The 0-based index of the required annotation within the selected page of the handled document. It must be a value from 0 to GetAnnotationCount-1.
Set this parameter to true if you want to flip the specified annotation horizontally; otherwise set it to false.
Set this parameter to true if you want to flip the specified annotation vertically; otherwise set it to false.

SetAnnotationFlipState Method (AnnotationManager)

In This Topic
Sets both the horizontal and the vertical flip states of a required GdPicture/XMP annotation object specified by its index related to the selected page of the document currently handled by this AnnotationManager object.

Be aware that this method only handles GdPicture/XMP annotations. Likewise, annotations are always treated relative to the selected page.

Syntax
'Declaration

 


Public Function SetAnnotationFlipState( _

   ByVal AnnotationIdx As Integer, _

   ByVal FlipX As Boolean, _

   ByVal FlipY As Boolean _

) As GdPictureStatus
public GdPictureStatus SetAnnotationFlipState( 

   int AnnotationIdx,

   bool FlipX,

   bool FlipY

)
public function SetAnnotationFlipState( 

    AnnotationIdx: Integer;

    FlipX: Boolean;

    FlipY: Boolean

): GdPictureStatus; 
public function SetAnnotationFlipState( 

   AnnotationIdx : int,

   FlipX : boolean,

   FlipY : boolean

) : GdPictureStatus;
public: GdPictureStatus SetAnnotationFlipState( 

   int AnnotationIdx,

   bool FlipX,

   bool FlipY

) 
public:

GdPictureStatus SetAnnotationFlipState( 

   int AnnotationIdx,

   bool FlipX,

   bool FlipY

)

Parameters

AnnotationIdx
The 0-based index of the required annotation within the selected page of the handled document. It must be a value from 0 to GetAnnotationCount-1.
FlipX
Set this parameter to true if you want to flip the specified annotation horizontally; otherwise set it to false.
FlipY
Set this parameter to true if you want to flip the specified annotation vertically; otherwise set it to false.

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
Please ensure that you have selected the proper page before starting any annotation related action with the handled document. Annotations are always treated relative to the currently selected page.

At the same, be aware that the method only handles GdPicture/XMP annotations.
