Public Property DecodePixelWidth As Integer

Property Value

Type: System.Int32

The width, in pixels, that the image is decoded to. The default value is 0.

IfDecodePixelHeight is also set, the aspect ratio of the bitmap is ignored. If DecodePixelHeight is not set, the aspect ratio remains the same.

The JPEG and Portable Network Graphics (PNG) codecs natively decode the image to the specified size; other codecs decode the image at its original size and scale the image to the desired size.

The following code example demonstrates how to set the DecodePixelWidth property by using code.

' Define a BitmapImage.
Dim myImage As New Image()
Dim bi As New BitmapImage()

' Begin initialization.
bi.BeginInit()

' Set properties.
bi.CacheOption = BitmapCacheOption.OnDemand
bi.CreateOptions = BitmapCreateOptions.DelayCreation
bi.DecodePixelHeight = 125
bi.DecodePixelWidth = 125
bi.Rotation = Rotation.Rotate90
MessageBox.Show(bi.IsDownloading.ToString())
bi.UriSource = New Uri("smiley.png", UriKind.Relative)

' End initialization.
bi.EndInit()
myImage.Source = bi
myImage.Stretch = Stretch.None
myImage.Margin = New Thickness(5)
