[Mapnik-users] XML map definitions fine in python but not qt viewer

[Gleisner Carl]

Hi,

I can render XML map definitions in python but not with the QT based  
viewer.

Using information from the XML tutorial at  XmlGettingStarted I get  
the following output.


Python
---------
>>> mapnik.render_to_file(m, map_output)
scale=0.351562
start map processing bbox=Envelope(-180,-135,180,135)
scale denominator = 1.39771e+08
start layer processing : world
datasource = 0x331010
 total shapes read=3784
end layer processing
end map processing
0.99 s


Viewer
---------
carl-gleisners-macbook:MacOS carlj$ ./viewer
loading /Users/carlj/milos/geodata/world_styles.xml
Warning: program compiled against libxml 207 using older 206
scale=75046.8
start map processing  
bbox 
= 
Envelope 
(-22326437.1984382,-20037508.3428,22326437.1984382,20037508.3428)
start layer processing : world
datasource = 0
end layer processing
end map processing
Envelope 
(-22326437.1984382,-20037508.3428,22326437.1984382,20037508.3428)
(getting the steelblue background)


XML map definition
--------------------------
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE Map>
<Map bgcolor="steelblue" srs="+proj=latlong +datum=WGS84">

  <Style name="My Style">
    <Rule>
      <PolygonSymbolizer>
        <CssParameter name="fill">#f2eff9</CssParameter>
      </PolygonSymbolizer>
      <LineSymbolizer>
        <CssParameter name="stroke">rgb(50%,50%,50%)</CssParameter>
        <CssParameter name="stroke-width">0.1</CssParameter>
      </LineSymbolizer>
    </Rule>
  </Style>

  <Layer name="world">
    <StyleName>My Style</StyleName>
    <Datasource>
      <Parameter name="type">shape</Parameter>
      <Parameter name="file">/Users/carlj/milos/geodata/world_borders/ 
world_borders</Parameter>
    </Datasource>
  </Layer>

</Map>

My environment
----------------------
Mapnik 0.6.0
Mac OS X 10.5.6
Boost 1.35 (built using macprots according to instructions)

Is this a known issue? Cannot find anything in the archive.
Where am I wrong with this thing?

Best regards, Carl Gleisner
