double StelUtils::dmsStrToRad ( const QString & s )

Convert a dms formatted string to an angle in radian.

Parameters:

dsm	The input string

double StelUtils::dmsToRad	(	int	d,
		unsigned int	m,
		double	s
	)

Convert an angle in +-dms format to radian.

Parameters:

d	degree component
m	arcmin component
s	arcsec component

Returns:: angle in radian

bool StelUtils::getDateTimeFromISO8601String	(	const QString &	iso8601Date,
		int *	y,
		int *	m,
		int *	d,
		int *	h,
		int *	min,
		float *	s
	)

Parse an ISO8601 date string.

double StelUtils::getDecAngle ( const QString & str )

Convert a string longitude, latitude, RA or Declination angle to radians.

Parameters:

str	the angle in format something like these: +53d 51'21.6" - +53d51'21.6" -1d 10'31.8" - +46d6'31" 50D46'0"N - 123D47'59"W 123.567 N 123.567W -123.567 12h 14m 6s The degree separator may be a degree symbol (\xBA) in addition to a 'd' or 'D'.

Returns:: the angle in radians. Latitude: North are positive, South are negative. Longitude: East is positive, West is negative. Note: if there is a N, S, E or W suffix, any leading + or - characters are ignored.

double StelUtils::getJDFromSystem ( )

Get the current Julian Date from system time.

Returns:: the current Julian Date

double StelUtils::getJulianDayFromISO8601String	(	const QString &	iso8601Date,
		bool *	ok
	)

Return the Julian Date matching the ISO8601 date string.

Also handles negative and distant years.

double StelUtils::hmsToRad	(	unsigned int	h,
		unsigned int	m,
		double	s
	)

Convert an angle in hms format to radian.

Parameters:

h	hour component
m	minute component
s	second component

Returns:: angle in radian

Vec3f StelUtils::htmlColorToVec3f ( const QString & c )

Converts a color in HTML notation to a Vec3f.

Parameters:

c	The HTML spec color string

QDateTime StelUtils::jdToQDateTime ( const double & jd )

Convert a julian day to a QDateTime.

Parameters:

jd	to convert

Returns:: the matching UTC QDateTime

QString StelUtils::julianDayToISO8601String ( double jd )

Format the given Julian Day in (UTC) ISO8601 date string.

Also handles negative and distant years.

QString StelUtils::localeDateString	(	int	year,
		int	month,
		int	day,
		int	dayOfWeek,
		QString	fmt
	)

Format the date and day-of-week per the format in fmt (see QDateTime::toString()).

Returns:: QString representing the formatted date

QString StelUtils::localeDateString	(	int	year,
		int	month,
		int	day,
		int	dayOfWeek
	)

Format the date and day-of-week per the default locale's QLocale::ShortFormat.

Returns:: QString representing the formatted date

double StelUtils::qDateTimeToJd ( const QDateTime & dateTime )

Convert a QT QDateTime class to julian day.

Parameters:

dateTime the UTC QDateTime to convert

Returns:: the matching decimal Julian Day

double StelUtils::qTimeToJDFraction ( const QTime & time )

Convert a time of day to the fraction of a Julian Day.

Note that a Julian Day starts at 12:00, not 0:00, and so 12:00 == 0.0 and 0:00 == 0.5

void StelUtils::radToDms	(	double	rad,
		bool &	sign,
		unsigned int &	d,
		unsigned int &	m,
		double &	s
	)

Convert an angle in radian to +-dms format.

Parameters:

rad	input angle in radian
sign	true if positive, false otherwise
d	degree component

decimal	output decimal second value

QString StelUtils::radToDmsStrAdapt	(	double	angle,
		bool	useD = `false`
	)

Convert an angle in radian to a dms formatted string.

If the second, minute part is == 0, it is not output

Parameters:
