Dynamic map title

Thu Aug 26 12:16:02 PDT 2004

I think I am getting closer (thanks to your help) but still don't get it.
Let me resume - I have this annotation layer with a point feature and a
text, which is the (sub)title of my map.
With it's default values it is perfectly visible, including font and color
specifications. Trouble starts when I try to change the text via code...

LAYER
     NAME       "subtitESP"
     STATUS     ON
     TRANSFORM  FALSE
     TYPE       ANNOTATION
     FEATURE
        POINTS  435 10  END
        TEXT    "Merops apiaster"      # this is the text to be changed!!!!
     END
     CLASS
          LABEL
               TYPE      TRUETYPE #BITMAP
               FONT      verdana-italic
               SIZE      12
               POSITION  LL
               COLOR     160 90 0
          END
 #    TEXT      "Steve's method"
     END
 END

..Steve suggested to use the class text property instead of the feature so I
commented out the feature part, but no luck.....

<?php
$map_path="c:/web/";
$map_file="test.map";
$map=ms_newMapObj($map_path.$map_file);
$img=$map->draw();
$imgURL=$img->saveWebImage();

$subtitESP=$map->getLayerByName('subtitESP');

# Steve's suggestion: edit the TEXT property of the class:
$clObj=$subtitESP->getClass(0);
//$clObj->setText('Steve');
.....here I get 'Wrong parameter count for settext()'

# ..Sean and Eric suggested more or less the same: to remove the feature and
add a new feature: This is the part where I get a bit lost - do I have to
specify the line object? set the point coordinates to map or to image
coordinates? I get no error message but the new text doesn't show either.
$myshpObj=ms_NewShapeObj(MS_SHAPE_LINE);
$p=ms_newPointObj();
$l=ms_newLineObj(); #  according to the MapScript Class Ref - this is the
onlytype that can be added to a shape???
//$p->setXY(1185001, 4879000);  # (635,10) map or img coords????
$p->setXY(635, 10);
$l->add($p);

$myshpObj->add($l);
$myshpObj->set('text', 'Sean and Eric');
//$subtitESP->addFeature($myshpObj, MS_SHAPE_LINE);
$subtitESP->addFeature($myshpObj);

$subtitESP->draw($img);
$imgURL=$img->saveWebImage();
