Subject: Re: [Geotools-gt2-users] Struggling with raster styling
Hi Gabriella,
some time ago I built a fluent StyleBuilder that is meant to replace the old
clunky
one still available in the main module.
You can get it by depending on the gt-brewer module, and there are examples on
how to build programmatically styles without getting crazy in its tests, see
the Cookbook* classes:
https://github.com/geotools/geotools/tree/master/modules/extension/brewer/src/test/java/org/geotools/styling/builder
In particular for rasters:
https://github.com/geotools/geotools/blob/master/modules/extension/brewer/src/test/java/org/geotools/styling/builder/CookbookRasterTest.java
Cheers
Andrea

HI there,
I would like to be able to style rasters (read into GridCoverage2D’s) using
colormaps like the examples for geoserver here
http://docs.geoserver.org/latest/en/user/styling/sld-cookbook/rasters.html
and discussed here:
https://github.com/geotools/geotools/wiki/raster-symbolizer-support
Is there a programmatically way of doing this (ie. instead of handcrafting an
SLD)? Are there examples out there?
Or do I have to produce the SLD myself “on the fly” and then apply it? In
which case, how would I go about applying it?
And how would I come up with a colormap for a given [MIN, MAX] range of values?
I am using GT 14 at the moment…
Thanx in advance,
Gaby
