BitmapImage.DecodePixelHeight Property
Gets or sets the height, in pixels, that the image is decoded to.
Namespace: System.Windows.Media.Imaging
Assembly: PresentationCore (in PresentationCore.dll)
XMLNS for XAML: http://schemas.microsoft.com/winfx/2006/xaml/presentation, http://schemas.microsoft.com/netfx/2007/xaml/presentation
<object DecodePixelHeight="int" .../>
Property Value
Type: System.Int32The height, in pixels, that the image is decoded to. The default value is 0.
If DecodePixelWidth is also set, the aspect ratio of the bitmap is ignored. If DecodePixelWidth 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 DecodePixelHeight property by using code.
// Define a BitmapImage. Image myImage = new Image(); BitmapImage bi = 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);
