[mapserver-users] mapcache - transparency, surrounding area color, performance when assembling images (pink tiles)

[Mark Volz]

Hello,

First,  I am having trouble figuring out how to get transparency to work in mapcache when using a Mapserver/WMS source.  Does anyone have an example of how to store a transparent mapcache with a Mapserver wms source?

Next,  The color of my cache is fine, however the surrounding area outside of the extent of the cache is black.  Can that be changed to white, or transparent?

Third,  Mapcache seems really slow when it needs to assemble images.  I am getting plenty of pink screens, and the response time is usually greater than 5 seconds.  Mapcache is much faster when I use <full_wms>forward</full_wms>, so I know the problem is not the source wms.  Does anyone have an idea as to why the performance is poor when assembling images?

Thank You
