Gets the options for the specified Protractor object. This function is available in the Document/Medical Toolkits.

Parameter	Description
hObject	Handle to the annotation object.
pbAcute	Address of the variable to be updated with a value that indicates whether the inside angle or the outside angle of the protractor is being drawn. Possible values are:
	Value	Meaning
	TRUE	The inside (acute) angle of the protractor is being drawn.
	FALSE	The outside (obtuse) angle of the protractor is being drawn.
	Pass NULL if you do not wish to retrieve this information.

puUnit	Address of the variable to be updated with a value that indicates whether the units of the angle are degrees or radians. Pass NULL if you do not wish to retrieve this information. The updated values are:
	Value	Meaning
	ANNANGLE_DEGREES	The angle is measured in degrees. The default abbreviation for this unit is the degree sign.
	ANNANGLE_RADIANS	The angle is measured in radians. The default abbreviation for this unit is "rad".
puUnit	Address of the variable to be updated with a value that indicates whether the units of the angle are degrees or radians. Pass NULL if you do not wish to retrieve this information.
puAbbrevLen	Address of the variable to be updated with the length of the abbreviation string that follows the angle. Pass NULL if you do not wish to retrieve this information.
pszAbbrev	Address of the character string to be updated with the abbreviation string that follows the angle. Pass NULL if you do not wish to retrieve this information.
puPrecision	Addresss of the variable to be updated with the number of digits after the decimal. ("." ) Valid values are 0 – 200.
pdArcRadius	Address of the variable to be updated with the length of the arc radius.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

You may wish to call this function once, with pszAbbrev set to NULL, and a pointer for puAbbrevLen. The variable pointed to by puAbbrevLen will contain the length of the abbreviation string. Allocate a buffer of this size and call this function again, passing the newly allocated buffer for pszAbbrev.
