Examples

The following examples show how to decode and encode a Tagged Image File Format (TIFF) image using the specific TiffBitmapDecoder and TiffBitmapEncoder objects. For the complete sample, see TIFF Encoder and Decoder Sample

This example demonstrates how to decode a TIFF image using a TiffBitmapDecoder from a Uri.

Visual Basic
' Open a Stream and decode a TIFF image
Dim imageStreamSource As New FileStream("tulipfarm.tif", FileMode.Open, FileAccess.Read, FileShare.Read)
Dim decoder As New TiffBitmapDecoder(imageStreamSource, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default)
Dim bitmapSource As BitmapSource = decoder.Frames(0)

' Draw the Image
Dim myImage As New Image()
myImage.Source = bitmapSource
myImage.Stretch = Stretch.None
myImage.Margin = New Thickness(20)
C#
// Open a Stream and decode a TIFF image
Stream imageStreamSource = new FileStream("tulipfarm.tif", FileMode.Open, FileAccess.Read, FileShare.Read);
TiffBitmapDecoder decoder = new TiffBitmapDecoder(imageStreamSource, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);
BitmapSource bitmapSource = decoder.Frames[0];

// Draw the Image
Image myImage = new Image();
myImage.Source = bitmapSource;
myImage.Stretch = Stretch.None;
myImage.Margin = new Thickness(20);
Visual C++
// Open a Stream and decode a TIFF image
Stream^ imageStreamSource = gcnew FileStream("tulipfarm.tif", FileMode::Open, FileAccess::Read, FileShare::Read);
TiffBitmapDecoder^ decoder = gcnew TiffBitmapDecoder(imageStreamSource, BitmapCreateOptions::PreservePixelFormat, BitmapCacheOption::Default);
BitmapSource^ bitmapSource = decoder->Frames[0];

// Draw the Image
Image^ myImage = gcnew Image();
myImage->Source = bitmapSource;
myImage->Stretch = Stretch::None;
myImage->Margin = System::Windows::Thickness(20);

This example demonstrates how to encode a BitmapSource into a TIFF image using a TiffBitmapEncoder.

Visual Basic
Dim width As Integer = 128
Dim height As Integer = width
Dim stride As Integer = CType(width / 8, Integer)
Dim pixels(height * stride) As Byte

' Define the image palette
Dim myPalette As BitmapPalette = BitmapPalettes.WebPalette

' Creates a new empty image with the pre-defined palette
Dim image As BitmapSource = System.Windows.Media.Imaging.BitmapSource.Create( _
    width, height, 96, 96, PixelFormats.Indexed1, myPalette, pixels, stride)
Dim stream As New FileStream("new.tif", FileMode.Create)
Dim encoder As New TiffBitmapEncoder()
Dim myTextBlock As New TextBlock()
myTextBlock.Text = "Codec Author is: " + encoder.CodecInfo.Author.ToString()
encoder.Compression = TiffCompressOption.Zip
encoder.Frames.Add(BitmapFrame.Create(image))
encoder.Save(stream)
C#
int width = 128;
int height = width;
int stride = width / 8;
byte[] pixels = new byte[height * stride];

// Define the image palette
BitmapPalette myPalette = BitmapPalettes.WebPalette;

// 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.tif", FileMode.Create);
TiffBitmapEncoder encoder = new TiffBitmapEncoder();
TextBlock myTextBlock = new TextBlock();
myTextBlock.Text = "Codec Author is: " + encoder.CodecInfo.Author.ToString();
encoder.Compression = TiffCompressOption.Zip;
encoder.Frames.Add(BitmapFrame.Create(image));
encoder.Save(stream);

Visual C++
int width = 128;
int height = width;
int stride = width / 8;
array<System::Byte>^ pixels = gcnew array<System::Byte>(height * stride);

// Define the image palette
BitmapPalette^ myPalette = BitmapPalettes::WebPalette;

// 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 = gcnew FileStream("new.tif", FileMode::Create);
TiffBitmapEncoder^ encoder = gcnew TiffBitmapEncoder();
TextBlock^ myTextBlock = gcnew TextBlock();
myTextBlock->Text = "Codec Author is: " + encoder->CodecInfo->Author->ToString();
encoder->Compression = TiffCompressOption::Zip;
encoder->Frames->Add(BitmapFrame::Create(image));
encoder->Save(stream);
