public:
property System::Windows::Media::Imaging::PngInterlaceOption Interlace { System::Windows::Media::Imaging::PngInterlaceOption get(); void set(System::Windows::Media::Imaging::PngInterlaceOption value); };
public System.Windows.Media.Imaging.PngInterlaceOption Interlace { get; set; }
member this.Interlace : System.Windows.Media.Imaging.PngInterlaceOption with get, set
Public Property Interlace As PngInterlaceOption
Property Value
One of the Interlace values. The default is Default.
Examples
The following example demonstrates how to use the Interlace property.
FileStream^ stream = gcnew FileStream("new.png", FileMode::Create);
PngBitmapEncoder^ encoder = gcnew PngBitmapEncoder();
TextBlock^ myTextBlock = gcnew TextBlock();
myTextBlock->Text = "Codec Author is: " + encoder->CodecInfo->Author->ToString();
encoder->Interlace = PngInterlaceOption::On;
encoder->Frames->Add(BitmapFrame::Create(image));
encoder->Save(stream);
FileStream stream = new FileStream("new.png", FileMode.Create);
PngBitmapEncoder encoder = new PngBitmapEncoder();
TextBlock myTextBlock = new TextBlock();
myTextBlock.Text = "Codec Author is: " + encoder.CodecInfo.Author.ToString();
encoder.Interlace = PngInterlaceOption.On;
encoder.Frames.Add(BitmapFrame.Create(image));
encoder.Save(stream);
Dim stream As New FileStream("new.png", FileMode.Create)
Dim encoder As New PngBitmapEncoder()
Dim myTextBlock As New TextBlock()
myTextBlock.Text = "Codec Author is: " + encoder.CodecInfo.Author.ToString()
encoder.Interlace = PngInterlaceOption.On
encoder.Frames.Add(BitmapFrame.Create(image))
encoder.Save(stream)
Remarks
Interlacing refers to the process of displaying a PNG frame in two fields. One field contains the even lines of the frame, and the other field contains the odd lines of the frame. When the PNG is viewed, the lines in one field are displayed first, and then the lines in the second field are displayed.
