Change page orientation

GroupDocs.Merger allows to set Portrait or Landscape page orientation for specific or all document pages.

Here are the steps to change page orientation:

• Initialize OrientationOptions class with desired orientation mode and page numbers;
• Instantiate Merger object with source document path or InputStream;
• Call changeOrientation method and pass OrientationOptions object to it;
• Call save method specifying file path to save resultant document.

The following code sample demonstrates how to change page orientation:

String filePath = "c:\sample.docx";
String filePathOut = "c:\output\result.docx";

OrientationOptions orientationOptions = new OrientationOptions(OrientationMode.Landscape, new int[] { 3, 4 });

Merger merger = new Merger(filePath);
merger.changeOrientation(orientationOptions);
merger.save(filePathOut);
