• Sample XML Configuration

Symbolizer that specifies rendering of a TrueType Glyph .

New in 0.8 (aka Mapnik2) but removed in Mapnik 2.1 after the TextSymbolizer gained the ability to render raw strings using Expressions and gained the ability to rotate text using the expression-based orientation property.

Renders a TrueType Glyph at the Feature's label location (usually the center of polygons/lines and on the point themselves).

(see source for sample usage)
