ID2D1Geometry::Widen methods

Widens the geometry by the specified stroke and writes the result to an ID2D1SimplifiedGeometrySink.

Overload list

MethodDescription
Widen(FLOAT,ID2D1StrokeStyle*,D2D1_MATRIX_3X2_F*,ID2D1SimplifiedGeometrySink*)

Widens the geometry by the specified stroke and writes the result to an ID2D1SimplifiedGeometrySink after it has been transformed by the specified matrix and flattened using the default tolerance.

Widen(FLOAT,ID2D1StrokeStyle*,D2D1_MATRIX_3X2_F&,ID2D1SimplifiedGeometrySink*)

Widens the geometry by the specified stroke and writes the result to an ID2D1SimplifiedGeometrySink after it has been transformed by the specified matrix and flattened using the default tolerance.

Widen(FLOAT,ID2D1StrokeStyle*,D2D1_MATRIX_3X2_F*,FLOAT,ID2D1SimplifiedGeometrySink*)

Widens the geometry by the specified stroke and writes the result to an ID2D1SimplifiedGeometrySink after it has been transformed by the specified matrix and flattened using the specified tolerance.

Widen(FLOAT,ID2D1StrokeStyle*,D2D1_MATRIX_3X2_F&,FLOAT,ID2D1SimplifiedGeometrySink*)

Widens the geometry by the specified stroke and writes the result to an ID2D1SimplifiedGeometrySink after it has been transformed by the specified matrix and flattened using the specified tolerance.

Examples

The following code example shows how to use Widen to widen the geometry by the specified stroke and then write the result to an ID2D1SimplifiedGeometrySink object.

C++
Copy 

 ID2D1GeometrySink *pGeometrySink = NULL;
 hr = pPathGeometry->Open(&pGeometrySink);
 if (SUCCEEDED(hr))
 {
     hr = pGeometry->Widen(
             strokeWidth,
             pIStrokeStyle,
             pWorldTransform,
             pGeometrySink
             );

     if (SUCCEEDED(hr))
     {
         hr = pGeometrySink->Close();
         if (SUCCEEDED(hr))
         {
             ID2D1Mesh *pMesh = NULL;
             hr = m_pRT->CreateMesh(&pMesh);
             if (SUCCEEDED(hr))
             {
                 ID2D1TessellationSink *pSink = NULL;
                 hr = pMesh->Open(&pSink);
                 if (SUCCEEDED(hr))
                 {
                     hr = pPathGeometry->Tessellate(
                             NULL, // world transform (already handled in Widen)
                             pSink
                             );
                     if (SUCCEEDED(hr))
                     {
                         hr = pSink->Close();
                         if (SUCCEEDED(hr))
                         {
                             SafeReplace(&m_pStrokeMesh, pMesh);
                         }
                     }
                     pSink->Release();
                 }
                 pMesh->Release();
             }
         }
     }
     pGeometrySink->Release();
 }
 pPathGeometry->Release();
