How to merge TIFF files in vertical mode

The following example demonstrates how to merge image files in vertical mode with several lines of C# code:

  • Create an instance of Merger class and pass source image file path as a constructor parameter. You may specify absolute or relative file path as per your requirements.
  • Create an instance of ImageJoinOptions class and pass enum value of ImageJoinMode as a constructor parameter.
  • Add another image file to merge with Join method and pass instance of ImageJoinOptions class as a method parameter. Repeat this step for other image documents you want to merge.
  • Call Merger class Save method and specify the filename for the merged image file as parameter.
// Load the source image file
using (Merger merger = new Merger(@"c:\sample1.tiff"))
    // Define image join options with vertical join mode
    ImageJoinOptions joinOptions = new ImageJoinOptions(ImageJoinMode.Vertical);
    // Add another image file to merge
    merger.Join(@"c:\sample2.tiff", joinOptions);
    // Add next image file to merge
    merger.Join(@"c:\sample3.tiff", joinOptions);
    // Merge image files and save result

Result merged TIFF image
