Print DirectX/Xaml Interop UI RRS feed

  • Question

  • Hi,

    My application uses SurfaceImageSource to show DirectX and Xaml UI elements. The application UI should be printed out as XPS/PDF. I've tried use PrintManager and PrintDocument. However, most Xaml elements can be printed except SurfaceImageSource which prints nothing. Another way is using PrintManager and ID2D1CommandList. But it is only for printing DirectX. Any good method to print both Xaml and DirectX?

  • Hi,

    how about using SwapChainBackgroundPanel?

    you may share your repro sample on a public website like skydrive, then we can have a check.

  • Hi Jenny,

    SwapChainBackgroundPanel always renders under other Xaml controls but our application has to show some DirectX UI on top. So it isn't suitable in our case. I did try to print SwapChainBackgroundPanel through PrintManager as well. However, because SwapChainBackgroundPanel must be the root element, I can't add it as a child of PrintDocument. It throws an exception.

    I will repro my sample on skydrive later.

  • Hi,

    Here is my Sample modified from MSDN official C++ print sample.

    Basically, what I did is:

    1. In ScenarioOutput2.xaml.cpp, create a SurfaceImageSource object, draw a green rectangle and attach it on an Image object.
    2. Press print button and see preview. The image object inside preview shows nothing.

  • I've tested a workaround and it works.

    Before printing, redraw DirectX UI elements to a bitmap (WICBitmap) and then assign this bitmap back to an Xaml image element. In the other word, I translate DirectX UI element to a Xaml image element by myself, instead of printing SurfaceImageSource directly.

    The sample: Direct2D and WIC Image Editor helps a lot. It saves time to learn how to draw D2D elements to a bitmap and use it in Xaml.
