Specifies whether a Portable Network Graphics (PNG) format image is interlaced during encoding.
Assembly: PresentationCore (in PresentationCore.dll)
Interlacing refers to the process of displaying a PNG frame in two fields. One field contains the even lines of the frame, while 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.
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);
