[udig-devel] [jira] Created: (UDIG-672) BasicWMSRenderer2 + WMS connection from MapServer 
BasicWMSRenderer2 + WMS connection from MapServer 
--------------------------------------------------

         Key: UDIG-672
         URL: http://jira.codehaus.org/browse/UDIG-672
     Project: uDIG
        Type: Bug

  Components: wms  
    Versions:  UDIG 1.1.M2    
 Environment: WMS connection from MapServer (http://mapserver.gis.umn.edu )
    Reporter: Vitali Diatchkov
 Assigned to: Richard Gould 


This bug appears when MapServer from University of Minnesota as a WMS server  is used.

in BasicWMSRenderer2.render(...) routine  "transparent" property of GetMapRequest instance is always set to "true":

request.setTransparent(true);

but if MapServer is used through WMS protocol and "format" parameter has the following values: "image/jpeg"  or "image/bmp", whatever format that is not able to be transparent - in this case MapServer doesn't generate image.

Only if "image/png" is specified as a format parameter value - only in that case MapServer handles TRANSARENT=TRUE in WMS GetMap query. If "image/jpeg" or "image/jbmp"  formats are specified and TRANSARENT=TRUE then an error happens.

But combinations of parameters "TRANSARENT=FALSE&FORMAT=image/jpeg" or "TRANSARENT=FALSE&FORMAT=image/bmp" works fine.

So, in BasicWMSRenderer2.render(...) the "transparent" property of GetMapRequest instance should be set depending on image format to be used.

I can provide URL to WMS connection from MapServer to take a look into the problem if it is needed, just request in comments.
