Extract pages

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 InputStream;
• 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

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

Merger merger = new Merger(filePath);
merger.extractPages(extractOptions);
merger.save(filePathOut);
