I have a point feature (which I draw as a symbol) I am trying to label
and isn't working (C++). I modified my data so this symbol is the only
thing being drawn.
I have two different styles setup. The rule to draw the symbol is:
<Rule>
<Filter>[mapnik:geometry] = '1' and [point_symbol] =
'cemetery'</Filter>
<PointSymbolizer file="syms/cemetery.png" type="png" width="20"
height="20" allow_overlap="true"/>
</Rule>
which is being drawn. I have a separate rule for the text (I had this
inside the above rule but it didn't make a difference)
<Rule>
<Filter>[mapnik:geometry] = '1' and [point_symbol] =
'cemetery'</Filter>
<TextSymbolizer name="name" face_name="DejaVu Sans Bold" size="8"
fill="green" dy="-25" halo_radius="1" wrap_width="0"/>
</Rule>
Looking in the mapnik source, adding in my own debug, I see in
src/agg_renderer.cpp::process(text_symbolizer ...) that the code is
getting down into the POINT_PLACEMENT block and is calling
finder.find_point_placement(). But the loop just below (for (unsigned
int ii = 0; ii < text_placement.placements.size(); ++ii)) is never
executing.
I seriously doubt there is a problem in the mapnik library, so I assume
I am doing something wrong. Any ideas? Or do I need to dive into the
find_point_placement() method?
