) As GdPictureStatus

public GdPictureStatus TiffSwapPages( 
   int ImageID,
   int Page1,
   int Page2
)

public function TiffSwapPages( 
    ImageID: Integer;
    Page1: Integer;
    Page2: Integer
): GdPictureStatus;

public function TiffSwapPages( 
   ImageID : int,
   Page1 : int,
   Page2 : int
) : GdPictureStatus;

public: GdPictureStatus TiffSwapPages( 
   int ImageID,
   int Page1,
   int Page2
)

public:
GdPictureStatus TiffSwapPages( 
   int ImageID,
   int Page1,
   int Page2
)

Parameters

ImageID: A unique image identifier of the GdPicture image representing the editable multipage TIFF image.
Page1: The page number of the one page you want to swap. It must be a value from 1 to GdPictureImaging.TiffGetPageCount.
Page2: The page number of the other page you want to swap. It must be a value from 1 to GdPictureImaging.TiffGetPageCount.

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.

Likewise, for saving the provided modifications you need to use the GdPictureImaging.TiffSaveMultiPageToFile method.

This method requires the Image Documents component to run.

Example

Swapping two pages in a multipage tiff document.

using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
{
    // LoadInMemory parameter is set to true in order to be able to update the input file.
    int imageID = gdpictureImaging.TiffCreateMultiPageFromFile("multipage.tif", true);
    gdpictureImaging.TiffSwapPages(imageID, 1, 2);
    gdpictureImaging.TiffSaveMultiPageToFile(imageID, "multipage.tif", TiffCompression.TiffCompressionAUTO);
    gdpictureImaging.ReleaseGdPictureImage(imageID);
}
