A wrapper for ID2D1Geometry.

class CD2DGeometry : public CD2DResource;

Members

Public Constructors

Name	Description
CD2DGeometry::CD2DGeometry	Constructs a CD2DGeometry object.
CD2DGeometry::~CD2DGeometry	The destructor. Called when a D2D geometry object is being destroyed.

Public Methods

Name	Description
CD2DGeometry::Attach	Attaches existing resource interface to the object
CD2DGeometry::CombineWithGeometry	Combines this geometry with the specified geometry and stores the result in an ID2D1SimplifiedGeometrySink.
CD2DGeometry::CompareWithGeometry	Describes the intersection between this geometry and the specified geometry. The comparison is performed using the specified flattening tolerance.
CD2DGeometry::ComputeArea	Computes the area of the geometry after it has been transformed by the specified matrix and flattened using the specified tolerance.
CD2DGeometry::ComputeLength	Calculates the length of the geometry as though each segment were unrolled into a line.
CD2DGeometry::ComputePointAtLength	Calculates the point and tangent vector at the specified distance along the geometry after it has been transformed by the specified matrix and flattened using the specified tolerance.
CD2DGeometry::Destroy	Destroys a CD2DGeometry object. (Overrides CD2DResource::Destroy.)
CD2DGeometry::Detach	Detaches resource interface from the object
CD2DGeometry::FillContainsPoint	Indicates whether the area filled by the geometry would contain the specified point given the specified flattening tolerance.
CD2DGeometry::Get	Returns ID2D1Geometry interface
CD2DGeometry::GetBounds
CD2DGeometry::GetWidenedBounds	Gets the bounds of the geometry after it has been widened by the specified stroke width and style and transformed by the specified matrix.
CD2DGeometry::IsValid	Checks resource validity (Overrides CD2DResource::IsValid.)
CD2DGeometry::Outline	Computes the outline of the geometry and writes the result to an ID2D1SimplifiedGeometrySink.
CD2DGeometry::Simplify	Creates a simplified version of the geometry that contains only lines and (optionally) cubic Bezier curves and writes the result to an ID2D1SimplifiedGeometrySink.
CD2DGeometry::StrokeContainsPoint	Determines whether the geometry's stroke contains the specified point given the specified stroke thickness, style, and transform.
CD2DGeometry::Tessellate	Creates a set of clockwise-wound triangles that cover the geometry after it has been transformed using the specified matrix and flattened using the specified tolerance.
CD2DGeometry::Widen	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.

Public Operators

Name	Description
CD2DGeometry::operator ID2D1Geometry*	Returns ID2D1Geometry interface

Protected Data Members
