C# Code To Split, Merge Tiff Files

Split the TIFF File
---------------------
filepath--- The Path of the Source TIFF File need to Split.

DestTiffile ---The Path of the Destination Folder, the splited files need to be saved.

        protected void SplitTiff(string filepath)

        {

            int activePage;

            int pages;

            string DestTiffile = dirPath + "\\Images";

            System.Drawing.Image image = System.Drawing.Image.FromFile(filepath + ".tif");

            

            pages = image.GetFrameCount( System.Drawing.Imaging.FrameDimension.Page);

            

            for (int index = 0; index < pages; index++)

            {

            

                activePage = index + 1;

                image.SelectActiveFrame(System.Drawing.Imaging.FrameDimension.Page, index);

                image.Save(DestTiffile + "\\TIFSplit\\TifFile_" + activePage.ToString() + ".tif");

            }

       

        }

Merge the Multiple TIFF Files into one File
--------------------------------------------------
SourceFiles--- The Path of the Source TIFF Files need to Merge.

str_DestinationPath---The Path of the Destination Folder, the Merged file need to be saved.
