YCbCr Structure |
YCbCr components.
Namespace: Accord.Imaging
Assembly: Accord.Imaging (in Accord.Imaging.dll) Version: 3.8.0
SyntaxThe YCbCr type exposes the following members.
ConstructorsMethods| Name | Description | |
|---|---|---|
 | Equals | Indicates whether this instance and a specified object are equal. (Inherited from ValueType.) |
 | FromRGB(RGB) |
Convert from RGB to YCbCr color space (Rec 601-1 specification).
|
| FromRGB(RGB, YCbCr) |
Convert from RGB to YCbCr color space (Rec 601-1 specification).
|
| GetHashCode | Returns the hash code for this instance. (Inherited from ValueType.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| ToRGB |
Convert the color to RGB color space.
|
| ToRGB(YCbCr, RGB) |
Convert from YCbCr to RGB color space.
|
| ToString | Returns the fully qualified type name of this instance. (Inherited from ValueType.) |
Operators| Name | Description | |
|---|---|---|
 | (YCbCr to RGB) |
Performs an explicit conversion from YCbCr to RGB.
|
| (YCbCr to HSL) |
Performs an explicit conversion from YCbCr to HSL.
|
Fields| Name | Description | |
|---|---|---|
 | Cb | Cb component.
|
| CbIndex |
Index of Cb component.
|
| Cr | Cr component.
|
| CrIndex |
Index of Cr component.
|
| Y | Y component.
|
| YIndex |
Index of Y component.
|
Extension Methods| Name | Description | |
|---|---|---|
 | HasMethod |
Checks whether an object implements a method with the given name.
(Defined by ExtensionMethods.) |
| IsEqual |
Compares two objects for equality, performing an elementwise
comparison if the elements are vectors or matrices.
(Defined by Matrix.) |
| To(Type) | Overloaded.
Converts an object into another type, irrespective of whether
the conversion can be done at compile time or not. This can be
used to convert generic types to numeric types during runtime.
(Defined by ExtensionMethods.) |
| ToT | Overloaded.
Converts an object into another type, irrespective of whether
the conversion can be done at compile time or not. This can be
used to convert generic types to numeric types during runtime.
(Defined by ExtensionMethods.) |
Remarks
The class encapsulates YCbCr color components and can be used to implement
logic for reading, writing and converting to and from YCbCr color representations.
ExamplesThe following examples show how to convert to and from various pixel representations:
// This example shows how to convert to and from various // pixel representations. For example, let's say we start // with a RGB pixel with the value (24, 250, 153): RGB rgb = new RGB(red: 24, green: 250, blue: 153); // The value of this pixel in HSL format would be: HSL hsl = HSL.FromRGB(rgb); // should be (154, 0.9576271, 0.5372549) // The value of this pixel in YCbCr format would be: YCbCr yCbCr = YCbCr.FromRGB(rgb); // should be (0.671929836, -0.0406815559, -0.412097245) // Note: we can also convert using casting: HSL a = (HSL)rgb; YCbCr b = (YCbCr)rgb;
// This example shows how to convert to and from various // pixel representations. For example, let's say we start // with a HSL pixel with the value (123, 0.4, 0.8): HSL hsl = new HSL(hue: 123, saturation: 0.4f, luminance: 0.8f); // The value of this pixel in RGB format would be: RGB rgb = hsl.ToRGB(); // should be (183, 224, 185) // The value of this pixel in YCbCr format would be: YCbCr yCbCr = YCbCr.FromRGB(rgb); // should be (0.8128612, -0.0493462719, -0.0679121539) // Note: we can also convert using casting: RGB a = (RGB)hsl; YCbCr b = (YCbCr)hsl;
// This example shows how to convert to and from various // pixel representations. For example, let's say we start // with a YCbCr pixel with the value (0.8, 0.2, 0.5): YCbCr yCbCr = new YCbCr(y: 0.8f, cb: 0.2f, cr: 0.5f); // The value of this pixel in RGB format would be: RGB rgb = yCbCr.ToRGB(); // should be (255, 95, 255) // The value of this pixel in HSL format would be: HSL hsl = HSL.FromRGB(rgb); // should be (299, 0.99999994, 0.6862745) // Note: we can also convert using casting: RGB a = (RGB)yCbCr; HSL b = (HSL)yCbCr;
