<p class="MsoNormal"><span lang="DE-CH">I would like to publish a raster-image with umn mapserver -> mapproxy. Everything is o.k. but the color depth of the mapproxy output is bad, compared to the output of mapserver . The image delivered by mapserver is much
smoother than the image from mapproxy, where similar colors are aggregate to one color.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="FR-CH">I tried the options « mode: RGBA », « colors : 0 » and switched from png to jpeg – but nothing improved the color debth of the image. Do you have any suggestions?<o:p></o:p></span></p>
