virtual L_INT LAnnProtractor::SetProtractorOptions(bAcute=TRUE, uUnit=ANNANGLE_DEGREES, pszAbbrev=NULL, uPrecision=2, dArcRadius=30, uFlags=0)
Sets various options for a Protractor object.
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:
|TRUE||Draw the inside (acute) angle of the protractor.|
|FALSE||Draw the outside (obtuse) angle of the protractor.|
Flag that indicates the units of the angle. Possible values are:
|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".|
Character string that contains the abbreviation to be put after the angle. Use NULL to set the default abbreviation for the specified unit.
