Hi Jonathan,
It seems my last email to you bounced (though it clearly got to the list).
Anyway, you might want to try removing the lines:
</FeatureTypeStyle>
<FeatureTypeStyle>
Thanks for your answer,
We have just tried your suggestion, but it does not solve the problem.
By using those, you're asking GeoServer to draw the lines on separate rendering
passes. In reality you want them done on the same pass.
I want them to be drawn with consistent parameters, not really in the same pass.
Indeed, we generally want them to be drawn in two separate passes so that
crossroads look nice.
My guess is that the problem comes from the following code :
class StreamingRenderer
private void processSymbolizers(...) {
...
for (Symbolizer symbolizer : symbolizers) {
...
double size = RendererUtilities.getStyle2DSize(style) +
10;
env.expandBy(size);
...
}
...
}
}
It's the code that expands the envelope based on how big the symbolizers to be
painted are.
You should be able to dodge it by adding &buffer=20 to your requests, forcing
the
envelope buffering to a fixed value.
See if that works
Can't make it work with &buffer=20 :o(
(I can see some effects of &buffer on ponctual symbols, but not on linear
symbols)
I did not go through all the code but I wonder if the &buffer parameter is
really used for "line clipping" (I have seen it used for "feature selection"
only).
Regards,
Michaël
Cheers
