Enable "hatching" with a well-known-mark called 'hatch'
-------------------------------------------------------
Key: GEOT-829
URL: http://jira.codehaus.org/browse/GEOT-829
Project: GeoTools
Type: Improvement
Components: wms, styling, renderer, render
Versions: 2.1.1
Environment: All
Reporter: Saul Farber
Assigned to: Jesse Eichar
Priority: Trivial
Attachments: crosshatch-wkmark-r18876.patch
Our organization needs to have "hatching" as a symbolization possiblitiy. It
takes the form of many little vertical lines filling a polygon, or (with
rotation) many little horizontal lines.
You can also overlay lines rotated at 90 degrees to each other to create a
"grid" or "lattice" of little squares/diamonds.
Since it's implemented as a well-known-mark, it's just another java2D
GeneralPath, and can be styled just like anything else.
The OGC-standard way to do this would be to create different "hatch" tiles for
every single color and thickness of hatch one could ever possibly conceive of,
and that seems inefficient.
Since my motivation is Geoserver, the patch is against the 2.1.x renderer, but
as soon as geoserver moves to 2.2.x I'll forward-port this patch to the 2.2.x
renderer.
