Thank you. The bitdepth of the source-PNG is 32 bit.<br>
So there seems to be another issue.<br>
<br>
Any help appreciated, MArco<br>

properties, "Bit depth" for ex. you should have 32 bits per

Thanks for your prompt response.<br>
<br>
The WMS-service is not under my control.<br>
It's an ArcGIS10 server (the one serving the layer which
doesn't like te be opaque). <br>
Probably the image is quantised, but that's what we want
as we are aiming on mobile use.<br>
<br>
Is there a way to see if the image is quantised?<br>
Why is there a problem? Can it be mitigated?<br>

Do you have quantisation for the outputformat at the
mapserver side? if so, this can be the problem.<br>

I've the mapproxy config to my liking.
Everything is working fine except for the
opacity on a source.<br>
<br>
I would expect a layer pointing to a cache
pointing to a source with definition:<br>
wms_Bedrijventerrein:<br>
concurrent_requests: 4<br>
image: {opacity: 0.1}<br>
req: { layers: Bedrijventerrein,
transparent: true, url: '<a
moz-do-not-send="true"
href="http://myservice.nl/MapServer/WMSServer"
target="_blank">http://myservice.nl/MapServer/WMSServer</a>'}<br>
seed_only: false<br>
supported_srs: ['EPSG:28992']<br>
type: wms<br>
wms_opts: {featureinfo: true}<br>
to be rendered almost transparent when
requested and/ or merged on top of other
layers. <br>
The result is unfortunately fully opaque.<br>
<br>
Can anyone point me to what I am doing wrong.<br>
<br>
I've isolated the problem and tested it in the
configuration attached below.<br>
<br>
Any help greatly appreciated,<br>
