[Geoserver-devel] by layer interpolation

Mauro:

I was looking into layer group interpolation quality for a customer, and had a chance to step through the code associated with the recent back port of GEOS-7005 and GEOS-6614.

The following code in RenderedImageMapOutputFormat:

if(request.getInterpolations() != null && !request.getInterpolations().isEmpty()) {
int count = 0;
List interpolations = request.getInterpolations();
for(Layer layer : mapContent.layers()) {
if(count < interpolations.size()) {
Interpolation interpolation = interpolations.get(count);
if(interpolation != null) {
layer.getUserData().put(StreamingRenderer.BYLAYER_INTERPOLATION, interpolation);
}
}
count++;
}
}

This code grinds through the request interpolations assigning them to mapContent layers.

When a layer group is used these two lists no longer line up (as the number of mapContent.layers is greater than the number of interpolations provided).

Hum... layer groups are expanded into the list of layers at the kvp parser,
do not remember if we require these params to be already
expanded in the request, or if the kvp parser attempts an expansion of its
own.

As said many times, "layer groups do not exist" inside GeoServer, they are
aliases wiped out before we start processing requests
(inside the request parsers).

I will have a look at the layergroup behaviour for the interpolations parameter (not sure, I didn’t test this scenario explicitly). I guess we have “special” behaviour for the styles parameter to make layers and styles list align, so I will see if we are consistent with that behaviour on the new parameter too, and yes, the layer groups list should be expanded to a list of layers by the parser.

Hi,
I prepared a pull request that should fix layer groups behaviour: https://github.com/geoserver/geoserver/pull/1057
