Ed,
Thanks for the reply. I have and had tried moving the layer definition to=
=20
the beginning and the end of the map file with the same results. I had=20
figured it to be more php/mapscript related issue, though when I draw the=20
layer last in php/mapscript I also have the same result - the annotation=20
layer is drawn under the other layers. Any other ideas?
Thanks,
Dan

Thanks for the reply. I have and had tried moving the layer
definition to the beginning and the end of the map file with the same

result - the annotation layer is drawn under the other layers. Any

<dd>Hello,<br><br>
<dd>I have searched through the archives w/o much luck on determining
what I am doing wrong. <br><br>
<dd>I am using MapServer v3.5 and am trying to draw an annotation layer
so it is always the last layer to be drawn and shows on top of all other
layers. Right now it is always drawn under my other layers and is
not seen. I also use PHP/Mapscript to create the maps and have
tried to force this layer to be drawn last, w/o success. Can anyone
clue me in on the method to ensure this layer is always draw last, either
via the map file only or via php/mapscript? Below is the map file
entry for the layer and the php/mapscript snippet.<br><br>
