<div class="moz-cite-prefix">Thanks, it worked!<br>
<br>
Now I'm trying to solve the same problem on png output, <br>
if a request is outside the extent it will return a trasparent
png, and that is ok, <br>
when I request a tile that is half-in and half-out the extent, the
half-out part <br>
should be transparent instead of white.<br>
<br>
Any suggestion on how to solve this?<br>

<div>Hi, <br>
I tried with your suggestion to use a mixed image format
but with unsuccessful results.<br>
For my case I just need to force that black background
color to white, is there anyplace in<br>
mapcache code where I can change it?<br>
<br>
Any suggestion on which part of the code I have to look
would be enough.<br>
<br>
Thanks,<br>
Daniele

<div>The background color isn't configurable,
although that could become a configurable option
with a bit of funding. Your other option might be
to use a "mixed" image format, which will use JPEG
compression for complete tiles, and png with a
transparent background for tiles that are
half-in/half-out.</div>

is a possibility to change the background

when i request a tile with an extent that
