All properties that previously used underscores, ie '_' now use dashes ('-'). So, for example: 'allow_overlap' is now 'allow-overlap'
- Mapnik 0.7.2 has compatibility with both syntaxes as of r2579
- Mapnik 2.0 moved to only dashes in r2582
- properties changed include:
['paths_from_xml','minimum_version','buffer_size','face_name,fonset_name','clear_label_cache','vertical_alignment','halo_fill','halo_radius','text_ratio','wrap_width','wrap_before','wrap_character','text_transform','line_spacing','label_position_tolerance','character_spacing','min_distance','minimum_distance','avoid_edges','allow_overlap','max_char_angle_delta','horizontal_alignment','justify_alignment','unlock_image','no_text']
This change affects the PolygonSymbolizer, LineSymbolizer, RasterSymbolizer, and BuildingSymbolizer only.
All CSSParameters have been removed, so for example, this:
<PolygonSymbolizer>
<CssParameter name="fill">yellow</CssParameter>
</PolygonSymbolizer>
is now:
<PolygonSymbolizer fill="yellow" />
