[UMN_MAPSERVER-USERS] When drawing a shape is it supposed to use the layer transparency?

[Merrett, Mike]

Hi:

        I have a queryByAttributes  result which gives me a shapeobj

                -- if I then try to draw that shape it does draw but it is not transparent like the layer is set to

 

        Should it?  (is this a feature or a bug)

 

 

 

Below is the code I am using ( assume a zoom in to show the features at a scale which show that it isn't transparent - I cut out that part for clarity)

 

  $oParcelLayer = $gpoMap->getLayerByName("City Streets" );

 $y = @$oParcelLayer->queryByAttributes('street_name', $the_street, MS_SINGLE );   // assume it found one (real code has an if)

    $oResult = $oParcelLayer->getResult(0 );
    $oParcelLayer->open();
    $oShape = $oParcelLayer->getShape($oResult->tileindex, $oResult->shapeindex );

 

    $img = $gpoMap->draw();

 

    $rrr = $oShape->draw(  $gpoMap, $oParcelLayer, $img);

 

 

From the map file (relevant parts)
