POINT Element

Overview

POINT
Specifies the point greeking thresholds.
color optional
Specifies the default greeking color for point geometry.
greeking optional Restriction of xs:string
Flag that determines whether point geometry will be greeked.
threshold1 optional Restriction of xs:int
Not used. Point greeking is either on or off.
threshold2 optional Restriction of xs:int
Not used. Point greeking is either on or off.
threshold3 optional Restriction of xs:int
Not used. Point greeking is either on or off.
threshold4 optional Restriction of xs:int
Not used. Point greeking is either on or off.

Remarks

  • When parent element is PREFERENCES:
  • Each threshold is slower to draw than the one before (that is, 1 is the fastest greeking drawing style and 4 is the slowest greeking drawing style).
  • Above the highest threshold used for points, the actual point symbol will be drawn.
  • The greeking thresholds are in screen pixel units. The extents of each feature in screen pixels is checked against the threshold values. The lowest threshold that the pixel extent falls below will be used to determine the greeking drawing method applied.
  • A threshold with the value 0 will not be used.

Examples

Restrictions

When parent element is PREFERENCES:

  • Each threshold must have a greater value than the one before for greeking to work properly (for example, if threshold1 is 2, then threshold2 must be 3 or greater).
