Highlight Features

[Bart van den Eijnden]

Use 2 LAYERs. Draw the selection on top of the normal layer with a different color.

Hello All,

Using PHP/Mapscript 4.4.  Trying to highlight feature in polygon layer,
such as subdivisions.  I use:

   $layer->setFilter("");
   $sFilter = "('[subdivname]' = '$sSubDivsion')";
   $layer->setFilter($sFilter);

PROBLEM: ONLY THAT SPECIFIC FEATURE IS DRAWN.  If I use:

   $sFilter = "('[subdivname]' != '$sSubDivsion')";

PROBLEM: ALL FEATURES DRAWN EXCEPT ONE OF INTEREST, WHICH IS OK EXCEPT IN
PLACES WHERE THE BOUNDARY OF THE FEATURE OF INTEREST HAS NO SURROUNDING
POLYGONS.  WHEN THIS IS THE CASE, THE BOUNDARY OF FEATURE IS NOT SHOWN.


QUESTION: HOW DO I DRAW ALL FEATURES WITHIN POLYGON LAYER AND ALSO
HIGHLIGHT THE FEATURE(S) OF INTEREST IN A DIFFERENT COLOR

Thanks, Rob
