BmpBitmapEncoder Class

Defines an encoder that is used to encode bitmap (BMP) format images.

Namespace: System.Windows.Media.Imaging
Assembly: PresentationCore (in presentationcore.dll)
XML Namespace:  http://schemas.microsoft.com/winfx/2006/xaml/presentation

public sealed class BmpBitmapEncoder : BitmapEncoder
public final class BmpBitmapEncoder extends BitmapEncoder
public final class BmpBitmapEncoder extends BitmapEncoder
<BmpBitmapEncoder .../>

Bitmap (BMP) format does not support features that are supported by other bitmap formats, including global preview, global thumbnail, global metadata, frame level thumbnails, multiple frames, and frame level metadata.

Encoding does not work in partial trust. See the Windows Presentation Foundation Partial Trust Programming topic for information on partial trust.

The following example demonstrates how to use the BmpBitmapEncoder to encode a new bitmap image.

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("new.bmp", FileMode.Create);
BmpBitmapEncoder encoder = new BmpBitmapEncoder();
TextBlock myTextBlock = new TextBlock();
myTextBlock.Text = "Codec Author is: " + encoder.CodecInfo.Author.ToString();
encoder.Frames.Add(BitmapFrame.Create(image));
encoder.Save(stream);
