Developer’s Corner: GeoServer Stunning image quality + max compression rate = New PNG8 quantizer is served!

Blog ‐ Posted on 09.05.2012 by simone giannecchini

Hi everybody,in this blog we want to introduce the new GeoServer PNG8 quantizer.PNG8 is a shorthand for PNG 8bit, that is, a PNG image that uses a fixed palette of 256 (or less) colors and can thus encode each pixel with just one byte.The interest in the format comes from its smaller size, often between 2 and 3 times smaller than the equivalent 24bit PNG image.

Such standard defines an interactive protocol that takes full advantage of JPEG 2000’s scalability properties by means of additional signaling JPIP in order to interactively deliver pieces of a JPEG 2000 image in essentially arbitrary order, in response to real-time application requests using potential very low...

Dynamic WMS styling with GeoServer: SLD and library mode

Blog ‐ Posted on 16.04.2012 by simone giannecchini

Hi all,today I want to delve a bit in the dynamic styling abilities that GeoServer provides.GeoServer fully supports a client's ability to specify a custom SLD 1.0 style instead of a built-in named style, this can be done in different ways:adding a reference to a internet accessible sld file via the &sld=url parameterspecifying the full SLD, url-encoded, in the request URL via the SLD_BODY=fullStyleDefinitionHere parameter POST-ing a GetMap XML document, as defined by the SLD 1.0 spec POST-ing the usual GET request, where each KVP parameter is sent over as a form parameter (this is a GeoServer extension)Let's have a...
