Attribute Descriptions for NORTHARROW:

Attribute	Usage	Back to Top
angle	1 Angle of the north arrow in degrees. 0 degrees points to the north, and values increase moving clockwise.
antialiasing	2 Used to make edges of labels and symbols smoother. When set to "true", antialiasing is active. Note that the time to generate a map may significantly increase when antialiasing is turned on.
coords	3 North arrow placement location. Coordinate pair is separated by white space by default. The separator can be changed by using SEPARATORS. If using pixel coordinates, "0 0" is in the lower left corner of the map viewer area.
outline	4 Outline color using RGB values.
overlap	5 Determines if labels can overlap this symbol. When "true", labels can overlap. When "false", labels will not overlap the symbol. If labels are not drawing as expected, check if overlap is set to "false" for this symbol or any other symbol in the ArcIMS service.
shadow	6 Shadow color using RGB values.
size	7 Arrow size in pixels.
transparency	8 Value to set percentage of transparency. 1.0 is 0 percent transparent. 0.0 is 100 percent transparent.
type	9 Value representing north arrow type.
