Re: [udig-devel] layer styles

[Jody Garnett <jody.garnett@xxxxxxxxx>]

GeoServer uses postgis; and the same "GeoTools" rendering engine that we have in uDig.

So the docs work fine; you can actually drag and drop an "sld" file on to your postgis layer to set the style XML settings etc... the two applications work together because both follow the same industry standard (ie SLD) for defining styles.

if you are really keen you can download and read the sld standard; it is free.

Thanks. Looking at the ling you gave me, you can do more on styles that I expected. My question now is, do I need to use geoserver to attach a SLD to my layer or can I just continue using postgis and attach the style programatically? What are the things you can do with geoserver that you cannot do with a direct postgis data source?

Try the style dialog (it allows you to assign an image to a point). And then look at the advanced xml page to review the resulting style data structure. You can create the same data structure using java code to get the same effect.

- http://udig.refractions.net/confluence/display/EN/Feature+Style+Pages

There is some information on building the data structure, (or even parsing that xml) in the GeoTools user guide and GeoServer docs:

- http://docs.geoserver.org/stable/en/user/styling/sld-cookbook/points.html#point-as-graphic

- http://docs.codehaus.org/display/GEOTDOC/07+Symbolizers

- http://docs.geotools.org/latest/tutorials/map/style.html

Moovida it would be great to improve the docs for your new style pages; or add a "task" illustrating how to answer Marco's question.

Cheers,

Hello,

I'm new to uDig. I'm building a little application on top of uDig. I would like to know if it is possible to show a little image instead of a point, and in general how do I assign a style to a postgis layer programatically.
I hope you can point me in the right direction.

Thanks,

Marco
