C1.Util.DX.Direct2D.D2D1.ComputeFlatteningTolerance

ComputeFlatteningTolerance Method

ComputeFlatteningTolerance(ref Matrix3x2, float, float, float)

Computes the appropriate flattening tolerance to pass to APIs that take a flattening tolerance (for instance, DeviceContext.CreateFilledGeometryRealization).

Declaration

public static float ComputeFlatteningTolerance(ref Matrix3x2 matrix, float dpiX = 96, float dpiY = 96, float maxZoomFactor = 1)

Public Shared Function ComputeFlatteningTolerance(ByRef matrix As Matrix3x2, Optional dpiX As Single = 96, Optional dpiY As Single = 96, Optional maxZoomFactor As Single = 1) As Single

Parameters

Type	Name	Description
Matrix3x2	matrix	The matrix that will be applied subsequently to the geometry being flattened.
float	dpiX	The horizontal DPI of the render target that the geometry will be rendered onto (a choice of 96 implies no DPI correction).
float	dpiY	The vertical DPI of the render target that the geometry will be rendered onto (a choice of 96 implies no DPI correction).
float	maxZoomFactor	The maximum amount of additional scaling (on top of any scaling implied by the matrix or the DPI) that will be applied to the geometry.

Returns

Type	Description
float	The flattening tolerance.
