IInkStrokeDisp::Shear

Shears the ink in the IInkStrokeDisp stroke object by the specified horizontal and vertical factors.

Syntax

HRESULT Shear (
  [in] float shearX,
  [in] float shearY
);

Parameters

  • shearX
    [in] The horizontal factor of the shear.
  • shearY
    [in] The vertical factor of the shear.

Return Value

  • S_OK
    Success.
  • E_INK_EXCEPTION
    An exception occurred inside the method.

Remarks

The transformation applied in this method is a pure shear only if one of the parameters is 0. Applied to a rectangle at the origin, when the shearY factor is 0, the transformation moves the bottom edge horizontally by shearX times the height of the rectangle. When the shearX factor is 0, it moves the right edge vertically by shearY times the width of the rectangle.

Note

When both parameters are nonzero, the results may not be intuitive.

This method throws an exception if the shear is non–invertible. The shear is non–invertible if the product of the shearX and shearY parameters equals 1.
