C++ (Cpp) VerifyBufferSize Examples

Example #1

void
LayerManagerD3D10::SetupPipeline()
{
  VerifyBufferSize();
  UpdateRenderTarget();

  nsIntRect rect;
  mWidget->GetClientBounds(rect);

  HRESULT hr;

  hr = mEffect->GetVariableByName("vTextureCoords")->AsVector()->
    SetFloatVector(ShaderConstantRectD3D10(0, 0, 1.0f, 1.0f));

  if (FAILED(hr)) {
    NS_WARNING("Failed to set Texture Coordinates.");
    return;
  }

  ID3D10RenderTargetView *view = mRTView;
  mDevice->OMSetRenderTargets(1, &view, NULL);
  mDevice->IASetInputLayout(mInputLayout);

  UINT stride = sizeof(Vertex);
  UINT offset = 0;
  ID3D10Buffer *buffer = mVertexBuffer;
  mDevice->IASetVertexBuffers(0, 1, &buffer, &stride, &offset);
  mDevice->IASetPrimitiveTopology(D3D10_PRIMITIVE_TOPOLOGY_TRIANGLESTRIP);

  SetViewport(nsIntSize(rect.width, rect.height));
}

Example #2

File: CompositorD3D11.cpp Project: msliu/gecko-dev

void
CompositorD3D11::UpdateRenderTarget()
{
  EnsureSize();
  VerifyBufferSize();

  if (mDefaultRT) {
    return;
  }

  HRESULT hr;

  nsRefPtr<ID3D11Texture2D> backBuf;

  hr = mSwapChain->GetBuffer(0, __uuidof(ID3D11Texture2D), (void**)backBuf.StartAssignment());
  if (Failed(hr)) {
    return;
  }

  mDefaultRT = new CompositingRenderTargetD3D11(backBuf, IntPoint(0, 0));
  mDefaultRT->SetSize(mSize.ToIntSize());
}
