JpegBitmapEncoder.FlipHorizontal Eigenschaft

Definition

Namespace:

System.Windows.Media.Imaging

Assembly:

PresentationCore.dll

Dient zum Abrufen oder Festlegen eines Werts, der angibt, ob ein JPEG-Bild (Joint Photographics Experts Group) horizontal während der Codierung gedreht werden soll.

public:
 property bool FlipHorizontal { bool get(); void set(bool value); };

public bool FlipHorizontal { get; set; }

member this.FlipHorizontal : bool with get, set

Public Property FlipHorizontal As Boolean

Eigenschaftswert

Boolean

true, wenn das Bild während der Codierung horizontal gekippt wird, andernfalls false.

Beispiele

Im folgenden Beispiel wird veranschaulicht, wie der Wert der FlipHorizontal Eigenschaft festgelegt wird.

BitmapSource^ image = BitmapSource::Create(
   width, height,
   96, 96,
   PixelFormats::Indexed1,
   myPalette,
   pixels,
   stride);

BitmapSource image = BitmapSource.Create(
    width,
    height,
    96,
    96,
    PixelFormats.Indexed1,
    myPalette,
    pixels,
    stride);

Dim image As BitmapSource = System.Windows.Media.Imaging.BitmapSource.Create(width, height, 96, 96, PixelFormats.Indexed1, myPalette, pixels, stride)

System::IO::FileStream^ stream = gcnew System::IO::FileStream("new.jpg", FileMode::Create);
JpegBitmapEncoder^ encoder = gcnew JpegBitmapEncoder();
TextBlock^ myTextBlock = gcnew System::Windows::Controls::TextBlock();
myTextBlock->Text = "Codec Author is: " + encoder->CodecInfo->Author->ToString();
encoder->FlipHorizontal = true;
encoder->FlipVertical = false;
encoder->QualityLevel = 30;
encoder->Rotation = Rotation::Rotate90;
encoder->Frames->Add(BitmapFrame::Create(image));
encoder->Save(stream);

FileStream stream = new FileStream("new.jpg", FileMode.Create);
JpegBitmapEncoder encoder = new JpegBitmapEncoder();
TextBlock myTextBlock = new TextBlock();
myTextBlock.Text = "Codec Author is: " + encoder.CodecInfo.Author.ToString();
encoder.FlipHorizontal = true;
encoder.FlipVertical = false;
encoder.QualityLevel = 30;
encoder.Rotation = Rotation.Rotate90;
encoder.Frames.Add(BitmapFrame.Create(image));
encoder.Save(stream);

Dim stream As New FileStream("new.jpg", FileMode.Create)
Dim encoder As New JpegBitmapEncoder()
Dim myTextBlock As New TextBlock()
myTextBlock.Text = "Codec Author is: " + encoder.CodecInfo.Author.ToString()
encoder.FlipHorizontal = True
encoder.FlipVertical = False
encoder.QualityLevel = 30
encoder.Rotation = Rotation.Rotate90
encoder.Frames.Add(BitmapFrame.Create(image))
encoder.Save(stream)

Hinweise

XAML-Textverwendung

Der horizontale Flip stellt eine verlustlose Transformation des Quellbilds dar und ersetzt alle vorherigen verlustlosen Transformationen.
