Oops, you're right, "drawLabelCache" is a method of the map-object, but
all the same it works for me!
Perhaps a missing LABEL-Section in the mapfile-definition of your $daLayer?

Hi Ludwig,
Layer object doesn't have DrawLabelCache method. I've tried this line and
got an error. I'm using Mapserver installed with fgs 5.4.2.
I've tried
$map-> drawLabelCache($image);
But it doesn't make any difference.

Hi,
I think there's only one line missing after $daLayer->draw($image):
$daLayer->drawLabelCache($image);

Hello,
I couldn't find documentation how to set the text labels dynamically
using
MapScript.
My application should show points with labels on the map. Points and
labels
are obtained dynamically from the database or some text file.
I add the points to the layer and draw layer as following:
$my_point = ms_newpointObj();
$my_point->setXY(-75.895, 45.9227);
$my_point->project($projInObj,$projOutObj);
$line = ms_newLineObj();
$line->add($my_point);
$shape = ms_newShapeObj(MS_SHAPE_POINT);
$shape->add($line);
$shape->set(text, 'new point');
$daLayer->addFeature($shape);
$image=$map->draw();
$daLayer->draw($image);
$image_url=$image->saveWebImage();
Points are displayed on the map, but no text. What am I doing wrong?
I will appreciate any help,
Helen
