ID2D1Geometry::Outline(constD2D1_MATRIX_3X2_F&,FLOAT,ID2D1SimplifiedGeometrySink*) method (d2d1.h)

  • Article

Computes the outline of the geometry and writes the result to an ID2D1SimplifiedGeometrySink.

Syntax

HRESULT Outline(
  [ref] const D2D1_MATRIX_3X2_F &   worldTransform,
        FLOAT                       flatteningTolerance,
  [in]  ID2D1SimplifiedGeometrySink *geometrySink
);

Parameters

[ref] worldTransform

Type: const D2D1_MATRIX_3X2_F

The transform to apply to the geometry outline.

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.

[in] geometrySink

Type: ID2D1SimplifiedGeometrySink*

The ID2D1SimplifiedGeometrySink to which the geometry transformed outline is appended.

Return value

Type: HRESULT

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