ID2D1Geometry::Simplify method

Creates a simplified version of the geometry that contains only lines and (optionally) cubic Bezier curves and writes the result to an ID2D1SimplifiedGeometrySink.

Syntax


virtual HRESULT Simplify(
  D2D1_GEOMETRY_SIMPLIFICATION_OPTION simplificationOption,
  [in, optional]  const D2D1_MATRIX_3X2_F *worldTransform,
  FLOAT flatteningTolerance,
  [in]            ID2D1SimplifiedGeometrySink *geometrySink
) const = 0;

Parameters

simplificationOption

Type: D2D1_GEOMETRY_SIMPLIFICATION_OPTION

A value that specifies whether the simplified geometry should contain curves.

worldTransform [in, optional]

Type: const D2D1_MATRIX_3X2_F*

The transform to apply to the simplified geometry, or NULL.

flatteningTolerance

Type: FLOAT

The maximum error allowed when constructing a polygonal approximation of the geometry. No point in the polygonal representation will diverge from the original geometry by more than the flattening tolerance. Smaller values produce more accurate results but cause slower execution.

geometrySink [in]

Type: ID2D1SimplifiedGeometrySink*

The ID2D1SimplifiedGeometrySink to which the simplified geometry is appended.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
