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
