color:#1F497D'>Thanks for your tip Gracia. However using WMS to retrieve a
single and untiled image to insert on a pdf doesn’t seem like a good idea
to me. I would have to handle each tile separately, and that should be horribly
tedious. Even more, the area bounds would be delimited by these frontier tiles
and not the exact area the user desires. It is a server side process not a
service.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'> On the other hand, I don’t think the issue has to do
anything with the OUTPUTFORMAT transparency. My images are transparent pngs.
However to produce this transparent images, mapserver merges the symbols layer
together with all the other layers but without considering the symbols
transparency (in mode=map of course).<o:p></o:p></span></p>

<p class=MsoNormal style='margin-bottom:12.0pt'>Hello Manuel,<br>
<br>
I am not an expert with MapServer, but I can suggest you to do all the queries
in WMS mode (or other OGC query), because it is a standard and it already works
to you.<br>
<br>
Taking a look to my MapServer configuration, I have the following:<br>
<br>
OUTPUTFORMAT<br>
NAME gif<br>
...<br>
<b>TRANSPARENT ON</b><br>
END<br>
<br>
I hope this can help you.<br>

select a map area and get a pdf print as an output. On one my vector layers,
I’ve inserted some new png symbols with an alpha channel. Everything
works great in the WMS mode, transparency for those symbols is supported.
However, when the users wants to get the pdf of an area, I make a
mapserver CGI call in MODE=MAP to retrieve the map area as a single image an
construct the pdf output on the fly. In this MODE=MAP case, transparency for
those symbols is not supported.</span><o:p></o:p></p>
