Public Methods

Method	Description
ApplyGamma ( this source, double gamma ) : Color	Gamma shifts a color by a given amount
FlipEvenColumns ( this pixels, int pixelsPerColumn ) : List	Flips alternating columns of colors in an image
Get21BitPixelBytes ( this colors ) : IEnumerable	Converts an IEnumerable of colors into an IEnumerable of bytes
GetHue ( this color ) : float	Gets the hue as a 0-360 value, representing the degree of rotation
GetIntensity ( this color ) : float	Gets the HSI intensity of the color
GetSaturation ( this color ) : float	Gets the HSI saturation of the color
To21BitPixelBytes ( this color ) : IEnumerable	Extension method for converting a color to three 7-bit bytes
ToColorList ( this bitmap ) : List	Gets a list of all the pixels in a bitmap, serialized to a flat list
ToPerceptual ( this source ) : Color	Shifts a color's intensity so that it looks perceptually correct when displayed on RGB leds.

Method	Description
ApplyGammaToChannel ( byte value, double gamma ) : byte	Applies a gamma shift to a byte value
PerceptualTransformA ( double hue, float saturation, float intensity ) : byte	Transform one of three for converting a HSI-based color to a perceptually adjusted RGB value
PerceptualTransformB ( double hue, float saturation, float intensity ) : byte	Transform two of three for converting a HSI-based color to a perceptually adjusted RGB value
PerceptualTransformC ( double hue, float saturation, float intensity ) : byte	Transform three of three for converting a HSI-based color to a perceptually adjusted RGB value
