Public Methods

Method	Description
AdjustBrightness ( float brightness ) : void	Changes the brightness. Typical values are in the range [-1, 1]. Values above zero will make the image brighter, values below zero will make it darker.
AdjustContrast ( float contrast ) : void	Changes the contrast. Typical values are in the range [-1, 1]. Values above zero will raise, values below zero will reduce the contrast.
AdjustHue ( float hue ) : void	Changes the hue. Typical values are in the range [-1, 1].
AdjustSaturation ( float saturation ) : void	Changes the saturation. Typical values are in the range [-1, 1]. Values above zero will raise, values below zero will reduce the saturation. '-1' will produce a grayscale image.
ColorMatrix ( float values = null ) : System	Initializes a color matrix with an array of 20 floats. If no value is specified it initializes with an identity matrix.
ConcatColorMatrix ( ColorMatrix colorMatrix ) : void	Concatenates the receiving color matrix with another one.
Identity ( ) : void	Changes the color matrix into an identity matrix.
Invert ( ) : void	Inverts the colors.

Method Details

AdjustBrightness() public method

Changes the brightness. Typical values are in the range [-1, 1]. Values above zero will make the image brighter, values below zero will make it darker.

public AdjustBrightness ( float brightness ) : void
brightness	float
return	void

AdjustContrast() public method

Changes the contrast. Typical values are in the range [-1, 1]. Values above zero will raise, values below zero will reduce the contrast.

public AdjustContrast ( float contrast ) : void
contrast	float
return	void

AdjustHue() public method

Changes the hue. Typical values are in the range [-1, 1].

public AdjustHue ( float hue ) : void
hue	float
return	void

AdjustSaturation() public method

Changes the saturation. Typical values are in the range [-1, 1]. Values above zero will raise, values below zero will reduce the saturation. '-1' will produce a grayscale image.

public AdjustSaturation ( float saturation ) : void
saturation	float
return	void

ColorMatrix() public method

Initializes a color matrix with an array of 20 floats. If no value is specified it initializes with an identity matrix.

public ColorMatrix ( float values = null ) : System
values	float
return	System

ConcatColorMatrix() public method

Concatenates the receiving color matrix with another one.

public ConcatColorMatrix ( ColorMatrix colorMatrix ) : void
colorMatrix	ColorMatrix
return	void

Identity() public method

Changes the color matrix into an identity matrix.

public Identity ( ) : void
return	void

Invert() public method

Inverts the colors.

public Invert ( ) : void
return	void
