Adding Bitmap Effects Using Expression Blend

With LEADTOOLS for WPF, you can take the following steps to add special effects to images, buttons, or other items. You can add LEADTOOLS effects to Windows objects, Windows effects to LEADTOOLS objects, or any combination of effects to almost any object.

  1. In Microsoft Expression Blend, open a project. If you wish, open the project you created in the Link an Image List to an Image Viewer tutorials.
  2. From the Interaction tab, under Objects and Timeline, select an object. In this example, select an ImageListItem.
  3. From the Properties tab, under Appearance, select the down arrow
    to expand the Advanced Properties options.
  4. Choose **BitmapEffect-->New.  **A Select Object window will appear.

    There are two groups of effects: Leadtools.Windows.Media.Effects, and PresentationCore.

    • Under Leadtools.Windows.Media.Effects, you will see the five namespaces that make up the assembly, including Leadtools.Windows.Media.Effects, Leadtools.Windows.Media.Effects.Color, Leadtools.Windows.Media.Effects.Core, Leadtools.Windows.Media.Effects.Effects, and Leadtools.Windows.Media.Effects.SpecialEffects.
    • Under PresentationCore, you will see effects available from the Windows system (System.Windows.Media.Effects). These include Bevel, Blur, DropShadow, Emboss, and OuterGlow. The Microsoft System effects can be used alone, or, they can be combined with the much larger collection of effects available under Leadtools.Windows.Media.Effects:

  5. Under Presentation Core, look below System.Windows.Media.Effects, and select BevelBitmapEffect.

  6. Repeat steps 2 through 5 until you have applied this effect to all ImageListItems.
  7. Press F5 to build your application. Each image list item will now appear with beveled edges:

  3. Under the Leadtools.Windows.Media.Effects group, expand Leadtools.Windows.Media.Effects.SpecialEffects, select BricksTextureCommandBitmapEffect, and then click OK.
  4. On the Properties tab, expand Appearance. Under BitmapEffect, you can adjust variables like brick height, roughness, width, and color.
  5. Press F5 to build your application. Depending on the variables you selected for your button and for the bricks effect, the button will look something like this:
