Hi there,
I did a quick test using php mapscript and an svg output. The poplace
layer in the map file is a point layer and has a class with a label
object (note that there is no labelitem set)
LAYER
NAME popplace
TYPE POINT
STATUS ON
...
CLASS
style
SYMBOL 'circle'
SIZE 6
COLOR 0 0 255
END
LABEL
COLOR 255 0 0
# FONT fritqat-italic
FONT Arial
TYPE truetype
SIZE 12
ANGLE 10
POSITION AUTO
PARTIALS FALSE
OUTLINECOLOR 255 255 255
END
...
script looks something like this
$oMap = ms_newmapobj("c:/msapps/gmap-ms40/htdocs/gmap75.map");
$oShp = ms_newShapeObj(MS_SHAPE_POINT);
$oLine = ms_newLineObj();
$oLine->addXY(-2299954.0642738,-612631);
$oShp->add( $oLine );
$oShp->set("text", "mytext");
$numlayers = $oMap->numlayers;
for ($i=0; $i<$numlayers; $i++)
{
$oLayer = $oMap->getlayer($i);
$oLayer->set("status", MS_OFF);
}
$oLayer = $oMap->getlayerbyname('popplace');
$oLayer->set("status", MS_ON);
$oLayer->addfeature($oShp);
$img = $oMap->draw();
$url = $img->saveWebImage();
header("Content-type: image/svg+xml");
$url = $img->saveImage("");
It produces an svg point with the label my text :
...
<!-- START LAYER popplace -->
<ellipse cx="39" cy="586" rx="3" ry="3" fill="#0000ff" />
<text x="38" y="581" font-family="Arial" font-size="12pt" fill="#ff0000"
stroke="#ffffff" stroke-width="0.5" transform="rotate(-10.000000 38
581)">mytext</text>
</svg>
Not sure what the issue would be in your case, the only time I did not
have the text produced was when I set the labelitem object. Could that
be the case ?

Hi,
I am using addFeature to dynamically add site locations with a label to a map.
It's Perl mapscript.
@sites is an array of hash references, $sitesLyr is from the map file:
###############
foreach my $site (@sites) {
my $site_pt = $$site{'site_loc'};
$site_pt =~s/.*\((.*)\)*./$1/; # extract the points x and y
my $line = new mapscript::lineObj();
my $siteShp = new mapscript::shapeObj($mapscript::MS_SHAPE_POINT);
my $point = new mapscript::pointObj();
my($x,$y) = split(/ /, $site_pt);
$point->setXY($x,$y);
$line->add($point);
$siteShp->add($line);
$siteShp->{text} = $$site{'site_name'};
$siteShp->setBounds();
$sitesLyr->addFeature($siteShp);
}
my $img = $map->draw();
#############
This works perfectly for the usual PNG output map. Using the same routine for a
SVG 'image' results in the symbols/markers getting plotted, but the labels are
missing. If I switch to a static shapefile for this layer, the labels do appear
in the SVG.
Is there anything special with SVG output and the 'addFeature' method for layers
that I am missing?
Thanks,
Martin
