[mapserver-users] watermark

[Milo van der Linden]

Hi list,

I am trying to create a watermark on an wms aerial photo layer using the 
following technique:

- Create a new shp for my area of interest
- hatch the shape with an image
- set the image to a very low opacity
- add this shape as layer to my mapfile
- trying to set the layer to "always on top, always on" for the aerial photo

I am failing at the last step, somehow I cannot get the layer to be 
always on. If I do a wms request calling both layers: aerial_photo and 
watermark, I get the effect I want, but when I only call the 
aerial_photo, my watermark is not showing, whether I set it to ON, 
DEFAULT, or OFF.

Is there a way to make sure this layer is always shown? Or am I trying 
to use a wrong technique?

Any help appreciated!

Kind regards,
