Hi, everybody<br>
<br>
we are using the GDAL WMS driver for getting maps from a public WMTS
service, <a class="moz-txt-link-freetext" href="http://www.basemap.at">http://www.basemap.at</a>. Anyway, the resulting image does not
look smooth. In particular, I would guess that the the image was
scaled with something like a nearest neighbor algorithm.<br>
So my question is simply, if I can switch the interpolation method
in some place.<br>
<br>
The XML file, taken from
<a class="moz-txt-link-freetext" href="http://gisforge.wordpress.com/2012/11/06/basemap-at-wmts-layer-in-qgis/">http://gisforge.wordpress.com/2012/11/06/basemap-at-wmts-layer-in-qgis/</a>,

-outsize 250 250 basemap_at.xml basemap_at.jpg<br>
<br>
As can be clearly seen, the labels are hard to read.<br>
