How to simply render ID3D11Texture2D - directx-11

I am doing a D2D/D3D interoperability program. After getting ID3D11Texture2D from the outside, it is rendered in a designated area. I tried CreateDxgiSurfaceRenderTarget but no effect
code below, The code runs "normally", there are no errors and debugging information is displayed, But the interface shows a black screen. If you ignore the param texture, changing to only _back_render_target->FillRectange is effective
HRESULT CGraphRender::DrawTexture(ID3D11Texture2D* texture, const RECT& dst_rect)
{
float dpi = GetDpiFromD2DFactory(_d2d_factory);
CComPtr<ID3D11Texture2D> temp_texture2d;
CComPtr<ID2D1RenderTarget> temp_render_target;
CComPtr<ID2D1Bitmap> temp_bitmap;
D3D11_TEXTURE2D_DESC desc = { 0 };
texture->GetDesc(&desc);
CD3D11_TEXTURE2D_DESC capture_texture_desc(DXGI_FORMAT_B8G8R8A8_UNORM, desc.Width, desc.Height, 1, 1, D3D11_BIND_RENDER_TARGET);
HRESULT hr = _d3d_device->CreateTexture2D(&capture_texture_desc, nullptr, &temp_texture2d);
RETURN_ON_FAIL(hr);
CComPtr<IDXGISurface> dxgi_capture;
hr = temp_texture2d->QueryInterface(IID_PPV_ARGS(&dxgi_capture));
RETURN_ON_FAIL(hr);
D2D1_RENDER_TARGET_PROPERTIES rt_props = D2D1::RenderTargetProperties(D2D1_RENDER_TARGET_TYPE_DEFAULT, D2D1::PixelFormat(DXGI_FORMAT_B8G8R8A8_UNORM, D2D1_ALPHA_MODE_PREMULTIPLIED), dpi, dpi);
hr = _d2d_factory->CreateDxgiSurfaceRenderTarget(dxgi_capture, rt_props, &temp_render_target);
RETURN_ON_FAIL(hr);
D2D1_BITMAP_PROPERTIES bmp_prop = D2D1::BitmapProperties(D2D1::PixelFormat(DXGI_FORMAT_B8G8R8A8_UNORM, D2D1_ALPHA_MODE_PREMULTIPLIED), dpi, dpi);
hr = temp_render_target->CreateBitmap(D2D1::SizeU(desc.Width, desc.Height), bmp_prop, &temp_bitmap);
RETURN_ON_FAIL(hr);
CComPtr<ID3D11DeviceContext> immediate_context;
_d3d_device->GetImmediateContext(&immediate_context);
if (!immediate_context)
{
return E_UNEXPECTED;
}
immediate_context->CopyResource(temp_texture2d, texture);
D2D1_POINT_2U src_point = D2D1::Point2U();
D2D1_RECT_U src_rect = D2D1::RectU(0, 0, desc.Width, desc.Height);
hr = temp_bitmap->CopyFromRenderTarget(&src_point, temp_render_target, &src_rect);
RETURN_ON_FAIL(hr);
D2D1_RECT_F d2d1_rect = { (float)dst_rect.left, (float)dst_rect.top, (float)dst_rect.right, (float)dst_rect.bottom};
_back_render_target->DrawBitmap(temp_bitmap, d2d1_rect);
return S_OK;
}
Refer to DirectXTK, DirectXTK's SpritBatch code has a brief look. It is necessary to introduce a bunch of context settings. I don’t understand the relationship yet. I don’t know. Does the existing code have any influence, such as setting TargetView, ViewPort or even Shader.
Is there a relatively simple and effective method, as simple and violent as ID2D1RenderTarget's DrawBitmap?

DirectX screen capture on Windows 10/11

I'm trying to create a screen taking app that can get a raw bitmap of a desktop window from the GPU. I did it via GDI and it works properly, but using both DirectX and DXGI Duplication api, I have black screen or an error.

p.s: Do I understand correctly that when using GetDesktopWindow() am I capturing a desktop containing an image of the entire screen?
Some help in solving this problem is needed

Failure to create EGLSurface using the RenderResolutionScale property on Windows

I'm trying to create an EGLSurface in a Windows UWP app. The creation code is in a xaml.cpp file, as shown below.
When I try creating the surface using the optional property EGLRenderResolutionScaleProperty, it fails with an EGL_BAD_ALLOC error. Two alternate approaches work, but I need to try to use the resolution scale option for my app.
void MyClass::CreateRenderSurface()
{
if (mRenderSurface == EGL_NO_SURFACE)
{
// NOTE: in practice, I only have one of the three following implementations in the code;
// all are included together here for ease of comparison.
// 1. This works
mRenderSurface = CreateSurface(mSwapChainPanel, nullptr, nullptr);
// 2. and this works (here I hardwired the size to twice the
// the size of the window I happen to be using, because
// Windows display settings is set at 200%)
Size size;
size.Height = 1448; // hardwired value for testing, in this case window height is 724 pix
size.Width = 1908; // hardwired value for testing, in this case window width is 954 pix
mRenderSurface = CreateSurface(mSwapChainPanel, &size, nullptr);
// 3. but this fails (and this is the one I want to use)
float resolutionScale = 1.0;
mRenderSurface = CreateSurface(mSwapChainPanel, nullptr, &resolutionScale);
}
}
EGLSurface MyClass::CreateSurface(SwapChainPanel^ panel, const Size* renderSurfaceSize, const float* resolutionScale)
{
if (!panel)
{
throw Exception::CreateException(E_INVALIDARG, L"SwapChainPanel parameter is invalid");
}
if (renderSurfaceSize != nullptr && resolutionScale != nullptr)
{
throw Exception::CreateException(E_INVALIDARG, L"A size and a scale can't both be specified");
}
EGL _egl = this->HelperClass->GetEGL();
EGLSurface surface = EGL_NO_SURFACE;
const EGLint surfaceAttributes[] =
{
EGL_ANGLE_SURFACE_RENDER_TO_BACK_BUFFER, EGL_TRUE,
EGL_NONE
};
// Create a PropertySet and initialize with the EGLNativeWindowType.
PropertySet^ surfaceCreationProperties = ref new PropertySet();
surfaceCreationProperties->Insert(ref new String(EGLNativeWindowTypeProperty), panel);
// If a render surface size is specified, add it to the surface creation properties
if (renderSurfaceSize != nullptr)
{
surfaceCreationProperties->Insert(ref new String(EGLRenderSurfaceSizeProperty), PropertyValue::CreateSize(*renderSurfaceSize));
}
// If a resolution scale is specified, add it to the surface creation properties
if (resolutionScale != nullptr)
{
surfaceCreationProperties->Insert(ref new String(EGLRenderResolutionScaleProperty), PropertyValue::CreateSingle(*resolutionScale));
}
surface = eglCreateWindowSurface(_egl._display, _egl._config, reinterpret_cast<IInspectable*>(surfaceCreationProperties), surfaceAttributes);
EGLint err = eglGetError();
if (surface == EGL_NO_SURFACE)
{
throw Exception::CreateException(E_FAIL, L"Failed to create EGL surface");
}
return surface;
}
where
const wchar_t EGLNativeWindowTypeProperty[] = L"EGLNativeWindowTypeProperty";
const wchar_t EGLRenderSurfaceSizeProperty[] = L"EGLRenderSurfaceSizeProperty";
const wchar_t EGLRenderResolutionScaleProperty[] = L"EGLRenderResolutionScaleProperty";
I have tried changing the cast of the EGLNativeWindowType argument (as in How to create EGLSurface using C++/WinRT and ANGLE?) - that only creates other problems. As indicated, this code does work to create a surface in the basic case, just not when using the EGLRenderResolutionScaleProperty.
My guess is that something about the way I'm supplying that property is failing, because it fails on what should be reasonable values (e.g., 1.0).
Solved this by first checking that swapChainPanel size is not zero:
void MyClass::CreateRenderSurface()
{
if (mRenderSurface == EGL_NO_SURFACE)
{
if (0 == mSwapChainPanel->ActualHeight || 0 == mSwapChainPanel->ActualWidth)
{
mRenderSurface = CreateSurface(mSwapChainPanel, nullptr, &resolutionScale);
}
}
}
(The code checks elsewhere whether the render surface has been created, and will call this again if needed.)
Interestingly, the original code that used nullptr for both size and resolution arguments (case 1 in original snippet above) didn't need that check.

Use a texture array as Direct2D surface render target

I try to create a Direct3D 11 texture array holding multiple pages of text rendered using DirectWrite and Direct2D. Suppose layout holds the IDWriteTextLayouts for the individual pages, then I try to do the following:
{
D3D11_TEXTURE2D_DESC desc;
::ZeroMemory(&desc, sizeof(desc));
desc.ArraySize = static_cast<UINT>(layouts.size());
desc.BindFlags = D3D11_BIND_RENDER_TARGET;
desc.Format = DXGI_FORMAT_B8G8R8A8_UNORM;
desc.Height = height;
desc.MipLevels = 1;
desc.SampleDesc.Count = 1;
desc.Usage = D3D11_USAGE_DEFAULT;
desc.Width = width;
auto hr = this->_d3dDevice->CreateTexture2D(&desc, nullptr, &retval.Texture);
if (FAILED(hr)) {
throw std::system_error(hr, com_category());
}
}
for (auto &l : layouts) {
ATL::CComPtr<IDXGISurface> surface;
{
auto hr = retval.Texture->QueryInterface(&surface);
if (FAILED(hr)) {
// The code fails here with E_NOINTERFACE "No such interface supported."
throw std::system_error(hr, com_category());
}
}
// Go on creating the RT from 'surface'.
}
The problem is that the code fails at the designated line where I try to obtain the IDXGISurface interface from the ID3D11Texture2D if there is more than one page (desc.ArraySize > 1). I eventually found in the documentation (https://learn.microsoft.com/en-us/windows/win32/api/dxgi/nn-dxgi-idxgisurface) that this is by deisgn:
If the 2D texture [...] does not consist of an array of textures, QueryInterface succeeds and returns a pointer to the IDXGISurface interface pointer. Otherwise, QueryInterface fails and does not return the pointer to IDXGISurface.
Is there any other way to obtain the individual DXGI surfaces in the texture array to draw to them one after the other using Direct2D?
As I could not find any way to address the sub-surfaces, I now create a staging texture with one layer to render to and copy the result into the texture array using ID3D11DeviceContext::CopySubresourceRegion.
How about Texture => IDXGIResource1 => CreateSubresourceSurface ?

Occur _com_error when using CreateHwndRenderTarget()

I use Direct2D to render the animation on VS2010. But when I create over 100 animation objects (the limitation amount is variable),
the output window shows the error message:
"First-chance exception at 0x7607C42D in StarrySky.exe: Microsoft C++
exception: _com_error at memory location 0x001C9580."
However, the error does not interupt the program, and the animation object's seems correct.
I trace the code and find out the error message print after calling
hr = m_pD2DFactory->CreateHwndRenderTarget(renderTargetProperties,
D2D1::HwndRenderTargetProperties(this->m_hWnd, size), &m_pRT);
But the return hr is S_OK. Does anyone know the reason or the solution?
In Direct2D, make sure you are instantiating the device independent resources (In Constructor or something - Init_D2D() in this code example) before device dependent resources. For instance,
// In your header files
ID2D1Factory* pD2DFactory; // device independent
ID2D1HwndRenderTarget* pRenderTarget;
// In the source files
void Init_D2D() // probably in constructor
{
HRESULT hr = D2D1CreateFactory(
D2D1_FACTORY_TYPE_SINGLE_THREADED, &pD2DFactory);
}
void Create_D2D_Device_Dep() //before drawing
{
if(pRenderTarget == NULL) //if it exists, do not create again
{
HRESULT hr = pD2DFactory->CreateHwndRenderTarget(
D2D1::RenderTargetProperties(),
D2D1::HwndRenderTargetProperties(m_hWnd,
D2D1::SizeU((UINT32)m_pRect.right, (UINT32)m_pRectWindow.bottom)),
&pRenderTarget);
}
}
OnPaint() method should be something like this,
void CPlotterView::OnPaint_D2D()
{
HRESULT hr;
hr = Create_D2D_Device_Dep();
if (SUCCEEDED(hr))
{
//pRenderTarget->SetAntialiasMode(D2D1_ANTIALIAS_MODE_ALIASED);
pRenderTarget->BeginDraw();
D2D1_SIZE_F renderTargetSize = pRenderTarget->GetSize();
pRenderTarget->SetTransform(D2D1::Matrix3x2F::Identity());
pRenderTarget->Clear(D2D1::ColorF(D2D1::ColorF::LightYellow));
// Drawlines or ellipses using pRenderTarget->DrawEllipse() or something
hr = pRenderTarget->EndDraw();
}
if (hr == D2DERR_RECREATE_TARGET)
{
Free_D2D_Device_Dep();
}
else
{
::ValidateRect(m_hWnd, NULL);
}
}
At the end, do not forget to close/release the resources, in the same order you opened.

ExtTextOutW() with ETO_IGNORELANGUAGE failed to capture the record

I am working on a sample in this I am creating a EMF file with some text in it.
To add a text I am using the API ExtTextOutW() with ETO_IGNORELANGUAGE option.
Return value of this API is TRUE. But when I open the EMF file the text is not present.
Then I saw the records. There is no entey for the ExtTextOutW.
Bellw is the code.
HDC hDC = GetDC(hWnd);
RECT Rect = {0, 0, 21590, 27940};
//Create the EMF file DC
HDC hEMFDC = ::CreateEnhMetaFile(hDC, L"c:\\del\\1.emf", &Rect, L"Test");
if (NULL != hEMFDC)
{
RECT Rect = {0, 0, 300, 155};
HBRUSH hb = CreateSolidBrush(0X00FFFF00);
FillRect(hEMFDC, &Rect, hb);
DeleteObject(hb);
int dx[12] = {25,25,25,25,25,25, 25,25,25,25,25,25};
WCHAR wcsBuffer[] = L"Text Message";
ExtTextOutW(hEMFDC, 10, 10, ETO_IGNORELANGUAGE, NULL, wcsBuffer, wcslen(wcsBuffer), dx);
HENHMETAFILE hmf = CloseEnhMetaFile(hEMFDC);
DeleteEnhMetaFile(hmf);
hEMFDC = NULL;
}
ReleaseDC(hWnd, hDC);
Please let me know any thing I am doing wrong in the above code.
Did you read the documentation for ExtTextOut[W] (MSDN), especially the part for the flags like ETO_IGNORELANGUAGE:
Reserved for system use. If an application sets this flag, it loses
international scripting support and in some cases it may display no
text at all.
Just try it without this flag.
