[Mapserver-users] Transparency on Querymap hilite

[Steve Lime]

Query maps can be mimiced using regular old layers. Using your example
you could add a second class with an expression that you set only once a
query has been done. In regular modes the expression wouldn't match and
would be skipped. This works nicely when only a few features are
selected and it's easy to write an expression to isolate them. In your
case it might look like:

   CLASS
     # selected features are drawn with this 
      EXPRESSION "%myexpr%"
      COLOR 255 0 0
      OUTLINECOLOR 143 143 143
    END

It goes before the other class and is only active when you pass
mapserver a variable called myexpr. Just a thought anyway. Otherwise the
request for transparency in a querymap should be filed in bugzilla...

Dear Listmembers,

The final client of my cartographic intranet solution whishes
transparency on the queried geographic objects to "see behind the
objects".

Is there a way to apply a TRANSPARENCY on "HILITE" of QUERYMAP in
mapfile. 
Probably not...
Is there an other way to obtain a sort of "transparency effect"
(without changing the layer properties) .
Thanks a lot 
                Bernd

  END
    STATUS ON
