Hi,
 
I am using SharpDX 2.5 on Windows 7. I try to use PrintControl but it crashes on creation. I just don't know what to use as a TargetDocument??
 
Anyone has successfully used this API?
 
Here is where am at right now:
 
d2DFactory1 = new Factory1();
wicFactory2 = new ImagingFactory2();
            
// SwapChain description
var desc = new SwapChainDescription
    {
        BufferCount = 1,
        ModeDescription =
            new ModeDescription(ClientSize.Width, //Kernel.ViewManager.CurrentView.RenderingContext.Width,
                                ClientSize.Height, //Kernel.ViewManager.CurrentView.RenderingContext.Height,
                                new Rational(60, 1), Format.B8G8R8A8_UNorm),
        IsWindowed = true,
        OutputHandle = Handle,
        SampleDescription = new SampleDescription(1, 0),
        SwapEffect = SwapEffect.Discard,
        Usage = Usage.RenderTargetOutput
    };

// Create a D3D device and a swap chain
SharpDX.Direct3D11.Device.CreateWithSwapChain(
    DriverType.Hardware,
    DeviceCreationFlags.BgraSupport,
    new[] { FeatureLevel.Level_10_0 },
    desc,
    out d3DDevice, out dxgiSwapChain);

// Get a DXGI device interface from the D3D device.
using (var dxgiDevice = d3DDevice.QueryInterface<SharpDX.DXGI.Device>())
{
    d2DDevice = new SharpDX.Direct2D1.Device(d2DFactory1, dxgiDevice);
}

// Create a device context from the D2D device.
d2DContext = new DeviceContext(d2DDevice, DeviceContextOptions.None);

using (Surface dxgiSurface = dxgiSwapChain.GetBackBuffer<Surface>(0))
{
    var dpi = d2DFactory1.DesktopDpi;
    bitmap = new Bitmap1(d2DContext, dxgiSurface,
                            new BitmapProperties1(new PixelFormat(Format.Unknown, AlphaMode.Premultiplied),
                                                dpi.Width, dpi.Height,
                                                BitmapOptions.Target | BitmapOptions.CannotDraw));
}

solidColorBrush = new SolidColorBrush(d2DContext, Color.Red);

// Initialize print job (WILL CRASH HERE)
printControl = new PrintControl(d2DDevice, wicFactory2, bitmap,
                                new PrintControlProperties
                                    {
                                        RasterDPI = 150.0f,
                                        // Use the default rasterization DPI for all unsupported Direct2D commands.
                                        FontSubset = PrintFontSubsetMode.Default,
                                        // Using the default font subset strategy.
                                        ColorSpace = ColorSpace.SRgb
                                        // Color space for vector graphics in Direct2D print control.
                                    });

 
Thanks

Did it crash with an error message? 

 

I've never used a PrintControl, but it sounds like something that would depend on DX 11.1, so you would have to have the right assemblies and also the platform update that allows Windows 7 to use DX 11.1.

Thanks for the answer.

 

It does crash with a SharpDXException at SharpDX.Direct2D1.Device.CreatePrintControl.

 

I am running Win7 sp1 with the platform update, Windows SDK for Windows 7, vs2012 update 4, and my graphics card is a Quadro 1000M with a driver that does handle dx 11.1.  

 

Still dxdiag keeps telling me that my runtime is dx 11.0. I'm about to go back to GDI+ so I can do my project before Christmas...

My previous nVidia driver was telling me "taking charge of DirectX 11.1".

 

After installing latest driver from nVidia, it is no longer misleading... it simply tells DirectX 11.

 

Furthermore, if I only request feature level 11.1 in my code snippet, the app would crash at device creation tellin me it is not supported.

 

Thanks all, problem is the video card.

I think many nVidia cards do not support *all* features of DX11.1, but they will support most. I had to go through some hoops to get Direct2D DirectX11.1 interop for text drawing, but it does work on my vid cards which are not specifically 11.1 compatible. I can still use D2D to DX11 interop with featureLevel 11_0. I'm not sure what PrintControl requires.
