Description |
|
|
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.
