Attributes |
Description |
|
background-color |
The background color in the WMS request, as a comma separated string of red, green, blue
values, example "255,0,0". Transformed to the BGCOLOR parameter when making the request.
Optional, no BGCOLOR parameter is used if this attribute is not used.
|
|
exception-format |
The exception format that is returned from the WMS service in the event of
errors. The format must match one of the exception formats supported by the
server, so check the capabilities response for valid values. Formats that
return XML are best, so use "WMS_XML" or "application/vnd.ogc.se_xml"
if possible. Required.
|
|
format |
The format of the image returned from the WMS service. The format must
match one of the formats supported by the server, so check the capabilities
response for valid values. If possible, use a format that supports
transparencies, which are "PNG", GIF", "image/png" or "image/gif". Required.
|
|
href |
The URL used for requesting map images. The map request arguments will be
added to the value when making the requests, so only include the base URL as
specified in the capabilities file. Note that if your URL contains ampersands,
they must be escaped like "&" in the XML. Required.
|
|
sld |
The sld attribute is used with Styled Layer Descriptor capable WMS services
to specify alternate symbolization for layers. If you wish to use SLD
symbolization, this attribute should contain the URL of the XML file that
contains the styling. Optional.
|
|
transparent |
An indicator of whether the map should be requested with transparency where there is no data.
Usually, WMS images are requested with TRANSPARENT=TRUE, but you can use this setting to
ensure that the request will be done with TRANSPARENT=FALSE. Usually, it is best to not use
this attribute and let IMF decide what to do. Optional.
