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.

No code example is currently available or this language may not be supported.

The following example demonstrates how to retrieve a BitmapPalette from an image.
