Hi Andrea
Thanks you.
Has anybody experience with that on geoserver ? Quality seems to be bad,
how is it with performance?
I tried it with mapproxy. There it’s possible to choose the interpolation
type – so we have to decide if we want to do that project with geoserver as
some other before or to switch to mapproxy for this.
Has anybody experience with mapproxy or with
Our aim is to integrate some other wms in our GIS-Project. For not to have
problems when one of these WMS don’t work, we want to cache them. As our
GIS-System can choose various zoom-levels we are depending on the
interpolation.
Thanks for any advice.
Regards,
Christian

Christian,
Jukka pointed you in the correct direction. However, I would strongly advise
a) to stick to one of the scale sets in the OGC WMTS standard, b) to ask
your users to get them using the getCapabilities statement and only look at
them using the correct scale/resolution and c) ask them not to reproject the
images because they just look bad.
Agreed, if the layer in question is a raster one, the results should be
decent,
but if you have vector data, especially with labels on the map, the
result will be far from pleasant
That said, I'm wondering what interpolation GWC uses... by looking at the
code it seems it's using nearest neighbor (don't see any hints passed to
Graphics2D specifying the interpolation), which is guaranteed to return
rather ugly results, allowing the admin to choose bilinear or bicubic would
allow for better quality in output.
You might want to open a feature request against GWC to have a
configurable interpolation.
Cheers
Andrea
