Add Pages to PDF Document

Add Page in a PDF File

The provided Go code snippet demonstrates how to perform the Add Page at the end of the PDF operation using the Aspose.PDF library.

1. The Open function allows the program to load an existing PDF file (sample.pdf) for manipulation. This is essential for any PDF-related operations, such as editing, adding content, or reading data.
2. The PageAdd method is used to insert a new blank page into the existing PDF document. This is useful for extending a document or preparing it for additional content.
3. The Save method ensures that modifications to the PDF are written back to the file. This step is crucial for persisting the changes, such as the addition of new pages.
4. The Close method is called using defer to release any resources allocated during the PDF operations. This is important for preventing memory leaks and ensuring efficient resource usage.

This snippet is a concise and efficient example of how to use the Aspose.PDF Go library for basic PDF manipulation tasks.

Aspose.PDF for Go 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.

    package main

    import "github.com/aspose-pdf/aspose-pdf-go-cpp"
    import "log"

    func main() {
        // Open(filename string) opens a PDF-document with filename
        pdf, err := asposepdf.Open("sample.pdf")
        if err != nil {
            log.Fatal(err)
        }
        // PageAdd() adds new page in PDF-document
        err = pdf.PageAdd()
        if err != nil {
            log.Fatal(err)
        }
        // Save() saves previously opened PDF-document
        err = pdf.Save()
        if err != nil {
            log.Fatal(err)
        }
        // Close() releases allocated resources for PDF-document
        defer pdf.Close()
    }

Insert Page in a PDF File

The PageInsert method inserts a new page at the specified position. This feature is useful when you need to insert additional pages into an existing document, for example, adding a new section or content to a report or presentation.

    package main

    import "github.com/aspose-pdf/aspose-pdf-go-cpp"
    import "log"

    func main() {
        // Open(filename string) opens a PDF-document with filename
        pdf, err := asposepdf.Open("sample.pdf")
        if err != nil {
            log.Fatal(err)
        }
        // PageInsert(num int32) inserts new page at the specified position in PDF-document
        err = pdf.PageInsert(1)
        if err != nil {
            log.Fatal(err)
        }
        // Save() saves previously opened PDF-document
        err = pdf.Save()
        if err != nil {
            log.Fatal(err)
        }
        // Close() releases allocated resources for PDF-document
        defer pdf.Close()
    }
