ImagingUtil

Configuration

ConfigInterpolationMode

The configurator object for InterpolationMode values.

public static readonly field	ConfigInterpolationMode
type	IConfigurator<InterpolationMode>

ConfigPixelChannel

The configurator object for PixelChannel values.

public static readonly field	ConfigPixelChannel
type	IConfigurator<PixelChannel>

ConfigPixelCoverage

The configurator object for PixelCoverage values.

public static readonly field	ConfigPixelCoverage
type	IConfigurator<PixelCoverage>

ConfigPixelFormat

The configurator object for PixelFormat values.

public static readonly field	ConfigPixelFormat
type	IConfigurator<PixelFormat>

Public / Constants

GammaFromSrgb

Special gamma correction value for the sRGB color space (see Gamma).

public constant	GammaFromSrgb = -2.2
type	float64

Remarks:

Color space decompression for sRGB can be approximated with the exponent 2.2. The full formula is implemented in FromSrgbF.

GammaToSrgb

Special gamma correction value for the sRGB color space (see Gamma).

public constant	GammaToSrgb = -0.45455
type	float64

Remarks:

This is the same value that is found in the gAMA chunk of sRGB compressed PNG files.

Public / Methods

BadFormat

The binary format of an image file format is invalid and cannot be read.

[Pure]
public static method	BadFormat (string source, string format, IPathInfo path, string message = null)
type	IOException
params	source		Error source tag.
	format	[not-empty]	The file format name.
	path	[not-null]	The path info object.
	message		Optional error message. Defaults to null.
returns			The ready-to-throw exception.

BytesPerPixel

Returns the number of bytes per pixel for the given pixel format.

[Pure]
public static method	BytesPerPixel (PixelFormat pixelFormat)
type	int32
params	pixelFormat		The pixel format.
returns		[>0]	The number of bytes per pixel.

GammaMul

Multiplies the given gamma correction values (see Gamma), as would be done with pure exponents.

[Pure]
public static method	GammaMul (float64 a, float64 b)
type	float64
params	a		First gamma correction value.
	b		Second gamma correction value.
returns			The resulting gamma correction value.

GammaRcp

Returns the reciprocal of the given gamma correction value (see Gamma), as would be done with a pure exponent.

[Pure]
public static method	GammaRcp (float64 a)
type	float64
params	a		The gamma correction value.
returns			The resulting gamma correction value.

MapInfoFor

Returns a MapInfo value for the given image info.

public static method	MapInfoFor (IImageInfo info)
type	MapInfo
params	info	[not-null]	The image info.
returns			The MapInfo value.

PixelFormatOf

Returns the pixel format of the given color.

[Pure]
public static method	PixelFormatOf (int64 color)
type	PixelFormat
params	color		The color value (see Colors).
returns			The pixel format.

PixelFormatUnion

Combines the union of the given pixel formats.

[Pure]
public static method	PixelFormatUnion (PixelFormat a, PixelFormat b)
type	PixelFormat
params	a		First pixel format.
	b		Second pixel format.
returns			The combined pixel format that can represent pixels in both of the given formats, without loss of data.

SamplesPerPixel

Returns the number of samples per pixel for the given pixel format.

[Pure]
public static method	SamplesPerPixel (PixelFormat pixelFormat)
type	int32
params	pixelFormat		The pixel format.
returns		[>0]	The number of samples per pixel.
