SyntaxThe RGB type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | RGB(Color) |
Initializes a new instance of the RGB class.
|
| RGB(Byte, Byte, Byte) |
Initializes a new instance of the RGB class.
|
| RGB(Byte, Byte, Byte, Byte) |
Initializes a new instance of the RGB class.

Properties
Methods| Name | Description | |
|---|---|---|
| Equals | Indicates whether this instance and a specified object are equal. (Inherited from ValueType.) |
| GetHashCode | Returns the hash code for this instance. (Inherited from ValueType.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| ToString | Returns the fully qualified type name of this instance. (Inherited from ValueType.) |
Operators| Name | Description | |
|---|---|---|
  | (RGB to HSL) |
Performs an explicit conversion from RGB to HSL.
|
| (RGB to YCbCr) |
Performs an explicit conversion from RGB to YCbCr.
|
Fields| Name | Description | |
|---|---|---|
 | A |
Index of alpha component for ARGB images.
|
| Alpha |
Alpha component.
|
| B |
Index of blue component.
|
| Blue |
Blue component.
|
| G |
Index of green component.
|
| Green |
Green component.
|
| R |
Index of red component.
|
| Red |

|
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.) |
RemarksThe class encapsulates RGB color components and can be used to implement logic for reading, writing and converting to and from RGB color representations.

| The PixelFormat.Format24bppRgb actually refers to a BGR pixel format. |
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;
