Открытые методы

Метод	Описание
ArrayMinMax ( IList a, double &min, double &max ) : bool	Returns the minimum and maximum values in an IList. The members of the list can be of different types - any type for which the function Utils.ConvertToDouble knows how to convert into a double.
Distance ( PointF a, PointF b ) : float	Calculate the distance between two points, a and b.
Distance ( Point a, Point b ) : int	Calculate the distance between two points, a and b.
DoubleEqual ( double a, double b ) : bool	Returns true if the absolute difference between parameters is less than Epsilon
ScaleFont ( Font initial, double scale ) : Font	Get a Font exactly the same as the passed in one, except for scale factor.
Swap ( double &a, double &b ) : void	Swaps the value of two doubles.
UnitVector ( PointF a, PointF b ) : PointF	Returns unit vector along the line a->b.

Описание методов

ArrayMinMax() публичный статический Метод

Returns the minimum and maximum values in an IList. The members of the list can be of different types - any type for which the function Utils.ConvertToDouble knows how to convert into a double.

public static ArrayMinMax ( IList a, double &min, double &max ) : bool
a	IList	The IList to search.
min	double	The minimum value.
max	double	The maximum value.
Результат	bool

Distance() публичный статический Метод

Calculate the distance between two points, a and b.

public static Distance ( PointF a, PointF b ) : float
a	System.Drawing.PointF	First point
b	System.Drawing.PointF	Second point
Результат	float

Distance() публичный статический Метод

Calculate the distance between two points, a and b.

public static Distance ( Point a, Point b ) : int
a	Point	First point
b	Point	Second point
Результат	int

DoubleEqual() публичный статический Метод

Returns true if the absolute difference between parameters is less than Epsilon

public static DoubleEqual ( double a, double b ) : bool
a	double	first number to compare
b	double	second number to compare
Результат	bool

ScaleFont() публичный статический Метод

Get a Font exactly the same as the passed in one, except for scale factor.

public static ScaleFont ( Font initial, double scale ) : Font
initial	System.Drawing.Font	The font to scale.
scale	double	Scale by this factor.
Результат	System.Drawing.Font

Swap() публичный статический Метод

Swaps the value of two doubles.

public static Swap ( double &a, double &b ) : void
a	double	first value to swap.
b	double	second value to swap.
Результат	void

UnitVector() публичный статический Метод

Returns unit vector along the line a->b.

public static UnitVector ( PointF a, PointF b ) : PointF
a	System.Drawing.PointF	line start point.
b	System.Drawing.PointF	line end point.
Результат	System.Drawing.PointF
