Cara: Mengodekan dan Mendekode Gambar TIFF

Contoh berikut menunjukkan cara mendekode dan mengodekan gambar Format File Gambar Bertag (TIFF) menggunakan objek TiffBitmapDecoder dan TiffBitmapEncoder tertentu.

Mendekode gambar TIFF

Contoh ini menunjukkan cara mendekode gambar TIFF menggunakan TiffBitmapDecoder dari Uri.

// 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);

// Open a Stream and decode a TIFF image.
Stream imageStreamSource = new FileStream("tulipfarm.tif", FileMode.Open, FileAccess.Read, FileShare.Read);
var decoder = new TiffBitmapDecoder(imageStreamSource, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);
BitmapSource bitmapSource = decoder.Frames[0];

// Draw the Image.
var myImage = new Image();
myImage.Source = bitmapSource;
myImage.Stretch = Stretch.None;
myImage.Margin = new Thickness(20);

' 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)

Mengodekan gambar TIFF

Contoh ini menunjukkan cara mengodekan BitmapSource ke dalam gambar TIFF menggunakan TiffBitmapEncoder.

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);


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);

var stream = new FileStream("new.tif", FileMode.Create);
var encoder = new TiffBitmapEncoder();
var 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);


Dim width As Integer = 128
Dim height As Integer = width
Dim stride As Integer = width / 8
Dim pixels(height * stride - 1) 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 = 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)
