1. Syntax

Next: Notes  

ANTIALIAS [true|false]

Should TrueType fonts be antialiased.

CHARACTER [char]

Character used to reference a particular TrueType font character. You'll need to figure out the mapping from the keyboard character to font character.

FILLED [true|false]

Sets the symbol to be filled with a user defined color (See the CLASS object). For marker symbols, if OUTLINECOLOR was specified then the symbol is outlined with it.

FONT [string]

Name of TrueType font to use as defined in the FONTSET.

GAP [int]

Given in pixels. This defines a distance between symbols for TrueType lines. As of MapServer 5.0 this also applies to PixMap symbols.

When drawing the symbol along a line segment, a negative GAP will will add 180 degress to the angle. The TrueType and PixMap symbols are always oriented along the line. A GAP of 0 (the default value) will cause MapServer to use the symbol as a brush to draw the line.

IMAGE [string]

Image (GIF or PNG) to use as a marker or brush for type PIXMAP symbols.

NAME [string]

Alias for this font to be used in CLASS objects

LINECAP [butt|round|square|triangle]

Sets the line cap type for the cartoline symbol. Default is butt. Works with the CARTOLINE symbol only!

LINEJOIN [round|miter|bevel]

Sets the line join type for the cartoline symbol. Default is "none" - lines will not be joined . Works with the CARTOLINE symbol only!

LINEJOINMAXSIZE [int]

Sets the max length of the miter line join type. The value represents a coefficient which multiplies a current symbol size. Default is 3. Works with the CARTOLINE symbol only!

PATTERN [num on] [num off] [num on] ... END

Defines a dash style or pattern. Implemented in MapServer 5.0, to replace the deprecated STYLE parameter.

POINTS [x y] [x y] ... END

Signifies the start of the definition of points that make up a vector symbol or that define the x and y radius of an ellipse symbol. The end of this section is signified with the keyword END. Coordinates are given in pixels and define the default size of the symbol before any scaling. You can create non-contiguous paths by inserting negative coordinates at the appropriate place. For ellipse symbols you provide a single point that defines the x and y radius of an ellipse. Circles are created when x and y are equal.

Note:

If a class 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.

STYLE [num on] [num off] [num on] ... END -deprecated

Since MapServer 5.0 the proper parameter to use is PATTERN instead. The deprecated STYLE parameter defines a dash style or pattern.

TRANSPARENT [color index]

Sets a transparent color for the input GIF 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.

TYPE [vector|ellipse|pixmap|truetype|simple|cartoline|hatch]

• vector: a simple drawing is used to define the shape of the symbol.
• ellipse: radius values in the x and y directions define an ellipse.
• pixmap: a user supplied GIF image will be used as the symbol.
• truetype: TrueType font to use as defined in the FONTSET.
• cartoline: allows for different designs of line ends (mitered, rounded, beveled). More information can be found in the Cartographic Symbols document.
• hatch: produces hatched lines throughout the shape.
