Methods

CalculateGradient(Color, Color, double)

Calculate gradient from color to the other with amount given as pecents. Each channel is calculated separately and changed with channgel difference multiplied by the defined factor.

public static Color CalculateGradient(this Color colorFrom, Color colorTo, double positionPercents)

Parameters

colorFrom Color

Source color to start from.

colorTo Color

Destination color to move towards.

positionPercents double

Factor to move by, as percents. Negative and values over 100 are valid, though channel values are capped to between [0, 255].

Color

Resulting color

CopyItems(Array, Array, int)

Copy array

public static void CopyItems(this Array array, Array destination, int length)

Parameters

array Array

destination Array

length int

DisposeAllAndClear<T>(List<T>)

Disposes all items in the given list, and clears the list.

Note that the list must NOT change because of the dispose. For those situations use DisposeAllThroughCopyAndClear instead.

public static void DisposeAllAndClear<T>(this List<T> list) where T : IDisposable

Parameters

list List<T>

Type Parameters

T

DisposeAllThroughCopyAndClear<T>(List<T>)

Disposes all items in the given list by first taking a copy of the list.

This is intended only for situations where the dispose change original list contents. It's preferable to use DisposeAllAndClear instead.

public static void DisposeAllThroughCopyAndClear<T>(this List<T> list) where T : IDisposable

Parameters

list List<T>

Type Parameters

T

DistanceSquareTo(PointDouble2D, PointDouble2D)

public static double DistanceSquareTo(this PointDouble2D from, PointDouble2D dest)

Parameters

from PointDouble2D

dest PointDouble2D

Returns

double

DistanceSquareTo(PointFloat, PointFloat)

Square distance between two points

public static double DistanceSquareTo(this PointFloat from, PointFloat dest)

Parameters

from PointFloat

dest PointFloat

Returns

double

GatherApplicationInformation(LightningChart, GatherDataOptions, string, string)
