Hi all,

Below is a piece of code that I am working on to change the size of =
labels.  The label size does not change using either condition:

1. $new_label_size =3D $label_size * 2;

or

2.    $new_label_size =3D 40;

Is there some function I am missing like a set(...) function ??

if (some condition)

{

    print " <i> The layer is : $layer->name </i> <br>";

    $class =3D $layer->getClass(0);

    $label_size =3D $class->label->size;

    print " <i> The old label size is : $label_size </i> <br>";

    //$new_label_size =3D $label_size * 2;

    $new_label_size =3D 40;

    $class->label->size =3D $new_label_size;

    print " <i> The new label size is : $new_label_size </i> <br>";

}

The layer :

LAYER
  NAME "my_text"

  STATUS OFF
  DATA "d:/layer/TEXT_text"
  TYPE ANNOTATION
  LABELITEM "TEXTSTRING"
  CLASS
    COLOR 255 255 0
    LABEL
      MINFEATURESIZE 40
      MINDISTANCE 150
      POSITION CC
      COLOR 255 255 0

      FONT arial
      TYPE truetype
      SIZE 10
      FORCE TRUE
    END
  END

  METADATA
    WMS_TITLE "Miscellaneous Text"
    WMS_ABSTRACT "N/A"
    WMS_SRS "EPSG:26910"
  END

END

thanks
Stephen
