BmpBitmapEncoder Class
Assembly: PresentationCore (in presentationcore.dll)
XML Namespace: http://schemas.microsoft.com/winfx/2006/xaml/presentation
Bitmap (BMP) format does not support features that are supported by other bitmap formats, including global preview, global thumbnail, global metadata, frame level thumbnails, multiple frames, and frame level metadata.
Encoding does not work in partial trust. See the Windows Presentation Foundation Partial Trust Programming topic for information on partial trust.
The following example demonstrates how to use the BmpBitmapEncoder to encode a new bitmap image.
Dim width As Integer = 128 Dim height As Integer = width Dim stride As Integer = CType(width / 8, Integer) Dim pixels(height * stride) As Byte ' Try creating a new image with a custom palette. Dim colors As New List(Of System.Windows.Media.Color)() colors.Add(System.Windows.Media.Colors.Red) colors.Add(System.Windows.Media.Colors.Blue) colors.Add(System.Windows.Media.Colors.Green) Dim myPalette As New BitmapPalette(Colors) ' Creates a new empty image with the pre-defined palette Dim image As BitmapSource = System.Windows.Media.Imaging.BitmapSource.Create(width, height, 96, 96, PixelFormats.Indexed1, myPalette, pixels, stride) Dim stream As New FileStream("new.bmp", FileMode.Create) Dim encoder As New BmpBitmapEncoder() Dim myTextBlock As New TextBlock() myTextBlock.Text = "Codec Author is: " + encoder.CodecInfo.Author.ToString() encoder.Frames.Add(BitmapFrame.Create(image)) encoder.Save(stream)
