Extract pages

GroupDocs.Merger allows to extract pages from source document. The result is a new document that contains only specified pages from the source document.

Here are the steps to extract document pages:

  • Initialize ExtractOptions class with page numbers that should appear in the resultant document;
  • Instantiate Merger object with source document path or stream;
  • Call ExtractPages method and pass ExtractOptions object to it;
  • Call Save method specifying file path to save resultant document.

The following code sample demonstrates how to extract document pages by specifying exact page numbers:

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

ExtractOptions extractOptions = new ExtractOptions(new int[] { 1, 4 }); // Resultant document will contain pages 1 and 4

using (Merger merger = new Merger(filePath))
{
    merger.ExtractPages(extractOptions);
    merger.Save(filePathOut);
}

The following code sample demonstrates how to extract document pages by specifying page numbers range:

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

ExtractOptions extractOptions = new ExtractOptions(1, 3, RangeMode.EvenPages); // Resultant document will contain page 2
using (Merger merger = new Merger(filePath))
{
	merger.ExtractPages(extractOptions);
    merger.Save(filePathOut);
}
