ID2D1RenderTarget::PopLayer method (d2d1.h)
Stops redirecting drawing operations to the layer that is specified by the last PushLayer call.
Syntax
void PopLayer();
Return value
None
Remarks
A PopLayer must match a previous PushLayer call.
This method doesn't return an error code if it fails. To determine whether a drawing operation (such as PopLayer) failed, check the result returned by the ID2D1RenderTarget::EndDraw or ID2D1RenderTarget::Flush methods.
Examples
The following example uses a layer to clip a bitmap to a geometric mask. For the complete example, see How to Clip to a Geometric Mask.
HRESULT DemoApp::RenderWithLayer(ID2D1RenderTarget *pRT)
{
HRESULT hr = S_OK;
// Create a layer.
ID2D1Layer *pLayer = NULL;
hr = pRT->CreateLayer(NULL, &pLayer);
if (SUCCEEDED(hr))
{
pRT->SetTransform(D2D1::Matrix3x2F::Translation(350, 50));
// Push the layer with the geometric mask.
pRT->PushLayer(
D2D1::LayerParameters(D2D1::InfiniteRect(), m_pPathGeometry),
pLayer
);
pRT->DrawBitmap(m_pOrigBitmap, D2D1::RectF(0, 0, 200, 133));
pRT->FillRectangle(D2D1::RectF(0.f, 0.f, 25.f, 25.f), m_pSolidColorBrush);
pRT->FillRectangle(D2D1::RectF(25.f, 25.f, 50.f, 50.f), m_pSolidColorBrush);
pRT->FillRectangle(D2D1::RectF(50.f, 50.f, 75.f, 75.f), m_pSolidColorBrush);
pRT->FillRectangle(D2D1::RectF(75.f, 75.f, 100.f, 100.f), m_pSolidColorBrush);
pRT->FillRectangle(D2D1::RectF(100.f, 100.f, 125.f, 125.f), m_pSolidColorBrush);
pRT->FillRectangle(D2D1::RectF(125.f, 125.f, 150.f, 150.f), m_pSolidColorBrush);
pRT->PopLayer();
}
SafeRelease(&pLayer);
return hr;
}
