and exceptions. If so the code never uses them. Q: How constant is the GetMapRequest format across WMS versions? Do we need to generalize here?

  - addLayer
```
void addLayer(Layer layer,

    Parameters:
    
    layer - the Layer to use
    
    styleName - the style to use to draw the layer, can also be NULL, "" or "default"
  - addLayer

void addLayer(Layer layer)

    Adds a Layer to the list of layers to be requested. This layer will be drawn below any previously added layers. The style will be the default one.
    
    Parameters:
    
    layer - the Layer to use
  - setSRS
```
void setSRS(String srs)
```
    From the Web Map Service Implementation Specification: "The required SRS parameter states which Spatial Reference System applies to the values in the BBOX parameter. The value of the SRS parameter shall be on of the values defined in the character data section of an <SRS> element defined or inherited by the requested layer. The same SRS applies to all layers in a single request. If the WMS has declared SRS=NONE for a Layer, then the Layer does not have a well-defined spatial reference system and should not be shown in conjunction with other layers. The client shall specify SRS as "none" in the GetMap request and the Server may issue a Service Exception otherwise."
    
    Parameters:
    
    srs - A String indicating the Spatial Reference System to render the layers in.
  - setBBox
```
void setBBox(String bbox)
```
    From the Web Map Service Implementation Specification: "The required BBOX parameter allows a Client to request a particular Bounding Box. The value of the BBOX parameter in a GetMap request is a list of comma-separated numbers of the form "minx,miny,maxx,maxy". If the WMS server has declared that a Layer is not subsettable, then the Client shall specify exactly the declared Bounding Box values in the GetMap request and the Server may issue a Service Exception otherwise."
    NOTE: In WMS 1.3.0, the specification of "EPSG:4326" has the axis swapped, so a request made in 1.1.1 using "minx,miny,maxx,maxy" would use "miny,minx,maxy,maxx" in 1.3.0. Only when using EPSG:4326!
    Currently it is up to the client to do this on there own. TODO Accept Envelopes and doubles instead of Strings, and perform the 1.3.0 conversion automatically. Also note that not all servers may implement this. Should provide an option to use 1.1.1 format even when using 1.3.0.
    
    Parameters:
    
    bbox - A string representing a bounding box in the format "minx,miny,maxx,maxy"
  - setBBox
```
void setBBox(Bounds box)
```
    Sets the BBOX and SRS information from the provided Envelope (such as a CRSEnvelope).
  - setFormat
```
void setFormat(String format)
```
    From the Web Map Service Implementation Specification: "The required FORMAT parameter states the desired format of the response to an operation. Supported values for a GetMap request on a WMS instance are listed in one or more <Format> elements in the &;ltRequest><GetMap> element of its Capabilities XML. The entire MIME type string in <Format> is used as the value of the FORMAT parameter."
    
    Parameters:
    
    format - The desired format for the GetMap response
  - setDimensions
```
void setDimensions(String width,
                   String height)
```
    From the Web Map Service Implementation Specification: "The required WIDTH and HEIGHT parameters specify the size in integer pixels of the map image to be produced. WIDTH specifies the number of pixels to be used between the minimum and maximum X values (inclusive) in the BBOX parameter, while HEIGHT specifies the number of pixels between the minimum and maximum Y values. If the WMS server has declared that a Layer has fixed width and height, then the Client shall specify exactly those WIDTH and HEIGHT values in the GetMap request and the Server may issue a Service Exception otherwise."
  - setDimensions
```
void setDimensions(int width,
                   int height)
```
  - setDimensions
```
void setDimensions(Dimension imageDimension)
```
  - setTransparent
```
void setTransparent(boolean transparent)
```
    From the Web Map Service Implementation Specification: "The optional TRANSPARENT parameter specifies whether the map background is to be made transparent or not. The default value is false if the parameter is absent from the request."
    
    Parameters:
    
    transparent - true for transparency, false otherwise
  - setBGColour
```
void setBGColour(String bgColour)
```
    Specifies the colour, in hexidecimal format, to be used as the background of the map. It is a String representing RGB values in hexidecimal format, prefixed by "0x". The format is: 0xRRGGBB. The default value is 0xFFFFFF (white)
    
    Parameters:
    
    bgColour - the background colour of the map, in the format 0xRRGGBB
  - setExceptions
```
void setExceptions(String exceptions)
```
    The exceptions type specifies what format the server should return exceptions in.
    Valid values are:
    
    "application/vnd.ogc.se_xml" (the default)
    "application/vnd.ogc.se_inimage"
    "application/vnd.ogc.se_blank"
  - setTime
```
void setTime(String time)
```
    See the Web Map Server Implementation Specification 1.1.1, Annexes B and C
    
    Parameters:
    
    time - See the Web Map Server Implementation Specification 1.1.1, Annexes B and C
  - setElevation
```
void setElevation(String elevation)
```
    See the Web Map Server Implementation Specification 1.1.1, Annex C, in particular section C.4
    
    Parameters:
    
    elevation - See the Web Map Server Implementation Specification 1.1.1, Annex C
  - setSampleDimensionValue
```
void setSampleDimensionValue(String name,
                             String value)
```
    See the Web Map Server Implementation Specification 1.1.1, Annex C, in particular section C.4.2
    Example use: request.setSampleDimensionValue("DIM_WAVELENGTH", "4000");
    
    Parameters:
    
    name - the request parameter name to set (usually with 'dim_' as prefix)
    
    value - the value of the request parameter (value, interval or comma-separated list)
  - setVendorSpecificParameter
```
void setVendorSpecificParameter(String name,
                                String value)
```
    Used to implement vendor specific parameters. Entirely optional.
    
    Parameters:
    
    name - a request parameter name
    
    value - a value to accompany the name
  - setProperties
```
