Add or Insert Page in a PDF File

Aspose.PDF for C++ lets you insert a page to a PDF document at any location in the file as well as add pages to the end of a PDF file.

Insert Empty Page in a PDF File at Desired Location

The following code sample explains you on how to add page in a PDF document.

1. Create a Document class object with the input PDF file.
2. Call the PageCollection collection’s Insert method with specified index.
3. Save the output PDF

The following code snippet shows you how to insert a page in a PDF file.

using namespace System;
using namespace Aspose::Pdf;
using namespace Aspose::Pdf::Text;


void InsertEmptyPageAtDesiredLocation() {
    // Open document
    String _dataDir("C:\\Samples\\");

    // String for input file name
    String inputFileName("InsertEmptyPage.pdf");

    String outputFileName("InsertEmptyPage_out.pdf");

    auto document = MakeObject<Document>(_dataDir + inputFileName);

    // Insert a empty page in a PDF
    document->get_Pages()->Insert(2);

    // Save output file
    document->Save(_dataDir + outputFileName);
}

In the following code example, you can insert an empty page to the desired location by copying the parameters of the specified page:

void InsertEmptyPageAtDesiredLocation2() {
    // Open document
    String _dataDir("C:\\Samples\\");

    // String for input file name
    String inputFileName("InsertEmptyPage.pdf");

    String outputFileName("InsertEmptyPage_out.pdf");

    auto document = MakeObject<Document>(_dataDir + inputFileName);
    auto page = document->get_Pages()->idx_get(1);
    // Insert a empty page in a PDF
    auto pageNew = document->get_Pages()->Insert(2);

    //copy page parameters from page 1
    pageNew->set_ArtBox(page->get_ArtBox());
    pageNew->set_BleedBox(page->get_BleedBox());
    pageNew->set_CropBox(page->get_CropBox());
    pageNew->set_MediaBox(page->get_MediaBox());
    pageNew->set_TrimBox(page->get_TrimBox());

    // Save output file
    document->Save(_dataDir + outputFileName);
}

Add an Empty Page at the End of a PDF File

Sometimes, you want to ensure that a document ends on an empty page. This topic explains how to insert an empty page at the end of the PDF document.

To insert an empty page at the end of a PDF file:

1. Create a Document class object with the input PDF file.
2. Call the PageCollection collection’s Add method, without any parameters.
3. Save the output PDF using the Save method.

The following code snippet shows you how to insert an empty page at the end of a PDF file.

void AddEmptyPageEnd() {
    // Open document
    String _dataDir("C:\\Samples\\");

    // String for input file name
    String inputFileName("InsertEmptyPageAtEnd.pdf");
    String outputFileName("InsertEmptyPageAtEnd_out.pdf");

    auto document = MakeObject<Document>(_dataDir + inputFileName);

    // Insert an empty page at the end of a PDF file
    document->get_Pages()->Add();

    // Save output file
    document->Save(_dataDir + outputFileName);
}
