#include "ltwrappr.h"

virtual L_INT LAnnProtractor::SetProtractorOptions(bAcute=TRUE, uUnit=ANNANGLE_DEGREES, pszAbbrev=NULL, uPrecision=2, dArcRadius=30, uFlags=0)

L_BOOL bAcute;	flag that indicates which angle to set
L_UINT uUnit;	flag that indicates the units of the angle
L_TCHAR * pszAbbrev;	address of the character string containing the unit abbreviation string
L_UINT uPrecision;	number of digits after the decimal
L_DOUBLE dArcRadius;	length of the arc radius
L_UINT uFlags;	flag that determine which objects to process

Sets various options for a Protractor object.

Parameter	Description
bAcute	Flag that indicates whether to draw the inside (acute or <180 degrees) angle or the outside (obtuse or >180 degrees) angle of the protractor. Possible values are:
	Value	Meaning
	TRUE	Draw the inside (acute) angle of the protractor.
	FALSE	Draw the outside (obtuse) angle of the protractor.

uUnit	Flag that indicates the units of the angle. Possible values are:
	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.
