示例1: BitmapPalette
int width = 128;
int height = width;
int stride = width/8;
byte[] pixels = new byte[height*stride];
// Try creating a new image with a custom palette.
List<System.Windows.Media.Color> colors = new List<System.Windows.Media.Color>();
colors.Add(System.Windows.Media.Colors.Red);
colors.Add(System.Windows.Media.Colors.Blue);
colors.Add(System.Windows.Media.Colors.Green);
BitmapPalette myPalette = new BitmapPalette(colors);
// Creates a new empty image with the pre-defined palette
BitmapSource image = BitmapSource.Create(
width,
height,
96,
96,
PixelFormats.Indexed1,
myPalette,
pixels,
stride);
FileStream stream = new FileStream("empty.tif", FileMode.Create);
TiffBitmapEncoder encoder = new TiffBitmapEncoder();
TextBlock myTextBlock = new TextBlock();
myTextBlock.Text = "Codec Author is: " + encoder.CodecInfo.Author.ToString();
encoder.Frames.Add(BitmapFrame.Create(image));
MessageBox.Show(myPalette.Colors.Count.ToString());
encoder.Save(stream);
示例2: BitmapImage
// Get the palette from an image
BitmapImage image2 = new BitmapImage();
image2.BeginInit();
image2.UriSource = new Uri("tulipfarm.tif", UriKind.RelativeOrAbsolute);
image2.EndInit();
BitmapPalette myPalette3 = new BitmapPalette(image2, 256);
//Draw the third Image
Image myImage2 = new Image();
myImage2.Source = image2;
myImage2.Stretch = Stretch.None;
myImage2.Margin = new Thickness(20);
