17.18.80 ST_SignedHpsMeasure

This simple type specifies that its contents contain either:

• A positive or negative whole number, whose contents consist of a measurement in half-points
• (equivalent to 1/144th of an inch).
• A positive or negative number followed immediately by a unit identifier.

The contents of this measurement are interpreted based on the context of the parent XML element.

[Example: Consider an attribute value of -72 whose type is ST_SignedHpsMeasure. This attribute value specifies a size of negative one-half of an inch or -36 points (-72 halves of a point = -36 points = -0.5 inches). end example]

[Example: Consider an attribute value of -12.7mm whose type is ST_SignedHpsMeasure. This attribute value specifies a size of -0.0127 meter or negative one-half of an inch or -36 points. end example]

This simple type is a union of the following types:

• The ST_UniversalMeasure simple type (22.9.2.15).
