  IInkStrokes* strokes,
  InkExtractFlags extractFlags,
  IInkDisp **extractedInk
);

Parameters

  • strokes
    [in, optional] Specifies the collection of strokes to extract. The default value of 0 specifies that all strokes are extracted.
  • extractFlags
    [in, optional] Specifies the InkExtractFlags enumeration type, which specifies whether the ink is cut or copied into the new IInkDisp object. The default value of IEF_Default cuts the strokes.
  • extractedInk
    [out, retval] Returns a new IInkDisp object that contains the extracted collection of cut or copied strokes.

Return Value

  • S_OK
    Success.
  • E_POINTER
    A parameter contained an invalid pointer.
  • E_INK_MISMATCHED_INK_OBJECT
    The IInkDisp object of the IInkStrokes collection must match the known IInkDisp object.
