When drawing a shape is it supposed to use the layer transparency?

[Steve Lime]

Transparency is a layer-level parameter so drawing a shape directly won't work. You have
a couple of options:

  - use a layer with transparency defined for drawing (this need not be the parcel layer) and add the shape to that layer, then draw

  - grab a unique attribue value from the result shape and use is to set a an expression in the parcel layer to hilight the shape, that is
one class for selected features and one for everything else

  - you might even be able to combine the attribute query and drawing using class expressions depending on the backend data
source

The first option is likely the fastest...

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);
