Used to specify the location (within the symbol) that is to be used as an anchorpoint when rotating the symbol and placing the symbol on a map. Default is 0.5 0.5 (corresponding to the center of the symbol).
x: A double in the range [0,1] that specifies the location within the symbol along the x axis. 0 specifies the left edge of the symbol, 1 specifies the right edge of the symbol. 0.5 specifies the center of the symbol (in the x direction).
y: A double in the range [0,1] that specifies the location within the symbol along the y axis. 0 specifies the top edge of the symbol, 1 specifies the lower edge of the symbol. 0.5 specifies the center of the symbol (in the y direction).
ANCHORPOINT can be used with SYMBOLs of TYPE ellipse, pixmap, svg, truetype and vector. To ensure proper behaviour for vector symbols, the left and top edges of the bounding box of the symbol should be at 0.
New in version 6.2.
If true, the symbol will be filled with a user defined color (using STYLE COLOR). Default is false.
POINTS [x y] [x y] ... END
Signifies the start of a sequence of points that make up a symbol of TYPE vector or that define the x and y radius of a symbol of TYPE ellipse. The end of this section is signified with the keyword END. The x and y values can be given using decimal numbers. The maximum x and y values define the bounding box of the symbol. The size (actually height) of a symbol is defined in the STYLE. You can create non-contiguous paths by inserting “-99 -99” at the appropriate places.
x values increase to the right, y values increase downwards.
For symbols of TYPE ellipse, a single point is specified that defines the x and y radius of the ellipse. Circles are created when x and y are equal.
If a STYLE using this symbol doesn’t contain an explicit size, then the default symbol size will be based on the range of “y” values in the point coordinates. e.g. if the y coordinates of the points in the symbol range from 0 to 5, then the default size for this symbol will be assumed to be 5.
Sets a transparent color for the input image for pixmap symbols, or determines whether all shade symbols should have a transparent background. For shade symbols it may be desirable to have background features “show through” a transparent hatching pattern, creating a more complex map. By default a symbol’s background is the same as the parent image (i.e. color 0). This is user configurable.
The default (AGG) renderer does not support the TRANSPARENT parameter. It is supported by the GD renderer (GIF).
