With the LEADTOOLS WPF Module and Raster Imaging SDK, you can take the following steps to create and run a program in Microsoft Expression Blend that loads and saves an image using the LEADTOOLS ImageViewer.
##### Objects Required
Type | Name | Purpose |
Window | Window | Main window |
Grid | LayoutRoot | Grid acts as the container for the objects to be added. |
Canvas | _canvas | Sets objects as fixed points in the LayoutRoot. |
Label | _label | Displays a description of the window. |
ImageViewer | _viewer | LEADTOOLS object to view raster images. |
Button | _load | Triggers loading an image event. |
Button | _save | Triggers saving a loaded image event. |
TextBox | _savePath | Absolute path where image is saved to. |
TextBox | _loadPath | Absolute path where the image is loaded from. |

Create the trigger event for loading the image.
In the text field type up a descriptive name of the method to handle the click event: "_load_Click". Double-click the field to save and exit.
Visual Studio will start and will add a method to the C# code used behind the interface.
private void _load_Click(object sender, RoutedEventArgs e)
{ using (Leadtools.Codecs.RasterCodecs codecs = new Leadtools.Codecs.RasterCodecs())
{ _viewer.Image = codecs.Load(_loadPath.Text, bitsPerPixel, Leadtools.Codecs.CodecsLoadByteOrder.Bgr, pageNumber, pageNumber); }
}
Create the trigger event for saving the image.
private void _save_Click(object sender, RoutedEventArgs e)
{ using (Leadtools.Codecs.RasterCodecs codecs = new Leadtools.Codecs.RasterCodecs())
{ codecs.Save(_viewer.Image, _savePath.Text, Leadtools.RasterImageFormat.Cmp, bitsPerPixel); }
}
private int bitsPerPixel = 0;
private int qualityFactor = 2;
private int pageNumber = 1;
