Change page orientation Leave feedback

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 stream;
• 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 });

using (Merger merger = new Merger(filePath))
{
    merger.ChangeOrientation(orientationOptions);
    merger.Save(filePathOut);
}

When no page numbers are specified, the orientation of every page is changed. This applies to PDF, XPS, Word processing, spreadsheet, Visio and presentation documents.

The following code sample demonstrates how to change the orientation of all document pages:

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

OrientationOptions orientationOptions = new OrientationOptions(OrientationMode.Landscape);

using (Merger merger = new Merger(filePath))
{
    merger.ChangeOrientation(orientationOptions);
    merger.Save(filePathOut);
}
