Hello-<br>
<br>
I have an update for this problem with using external graphics for SLD requests.<br>
<br>
I attempted to use the SLD file at
<a href="http://www2.dmsolutions.ca/msapps/world_testdata/tests/sld_tests/sld_polygon_fill_symbol_external.xml">http://www2.dmsolutions.ca/msapps/world_testdata/tests/sld_tests/sld_polygon_fill_symbol_external.xml</a><br>
<br>
with the ms4w-Chameleon OGC sample application (which contains the
proper layer - WorldGen- for the SLD) and received the same error
messages that I've been receiving with my own application:<br>
<br>
<b>Warning</b>: [MapServer Error]: loadSymbol(): Symbol of type PIXMAP has no image data.
in <b>C:\ms4w\apps\chameleon\htdocs\common\wrapper\map_session.php</b> on line <b>215</b><br>
<br>
<b>Warning</b>: Failed to open map file /ms4w/tmp/sess_43264a06bd7bc/1126582974-2202.map in <b>C:\ms4w\apps\chameleon\htdocs\common\wrapper\map_session.php</b> on line <b>215</b><br>
<br>
<b>Fatal error</b>: Call to a member function on a non-object in <b>C:\ms4w\apps\chameleon\htdocs\widgets\KeyMapDHTML\KeyMapDHTML.widget.php</b> on line <b>150</b><br>
<br>
<br>
Could this be a bug?? Could there be a problem with the way ms4w
is set up on our server (although we did nothing different this
time...)? Is there a copy of this same sample application available
through the MapServer website so that I could test the same application
on a different server (if so, I haven't been able to find it)?
This is a problem I just haven't made any headway on and any
suggestions would be greatly appreciated!<br>

Hi-<br>
<br>
I have created a temporary directory with all of the associated files:
the context file, the sld file, the temp map file, the temp image file,
and the wms map file.<br>
<a href="https://mywebspace.wisc.edu/jrzeisloft/web/temp/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">https://mywebspace.wisc.edu/jrzeisloft/web/temp/</a> <br>
<br>
I don't know that you'll need all of those, but I'm not really sure
where the problem is. Other (non-external) SLDs can be applied
without a problem. <br>
<br>
The application I am working on is located at
<a href="http://maps.aqua.wisc.edu/lscmp/viewmaps.phtml" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://maps.aqua.wisc.edu/lscmp/viewmaps.phtml</a>. The context I was
using to test the external graphic SLD is the Bluff Stability
context. The layer I was using is the Bluff Profiles layer.
The SLD I was trying to open is at
<a href="https://mywebspace.wisc.edu/jrzeisloft/web/temp/sld_symbol_external.xml" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">https://mywebspace.wisc.edu/jrzeisloft/web/temp/sld_symbol_external.xml
</a>.<br>
<br>
I can't think of any other information to offer: I simply go to the
application, open the bluff stability context, select the bluff profile
layer (though I am not sure this is necessary), click the Open SLD tool
button, and browse to the SLD file. Then the error occurs. <br>
<br>
Thanks for your help!<br><span class="sg">

Not sure what the initial error is but you could check the map file<br>1126209374-4254.map and see if the inline symbols created reference an<br>existing png or gif file.<br><br>I would also be nice if you could provide a quick was (+ all realted
<br>files) to reproduce this bug. At this point I am not sure how to<br>reproduce it.<br><br>Later,<br><br>Jennifer Zeisloft wrote:<br>> Hello All-<br>><br>> I am starting to play with SLD and am attempting to use an external
