Background Knowledge

When using Spire.PDF for C++ to process an existing PDF document, the origin of the coordinate system is located at the top left corner of the page, with the x-axis extending to the right and the y-axis extending downward. Adding a footer to a page means adding content, such as text, images, shapes and automatic fields, to a specified location in the bottom blank area of the page.

If the blank area is not large enough to accommodate the content you want to add, you can consider increasing the PDF page margins.

Add Footers to an Existing PDF Document in C++

Spire.PDF for C++ offers the PdfCanvas->DrawString() method, PdfCanvas->DrawImage() method, PdfCanvas->DrawLine() method and its similar methods, allowing users to draw text, images and shapes on a PDF page at the specified location. To add dynamic data to the footer, such as page numbers, sections, dates, you need to use the automatic fields. Spire.PDF for C++ provides the PdfPageNumberField class, PdfPageCountField calss, PdfSectionNumberField class etc. to achieve the addition of dynamic information.

The following are the steps to add a footer consisting of an image and page number to a PDF document using Spire.PDF for C++.

• Create a PdfDocument object.
• Load a PDF document using PdfDocument->LoadFromFile() method.
• Load an image using PdfImage::FromFile() method.
• Draw the image on the bottom blank area of a page using PdfPageBase->GetCanvas()->DrawImage() method.
• Create a PdfPageNumberField object, a PdfPageCountField object, and combine them in a PdfCompositeField object to return the string "Page X of Y".
• Draw page number on the bottom blank area of a page using PdfCompositeField->Draw() method.
• Save the document to another PDF file using PdfDocument->SaveToFile() method.

    //Create a composite field to combine page count field and page number field in a single string
    intrusive_ptr<PdfCompositeField> compositeField = new PdfCompositeField(font, brush, L"Page {0} of {1}", list);

    //Get the text size
    intrusive_ptr<SizeF> fontSize = font->MeasureString(compositeField->GetText());

    //Get the page size
    intrusive_ptr<SizeF> pageSize = doc->GetPages()->GetItem(0)->GetSize();

    //Set the position of the composite field
    compositeField->SetLocation(new PointF((pageSize->GetWidth() - fontSize->GetWidth()) / 2, pageSize->GetHeight() - 45));

    //Loop through the pages in the document
    for (int i = 0; i < doc->GetPages()->GetCount(); i++)
    {
        //Get a specific page
        intrusive_ptr<PdfPageBase> page = doc->GetPages()->GetItem(i);

        //Draw the image on the bottom blank area
        page->GetCanvas()->DrawImage(footerImage, 55, pageSize->GetHeight() - 65, pageSize->GetWidth() - 110, 50);

        //Draw the composite field on the bottom blank area
        compositeField->Draw(page->GetCanvas(),0,0);
    }

    //Save to file
    doc->SaveToFile(L"AddFooter.pdf");
