Example 1. Dashed Line¶
This example creates a dashed line that is 5 SIZEUNITS wide, with 10 SIZEUNITS on, 5 off, 5 on, 10 off …

Example 2. TrueType font marker symbol¶
This example symbol is a star, used to represent the national capital, hence the name. The font name in defined in the FONTSET file. The code number „114“ varies, you can use MS Windows‘ character map to figure it out, or guestimate.
SYMBOL
NAME "natcap"
TYPE TRUETYPE
FONT "geo"
FILLED true
ANTIALIAS true # only necessary for GD rendering
CHARACTER "r"
END
Example 3. Vector triangle marker symbol¶
This example is fairly straight forward. Note that to have 3 sides you need 4 points, hence the first and last points are identical. The triangle is not filled.
SYMBOL
NAME "triangle"
TYPE vector
POINTS
0 4
2 0
4 4
0 4
END
END
Example 4. Non-contiguous vector marker symbol (Cross)¶
This example draws a cross, that is 2 lines (vectors) that are not connected end-to-end (Like the triangle in the previous example). The negative values separate the two.
SYMBOL
NAME "cross"
TYPE vector
POINTS
2.0 0.0
2.0 4.0
-99 -99
0.0 2.0
4.0 2.0
END
END
Example 5. Circle vector symbol¶
This example creates a simple filled circle. Using non-equal values for the point will give you an actual ellipse.
SYMBOL
NAME "circle"
TYPE ellipse
FILLED true
POINTS
1 1
END
END
Example 6. Downward diagonal fill¶
This example creates a symbol that can be used to create a downward diagonal fill for polygons.
SYMBOL
NAME "downwarddiagonalfill"
TYPE vector
TRANSPARENT 0
POINTS
0 1
1 0
END
END
Example 7. Using the Symbol Type HATCH (new in 4.6)¶
As of MapServer 4.6, you can use the symbol type HATCH to produce hatched lines. The following will display hatched lines at a 45 degree angle, 10 SIZEUNITS apart (center to center), and 3 SIZEUNITS wide.
Symbol definition:
SYMBOL
NAME 'hatch-test'
TYPE HATCH

WIDTH 3
END
END
END
Other parameters available for HATCH are: MINSIZE, MAXSIZE, MINWIDTH, and MAXWIDTH.
Example 8. Styled lines using GAP¶
This example shows how to style lines with symbols.
A 5 SIZEUNITS wide black line is decorated with ellipses that are 15 SIZEUNITS long (and 7.5 SIZEUNITS`wide). The ellipses are placed 30 `SIZEUNITS apart, and the negative GAP value ensures that the ellipses are oriented relative to the direction of the line. The ellipses are rotated 30 degrees counter clock-wise from their position along the line.

TYPE ellipse

POINTS
