    • setSRS

      public 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."
      Specified by:
      setSRS in interface GetMapRequest
      Parameters:
      srs - A String indicating the Spatial Reference System to render the layers in.

    • setBBox

      public 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."

      Yu must also call setSRS to provide the spatial reference system information (or CRS:84 will be assumed)

      Specified by:
      setBBox in interface GetMapRequest
      Parameters:
      bbox - A string representing a bounding box in the format "minx,miny,maxx,maxy"

    • setFormat

      public 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."
      Specified by:
      setFormat in interface GetMapRequest
      Parameters:
      format - The desired format for the GetMap response

    • setDimensions

      public 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."
