    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:

    const inputFilePath = `c:/sample.pdf`;
const merger = new groupdocs.merger.Merger(inputFilePath);
const outputPath = `c:/output/result.pdf`;
const java = require('java');
const pageArray = java.newArray('int', [1, 3]);
const extractOptions = new groupdocs.merger.ExtractOptions(pageArray);
merger.extractPages(extractOptions);
merger.save(outputPath);

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

    const inputFilePath = `c:/sample.pdf`;
const merger = new groupdocs.merger.Merger(inputFilePath);
const outputPath = `c:/output/result.pdf`;
const evenPages = groupdocs.merger.RangeMode.EvenPages;
const extractOptions = new groupdocs.merger.ExtractOptions(1, 3, evenPages);
merger.extractPages(extractOptions);
merger.save(outputPath);
