BitmapPalette Class
Defines the available color palette for a supported image type.
System.Windows.Threading::DispatcherObject
System.Windows.Media.Imaging::BitmapPalette
Assembly: PresentationCore (in PresentationCore.dll)
The BitmapPalette type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | BitmapPalette(IList<Color>) | Initializes a new instance of the BitmapPalette class with the specified colors. |
![]() | BitmapPalette(BitmapSource, Int32) | Initializes a new instance of the BitmapPalette class based on the specified BitmapSource. The new BitmapPalette is limited to a specified maximum color count. |
| Name | Description | |
|---|---|---|
![]() | Colors | Get the colors defined in a palette. |
![]() | Dispatcher | Gets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject.) |
| Name | Description | |
|---|---|---|
![]() | CheckAccess | Determines whether the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.) |
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
![]() | VerifyAccess | Enforces that the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.) |
Only Tagged Image File Format (TIFF) and Graphics Interchange Format (GIF) image formats support image palettes. However, other image types can be used to define a BitmapPalette. Attempting to define a BitmapPalette for an unsupported bitmap format does not result in an exception; the designated BitmapPalette is simply ignored.
Windows Presentation Foundation (WPF) supports both custom color palettes and predefined palettes defined by the BitmapPalettes class.
The following example demonstrates how to define a custom BitmapPalette and apply it to a new BitmapSource.
The following example demonstrates how to retrieve a BitmapPalette from an image.
