Attribute Descriptions for NORTHARROW:

Attribute	Usage	Back to Top
angle	Angle of the northarrow in degrees. 0 degrees points to the north, and values increase moving clockwise.
antialiasing	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	Northarrow 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	Outline color using RGB values.
overlap	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 MapService.
shadow	Shadow color using RGB values.
size	Arrow size in pixels.
transparency	Value to set percentage of transparency. 1.0 is 0 percent transparent. 0.0 is 100 percent transparent.
type	Value representing northarrow type.
