hi all

im trying to fill a polygon with dashed lines with this standard 4.0 4.0 2.0 4.0. But i dont know if it is possible, all i can do is to use this standard for the outline with <sld:CssParameter name=“stroke-dasharray”> 4.0 4.0 2.0 4.0</sld:CssParameter>.
here is an extract of my .sld
sld:Fill
<sld:CssParameter name=“fill”>#ECE9D8</sld:CssParameter>
<sld:CssParameter name=“fill-opacity”>1.0</sld:CssParameter>
<sld:CssParameter name=“fill-dasharray”>4.0 4.0 2.0 4.0</sld:CssParameter>
</sld:Fill>

instead of “stroke” i use “fill”, but is doesn’t work. someone know how to solve it?

thanks

You can't use a dash array for fills. See
Styled Layer Descriptor - Open Geospatial Consortium for more details. You
could use a graphics fill to achieve the same effect I think.

That's not in the SLD spec, so you can't do it that way.
You have to prepare an image (png, gif) that has the pattern, in a way
that putting togheter copies of these images in a tiling the result
is seamless (that is, you don't see any discontinuity at tile borders).
