The ANNSMARTDISTANCE contains information about the unit to be used for a ruler.
Size of this structure. Use sizeof(ANNSMARTDISTANCE)
Distance in appropriate units. The field
uSmartUnit identifies the unit.
Value that specifies the type of measurement. Can be any one of the following constants:
|ANNUNIT_SMART_METRIC|| Smart Metric.|
|ANNUNIT_SMART_ENGLISH|| Smart English.|
uRulerUnit is ANNUNIT_SMART_METRIC or ANNUNIT_SMART_ENGLISH, then the actual units can be found in the
uSmartUnit member. If
uRulerUnit is not one ANNUNIT_SMART_METRIC or ANNUNIT_SMART_ENGLISH, then
uRulerUnit contains the unit constant.
Value that specifies the base unit of measure. Always contains the unit constant. This can be any of the ANNUNIT_XXX constants EXCEPT ANNUNIT_SMART_METRIC or ANNUNIT_SMART_ENGLISH.
A "smart unit" is a unit that can be automatically promoted to the next higher unit. For example, suppose you have a ruler that is 13 inches long. If the units of the ruler are ANNUNIT_INCHES, then the length is 13. However, if the units of the ruler are ANNUNIT_SMART_ENGLISH, then the length of the ruler is automatically promoted to feet. The length in this case would be 1.0833 feet.
