[Mapserver-users] Combining images from several mapfiles

[Jan Hartmann]

Oh, and by the way, you can even set tranparency of the different images 
within the browser in the style items:

Mozilla: <img style="-moz-Opacity:0.5">
IE       <img style="filter:alpha(opacity=50)">

I think both browsers will accept a combined style item:

<img style="-moz-opacity:0.5;filter:alpha(opacity=50)">

Of course, this way you are doing *two* Mapserver requests for one map, 
which requires much more server processing than one map with two layers.

One solution would be to use stacked images in the browser:

<img id=i1 style="position:absolute;left:0;top:0">
<img id=i2 style="position:absolute;left:0;top:0">

<script>
img1 = document.getElementById("i1")
img2 = document.getElementById("i2")
img1.src = "http://.../mapserv?map=first.map&mode=map"
img2.src = "http://.../mapserv?map=second.map&mode=map"
</script>

Of course img2 has to be transparent for img1 to show through.
