PngBitmapEncoder.Interlace 屬性

定義

取得或設定值,指出可攜式網狀圖形 (PNG) 點陣圖是否應該交錯。

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

屬性值

PngInterlaceOption

其中一個 Interlace 值。 預設為 Default

範例

下列範例示範如何使用 Interlace 屬性。

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)

備註

交錯是指在兩個欄位中顯示 PNG 框架的程式。 一個欄位包含框架的偶數線,另一個欄位則包含框架的奇數線。 檢視 PNG 時,會先顯示一個欄位中的行,然後顯示第二個欄位中的行。
