The spec says (SLD 1.0, page 62),"RULE. Optional. Rule of style to produce legend graphic for, if
applicable=
=2E=20
In the case that a style has multiple rules but no specific rule is

ah, I think "at this time" you mean when getting the legend graphic url
stated
in the capabilities? that's right. It is clear at this time the returned
image MUST be of the size stated on the capabilities. That was a geosever
error.
By the other hand, you do can issue rule specific requests, as the spec
says,
and geoserver supports it.
It could make more sense to a high tech client like udig, and could be
pretty
difficult for a html based one. So you have the flexibility to treat them
as
a black box (an get what the server wants to return in order to provide a
"representative" graphic of all the rules that apply), or take the control
and get a graphic for each rule.cheers,
Gabriel.

You are correct - it was me going around in circles.
Problem is I want a graphic for my layer - and the spec clearly says
that this is a legend graphic (not a layer graphic).
Thanks for find the spec, I was looking in the WMS specs.>The spec says (SLD 1.0, page 62),

I think the best compromise I can do is request the size I want (16x16)
and figure out a way to smoothly handle a different size. I am going to
try and take just the first 16x16 (in case the answer was 16x32 or
something).Cheers,

Subject: [Geoserver-devel] GISONEI was looking through source forge today and did a search for geotools:
GeoTools, the java GIS toolkit
GeoTools is *the* open source java GIS toolkit. Used for OGC based
projects via GeoAPI interfaces. Includes two great SLD based renderers,
raster access and reprojection. Plugns fo Shapefile, ArcGrid, ArcSDE,
Postgis, OracleSpatial, MySQL and many more.Experimental GIS tools in Java
Experimental utilities in Java for geographic information and remote
sensing in environmental science. Seagis is built on top of Geotools 2,
which is an OpenGIS implementation. Seagis classes moves to Geotools 2
when (and if) they become mature enough.GISONE
GISONE is an Open J2EE Spatial Framework (OJSF) for building spatially
enabled Web applications. The software builds upon popular OpenSource
Standards like OpenGIS and libraries like GeoTools, Struts , JBOSS and
others.Things to note:
a) GeoServer did not appear
b) what is GISONE?I am CCing the contact person with this email, perhaps they would like
to play with GeoServr?Jody
