ANNSMARTDISTANCE

Summary

The ANNSMARTDISTANCE contains information about the unit to be used for a ruler.

Syntax

Copied to clipboard
typedef struct tagANNSMARTDISTANCE 
{ 
   L_UINT uStructSize; 
   L_DOUBLE dDistance; 
   L_UINT uRulerUnit; 
   L_UINT uSmartUnit; 
} ANNSMARTDISTANCE, *pANNSMARTDISTANCE; 

Members

uStructSize

Size of this structure. Use sizeof(ANNSMARTDISTANCE)

dDistance

Distance in appropriate units. The field uSmartUnit identifies the unit.

uRulerUnit

Value that specifies the type of measurement. Can be any one of the following constants:

Value Meaning
ANNUNIT_INCHES [0] Inches.
ANNUNIT_FEET [1] Feet.
ANNUNIT_YARDS [2] Yards.
ANNUNIT_MICROMETERS [3] Micrometers.
ANNUNIT_MILLIMETERS [4] Millimeters.
ANNUNIT_CENTIMETERS [5] Centimeters.
ANNUNIT_METERS [6] Meters.
ANNUNIT_TWIPS [7] Twips.
ANNUNIT_POINTS [8] Points.
ANNUNIT_PIXELS [9] Pixels.
ANNUNIT_SMART_METRIC [10] Smart Metric.
ANNUNIT_SMART_ENGLISH [11] Smart English.

If 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.

uSmartUnit

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.

Comments

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.
