This example creates a dashed line that is 5 SIZEUNITS wide, with 10 SIZEUNITS on, 5 off, 5 on, 10 off ...
LAYER ... CLASS ... STYLE COLOR 0 0 0 WIDTH 5 LINECAP butt PATTERN 10 5 5 10 END END END END
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
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
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
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
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
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 NAME 'hatch-test' TYPE HATCH END
LAYER ... CLASS ... STYLE SYMBOL 'hatch-test' COLOR 255 0 0 ANGLE 45 SIZE 10 WIDTH 3 END END END
Other parameters available for HATCH are: MINSIZE, MAXSIZE, MINWIDTH, and MAXWIDTH.
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.
SYMBOL NAME "ellipse2" TYPE ellipse FILLED true POINTS 1 2 END END
LAYER ... CLASS ... STYLE WIDTH 5 COLOR 0 0 0 END STYLE SYMBOL 'ellipse2' COLOR 0 0 0 ANGLE 30 SIZE 15 GAP -30 END END END
