Detailed Description

A Halo is a type of Fill that is applied to the backgrounds of font glyphs.

A Halo fills an extended area outside the glyphs of a rendered text label to make the label easier to read over a background. The Radius element gives the absolute size of a halo radius in pixels encoded as a floating-point number. The radius is taken from the outside edge of a font glyph to extend the area of coverage of the glyph (and the inside edge of "holes" in the glyphs). The halo of a text label is considered to be a single shape. The default radius is one pixel. Negative values are not allowed. The default halo fill is solid white (Color "#FFFFFF"). The glyph’s fill is plotted on top of the halo. The default font fill is solid black (Color "#000000"). If no Halo is selected in the containing TextSymbolizer, then no halo will be rendered.
