[MapProxy] How do I get these tile sets overlayed with transparency?

[Daniel Cebulla]

Hi Michael,

I don't remember it for 100 %, but I think the key changing setting is 
to set "paletted" to "false" in the global config.

As the docs website is not availably at the moment have look at the 
github file:
https://github.com/mapproxy/mapproxy/blob/master/doc/configuration.rst

There it says:
paletted: Enable paletted (8bit) PNG images. It defaults to true for 
backwards compatibility. You should set this to false if you need 24bit 
PNG files. You can enable 8bit PNGs for single caches with a custom 
format (colors: 256).

Only 24 Bit PNGs have an alpha channel. And as "transparent" is difined as:
transparent: true if the image should have an alpha channel.

I think you have to sett "paletted" to "false" to get this work.

I am using transparent caches and I have set this option to false, so I 
think this should solve the issue.

Let us know if it worked!
