Provides reusable adjustment methods to apply to images.

Méthodes publiques

Méthode	Description
Alpha ( Image source, int percentage, Rectangle rectangle = null ) : Bitmap	Adjusts the alpha component of the given image.
Brightness ( Image source, int threshold, Rectangle rectangle = null ) : Bitmap	Adjusts the brightness component of the given image.
Contrast ( Image source, int threshold, Rectangle rectangle = null ) : Bitmap	Adjusts the contrast component of the given image.
Gamma ( Image source, float value ) : Bitmap	Adjust the gamma (intensity of the light) component of the given image.
ToLinear ( Image source ) : Bitmap	Converts an image from an sRGB color-space to the equivalent linear color-space.
ToSRGB ( Image source ) : Bitmap	Converts an image from a linear color-space to the equivalent sRGB color-space.

Méthode	Description
GetLinearBytes ( ) : byte[]	Gets an array of bytes representing each possible value of color component converted from sRGB to the linear color space.
GetSRGBBytes ( ) : byte[]	Gets an array of bytes representing each possible value of color component converted from linear to the sRGB color space.
LinearToSRGB ( float signal ) : float	Gets the correct sRGB value from an linear signal.
SRGBToLinear ( float signal ) : float	Gets the correct linear value from an sRGB signal.

Adjusts the alpha component of the given image.

/// Thrown if the percentage value falls outside the acceptable range. ///

public static Alpha ( Image source, int percentage, Rectangle rectangle = null ) : Bitmap
source	Image	/// The source to adjust. ///
percentage	int	/// The percentage value between 0 and 100 for adjusting the opacity. ///
rectangle	System.Drawing.Rectangle	The rectangle to define the bounds of the area to adjust the opacity. /// If null then the effect is applied to the entire image.
Résultat	System.Drawing.Bitmap

Adjusts the brightness component of the given image.

/// Thrown if the threshold value falls outside the acceptable range. ///

public static Brightness ( Image source, int threshold, Rectangle rectangle = null ) : Bitmap
source	Image	/// The source to adjust. ///
threshold	int	/// The threshold value between -100 and 100 for adjusting the brightness. ///
rectangle	System.Drawing.Rectangle	The rectangle to define the bounds of the area to adjust the brightness. /// If null then the effect is applied to the entire image.
Résultat	System.Drawing.Bitmap

Adjusts the contrast component of the given image.

/// Thrown if the threshold value falls outside the acceptable range. ///

public static Contrast ( Image source, int threshold, Rectangle rectangle = null ) : Bitmap
source	Image	/// The source to adjust. ///
threshold	int	/// The threshold value between -100 and 100 for adjusting the contrast. ///
rectangle	System.Drawing.Rectangle	The rectangle to define the bounds of the area to adjust the contrast. /// If null then the effect is applied to the entire image.
Résultat	System.Drawing.Bitmap

Adjust the gamma (intensity of the light) component of the given image.

/// Thrown if the value falls outside the acceptable range. ///

public static Gamma ( Image source, float value ) : Bitmap
source	Image	/// The source to adjust. ///
value	float	/// The value to adjust the gamma by (typically between .2 and 5). ///
Résultat	System.Drawing.Bitmap
