Syntax[ObsoleteAttribute("Use Grayscale.CommonAlgorithms.Y object instead")] public sealed class GrayscaleY : Grayscale
The GrayscaleY type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | GrayscaleY |
Initializes a new instance of the GrayscaleY class.
|
Properties| Name | Description | |
|---|---|---|
 | FormatTranslations |
Format translations dictionary.
(Inherited from Grayscale.) |
Methods| Name | Description | |
|---|---|---|
| Apply(Bitmap) |
Apply filter to an image.
(Inherited from BaseFilter.) |
| Apply(BitmapData) |
Apply filter to an image.
(Inherited from BaseFilter.) |
| Apply(UnmanagedImage) |
Apply filter to an image in unmanaged memory.
(Inherited from BaseFilter.) |
| Apply(UnmanagedImage, UnmanagedImage) |
Apply filter to an image in unmanaged memory.
(Inherited from BaseFilter.) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Fields| Name | Description | |
|---|---|---|
 | BlueCoefficient |
Portion of blue channel's value to use during conversion from RGB to grayscale.
(Inherited from Grayscale.) |
| GreenCoefficient |
Portion of green channel's value to use during conversion from RGB to grayscale.
(Inherited from Grayscale.) |
| RedCoefficient |
Portion of red channel's value to use during conversion from RGB to grayscale.

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.

RemarksThe class uses Y algorithm to convert color image
to grayscale. The conversion coefficients are:
- Red: 0.299;
- Green: 0.587;
- Blue: 0.114.
