'Declaration
 
Public Overloads Function SaveAsDOCX( _
   ByVal OCRResultIDs As ICollection(Of String), _
   ByVal Stream As Stream, _
   ByVal KeepLineBreaks As Boolean _
) As GdPictureStatus

public GdPictureStatus SaveAsDOCX( 
   ICollection<string> OCRResultIDs,
   Stream Stream,
   bool KeepLineBreaks
)

public function SaveAsDOCX( 
    OCRResultIDs: ICollection;
    Stream: Stream;
    KeepLineBreaks: Boolean
): GdPictureStatus;

public function SaveAsDOCX( 
   OCRResultIDs : ICollection,
   Stream : Stream,
   KeepLineBreaks : boolean
) : GdPictureStatus;

public: GdPictureStatus SaveAsDOCX( 
   ICollection<string*>* OCRResultIDs,
   Stream* Stream,
   bool KeepLineBreaks
)

public:
GdPictureStatus SaveAsDOCX( 
   ICollection<String^>^ OCRResultIDs,
   Stream^ Stream,
   bool KeepLineBreaks
)

Parameters

OCRResultIDs: A collection of the unique OCR result identifiers. It specifies the OCR results you want to save.
Stream: A Stream object where the results will be saved to. This Stream object must be initialized before it can be sent into this method and it should remain open for subsequent use.
KeepLineBreaks: The flag indicating whether to keep line breaks or not when saving the results.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK.

We strongly recommend always checking this status first.

Remarks

The output stream should be open for writing and should be closed/disposed by the user as well.
