Attached is a simple .NET Core application that shows how to load and merge images into a single output image.

Here is the relevant code:

Code:

static void Merge(MergeFile[] mergeFiles, string outputFile, RasterImageFormat outputFormat)
      {
         using RasterCodecs codecs = new RasterCodecs();
         RasterImage image = null;
         try
         {
            foreach (var mergeFile in mergeFiles)
            {
               if (image == null)
                  image = codecs.Load(mergeFile.FileName, 0, CodecsLoadByteOrder.BgrOrGray, mergeFile.FirstPage, mergeFile.LastPage);
               else
                  image.AddPages(codecs.Load(mergeFile.FileName, 0, CodecsLoadByteOrder.BgrOrGray, mergeFile.FirstPage, mergeFile.LastPage), mergeFile.FirstPage, mergeFile.LastPage);
            }

            codecs.Save(image, outputFile, outputFormat, 0);
         }
         finally
         {
            image.Dispose();
         }
      }

Code:

         MergeFile mergeFile1 = new MergeFile
         {
            FileName = @"C:\Users\Public\Documents\LEADTOOLS Images\ocr1-4.tif",
            FirstPage = 1,
            LastPage = -1
         };

         MergeFile mergeFile2 = new MergeFile
         {
            FileName = @"C:\Users\Public\Documents\LEADTOOLS Images\ocr1-4.tif",
            FirstPage = 1,
            LastPage = -1
         };

         Merge(new MergeFile[] { mergeFile1, mergeFile2 }, @"C:\Temp\out.tif", RasterImageFormat.TifJpeg411);
