|
|
Value |
Meaning |
|
ANNANGLE_DEGREES |
Measure the angle in degrees. The default abbreviation for this unit is the degree sign. |
|
ANNANGLE_RADIANS |
Measure the angle in radians. The default abbreviation for this unit is "rad". |
pszAbbrev |
Character string that contains the abbreviation to be put after the angle. Use NULL to set the default abbreviation for the specified unit. |
|
uPrecision |
The number of digits after the decimal. ( "." ) |
|
dArcRadius |
The arc radius. |
|
uFlags |
Flags that determine which objects to process. You can combine values when appropriate by using a bitwise OR ( | ). The following are valid values: |
|
|
Value |
Meaning |
|
0 |
Process only the specified object. |
|
ANNFLAG_SELECTED |
[0x0001] Process only objects that have the selected property set to TRUE. For getting and setting the selected property, use the LAnnotation::IsSelected and LAnnotation::SetSelected functions. |
|
ANNFLAG_NOINVALIDATE |
[0x0010] Do not invalidate the affected rectangle in the window. Use this to avoid generating unwanted paint messages. |
