ComponentOne Bitmap for WinForms
C1.Win.C1DX.4.8 Assembly / C1.Util.DX.Direct2D Namespace / D2D1 Class / ComputeFlatteningTolerance Method
The matrix that will be applied subsequently to the geometry being flattened.
The horizontal DPI of the render target that the geometry will be rendered onto (a choice of 96 implies no DPI correction).
The vertical DPI of the render target that the geometry will be rendered onto (a choice of 96 implies no DPI correction).
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.

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

    Parameters

    matrix
    The matrix that will be applied subsequently to the geometry being flattened.
    dpiX
    The horizontal DPI of the render target that the geometry will be rendered onto (a choice of 96 implies no DPI correction).
    dpiY
    The vertical DPI of the render target that the geometry will be rendered onto (a choice of 96 implies no DPI correction).
    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.

    Return Value

    The flattening tolerance.
