This example shows how to crop an image using CroppedBitmap.
The following Extensible Application Markup Language (XAML) defines resources used within the samples below.
The following example creates an image using a CroppedBitmap as its source.
// Create an Image element. Image croppedImage = new Image(); croppedImage.Width = 200; croppedImage.Margin = new Thickness(5); // Create a CroppedBitmap based off of a xaml defined resource. CroppedBitmap cb = new CroppedBitmap( (BitmapSource)this.Resources["masterImage"], new Int32Rect(30, 20, 105, 50)); //select region rect croppedImage.Source = cb; //set image source to cropped
The CroppedBitmap can also be used as the source of another CroppedBitmap, chaining the cropping. Note that the SourceRect uses values that are relative to the source cropped bitmap and not the initial image.
// Create an Image element. Image chainImage = new Image(); chainImage.Width = 200; chainImage.Margin = new Thickness(5); // Create the cropped image based on previous CroppedBitmap. CroppedBitmap chained = new CroppedBitmap(cb, new Int32Rect(30, 0, (int)cb.Width-30, (int)cb.Height)); // Set the image's source. chainImage.Source = chained;
