Detailed Description

An AnchorPoint identifies the location inside of a text label to use an 'anchor' for positioning it relative to a point geometry.

The AnchorPoint element of a PointSymbolizer gives the location inside of a Graphic (or label) to use for anchoring the graphic to the main-geometry point. The coordinates are given as two floating-point numbers in the AnchorPointX and AnchorPointY elements each with values between 0.0 and 1.0 inclusive. The bounding box of the graphic/label to be rendered is considered to be in a coordinate space from 0.0 (lower-left corner) to 1.0 (upper-right corner), and the anchor position is specified as a point in this space. The default point is X = 0.5, Y = 0.5, which is at the middle height and middle length of the graphic/label text. A system may choose different anchor points to de-conflict graphics/labels.
