This is the list of properties when using Mapnik 2.3 (use -t mapnik-2.3 when loading mapcss file).

  • The value of properties marked with an asterisk (*) in the "Compatibility MapCSS 0.2" column need to be predictable at compile-time; if not, a warning will be issued when compiling. Features might be missing in the rendered image.

Rendering order

In contrast to the MapCSS 0.2 specification the following rendering order is used:

  1. Objects with lower layer (see below) should always be rendered first.
  2. Within a layer, first all fills are rendered, then all casings, then all strokes.
  3. Within each of those categories, objects are ordered according to z-index.
  4. If all of the above are equal, the order is undefined.

Finally:

  • By default, all icons are rendered as if they are on layer 100 (defined by property 'point-layer')
  • By default, all labels with text-position!=line are rendered as if they are on layer 101 (defined by property 'point-text-layer')
  • By default, all labels with text-position=line are rendered as if they are on layer 102 (defined by property 'line-text-layer')
  • By default, all shields are rendered as if they are on layer 103 (defined by property 'shield-layer')

General properties

CSS parameter Description Default value Compatibility MapCSS 0.2
layer the highest level of ordering objects the value of tag 'layer' (or 0) see below

z-index specify the order of objects in each layer: The objects with higher z-index are drawn on top of objects with lower z-index 0 YES
  • Property 'layer': MapCSS 0.2 does define the rendering order dependend on the layer-tag of the objects, but does not define a way to change that order from the stylesheet.

Fonts

There's a fontset for each font-family / font-weight / font-style combination, defined in default-template.mapnik. There's a default fallback to unifont too (which might change in the future). The name of the fontsets is "font-family - font-weight - font-style", e.g. "DejaVu Serif Condensed - bold - italic".

Also all possible font-families are defined in default.mapcss in the @values font-family clause.
