This example uses a large SLD created on the client side to style a WMS
|
||||
layer. This example uses a WMS.Post layer which transfers data via the
|
||||
HTTP-POST protocol. <br>
|
||||
NOTE: Opera is not able to display transparent tiles with this layer,
|
||||
and in some Firefox browsers can appear ugly viewport-shaking effects
|
||||
while dragging arround. Use the 'unsupportedBrowsers' property to
|
||||
control which browsers should use plain image tiles (like Layer.WMS)
|
||||
instead. The default setting (["mozilla", "firefox", "opera"])
|
||||
excludes problematic browsers without removing the ability to use long
|
||||
request parameters, because all these browsers support long urls via
|
||||
GET.
