Hello all. I am trying to set diferent symbols to point shapes in a
layer, but after adding 50 symbols the function
$map->getSymbolByName($filename)
returns -1 and the symbol does not apear in the map.
Here is a piece of my code:
$layer = ms_newLayerObj($Map);
$layer->set("name", 'graph');
$layer->set("type", MS_LAYER_POINT);
$layer->set("status", 1);
$shape_file = ms_newShapefileObj($Map->shapepath.'/graph',
MS_SHP_POINT);
$dbfFile = dbase_create($Map->shapepath."/graph.dbf",
array(array("IGDS_CLASS", "C", 150, 0), array("VALOR", "C", 150,
0)));
$idx_class = 0;
while ($j<52) {
$class = ms_newClassObj($layer);
$class->set("name", "class_name");
$class->setexpression("'".$idx_class."'");
$class->set("symbolname", $path.$idx_class.".png");
$pt = ms_newPointObj();
$pt->setXY($long + 50, $lat+120);
$line = ms_newLineObj();
$line->add($pt);
$shape = ms_newShapeObj(MS_SHAPE_POINT);
$shape->add($line);
$shape_file->addShape($shape);
dbase_add_record($dbfFile, array($idx_class, 0));
$idx_class++;
}
$shape_file->free();
dbase_close($dbfFile);
$layer->set('classitem', 'IGDS_CLASS');
$layer->set('data', 'graph');
Is this a bug of mapserver?
Am I doing something wrong?
Is there a better way to do this?
Can anyone please help me?
