BitmapImage.DecodePixelWidth Property
Gets or sets the width, in pixels, that the image is decoded to. This is a dependency property.
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 DecodePixelWidth="int" .../>
Property Value
Type: System.Int32The width, in pixels, that the image is decoded to. The default value is 0.
If DecodePixelHeight is not set, the aspect ratio of the bitmap remains unaltered. If DecodePixelHeight is set, the aspect ratio is ignored.
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. 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);
