PHP/MapScript - Reference

[Aaron Racicot]

Bernardo,

You need a reference map definition in your mapfile that points to the reference image.  This can be done statically in your mapfile or you need to create one in php-mapscript as a referenceMapObj embedded in the mapObj.  Here is an example of a definition in a mapfile:

  #
  # Start of reference map
  #
  REFERENCE
    IMAGE "/var/www/html/apps/siuslaw_epa/data/ref/blue_marble_us_200_150.gif"
    EXTENT -170 10 -64 90
    SIZE 200 150
    STATUS OFF
    MINBOXSIZE 1
    MAXBOXSIZE 200
    COLOR -1 -1 -1
    OUTLINECOLOR 255 255 255
    MARKERSIZE 10
    MARKER 'star'
  END

In this example I then do the following in php-mapscript:

  $img_ref = $oMap->drawReferenceMap();
  $url_ref = $img_ref->saveWebImage();

Hope this helps... and try reading up on the php-mapscript class reference:
