JpegBitmapEncoder.FlipVertical プロパティ

定義

名前空間:

System.Windows.Media.Imaging

アセンブリ:

PresentationCore.dll

エンコード中に Joint Photographics Experts Group (JPEG) イメージを垂直方向に反転させるかどうかを示す値を取得または設定します。

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

public bool FlipVertical { get; set; }

member this.FlipVertical : bool with get, set

Public Property FlipVertical As Boolean

プロパティ値

Boolean

エンコード時にイメージを上下反転させる場合は true。それ以外の場合は false。

例

次の例では、 プロパティの値を設定する方法を FlipVertical 示します。

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)

注釈

垂直方向の反転は、ソース イメージの無損失変換を表し、以前の無損失変換を置き換えます。
