ID2D1RenderTarget::FillOpacityMask methods
Applies the opacity mask described by the specified bitmap to a brush and uses that brush to paint a region of the render target.
Overload list
| Method | Description |
|---|---|
| FillOpacityMask(ID2D1Bitmap*,ID2D1Brush*,D2D1_OPACITY_MASK_CONTENT,D2D_RECT_F&,D2D_RECT_F&) | Applies the opacity mask described by the specified bitmap to a brush and uses that brush to paint a region of the render target. |
| FillOpacityMask(ID2D1Bitmap*,ID2D1Brush*,D2D1_OPACITY_MASK_CONTENT,D2D_RECT_F*,D2D_RECT_F*) | Applies the opacity mask described by the specified bitmap to a brush and uses that brush to paint a region of the render target. |
Remarks
For this method to work properly, the render target must be using the D2D1_ANTIALIAS_MODE_ALIASED antialiasing mode. You can set the antialiasing mode by calling the ID2D1RenderTarget::SetAntialiasMode method.
This method doesn't return an error code if it fails. To determine whether a drawing operation (such as FillOpacityMask) failed, check the result returned by the ID2D1RenderTarget::EndDraw or ID2D1RenderTarget::Flush methods.
