[Mapserver-users] cant label streets in mapscript -- please help

Tue Nov 11 17:57:40 EST 2003

Thank you:)
I did the test with the following php code and mapfile to get the same
labelless result :(

<HEAD>
<TITLE>TEST</TITLE>
</HEAD>
<CENTER>
<?php
    dl("php_mapscript.so");
    $map =  ms_newMapObj("demo_try2.map");
    $img = $map->draw();
    $map->drawLabelCache($img); //tried with commentted too.
    $url = $img->saveWebImage(GIF,1,1,0);

#    echo <img src="$url">;
#echo <img src=/"$url">;
?>
<INPUT TYPE="image" SRC="<?php echo $url; ?>">

mapfile:

     SIZE 8
 END
END
END

END

Have a nice day
