Pdfbox在具有不同页面范围和文件名的多个文件中拆分PDF

Question

I have a question to Apache PDFBox. Is it possible to split a pdf file in diffrent files with diffrent page ranges and file names?

Example:

• page 1 - 5 filename: part1.pdf
• page 6 filename: part2.pdf
• page 7 - 10 filename: part3.pdf
• ...

This might be too late but here's a solution for future readers.

Using PDFBOX 2.0+ :

private static void splitPdf(int startIndex, int endIndex) {
    if (document.getNumberOfPages() > 20) {
        System.out.println(document.getDocumentInformation().getTitle());
        try {
            Splitter splitter = new Splitter();
            splitter.setSplitAtPage(endIndex - startIndex + 1);
            List<PDDocument> splittedList = splitter.split(document);
            int start = 1, end = 20;
            for (PDDocument doc : splittedList) {
                doc.save("/home/Downloads/pdfs/" + document.getDocumentInformation().getTitle()
                        + "_" + start + "_" + end + ".pdf");
                start = end + 1;
                end += 20;
                if (end > document.getNumberOfPages()) {
                    end = document.getNumberOfPages();
                }
                doc.close();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

And I am calling this method as:

splitPdf(1, 20)

Explanation :

Here, I am splitting pdfs to 20 pages. Feel free to change the number as your need.

Here is the documentation for .setSplitAtPage() :

https://pdfbox.apache.org/docs/2.0.3/javadocs/org/apache/pdfbox/multipdf/Splitter.html

From docs: This will tell the splitting algorithm where to split the pages. The default is 1, so every page will become a new document. If it was two then each document would contain 2 pages. If the source document had 5 pages it would split into 3 new documents, 2 documents containing 2 pages and 1 document containing one page.

The start and end variables are used just for file names.

Hope this helps!

This is my answer. With me it good working

    private static void splitPdf(PDDocument document, String fileName, int fromPage, int toPage) {
    if (document.getNumberOfPages() > 20) {
        System.out.println(document.getDocumentInformation().getTitle());
        try {
            Splitter splitter = new Splitter();
            splitter.setStartPage(fromPage);
            splitter.setEndPage(toPage);
            splitter.setSplitAtPage(toPage); 
            List<PDDocument> splittedList = splitter.split(document);
            for (PDDocument doc : splittedList) {
                doc.save(PATH_SAVE_FILE + fileName + ".pdf"); 
                doc.close();                    
            }                 
            System.out.println("Save successful file : " + fileName);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

The main statement you may be missing is:

splitter.setEndPage(toPage);

Answer 3

Hope this will help

int fromPage = 1;
int toPage = 5 ;

File pdfFile = new File("<filePath-to-main-pdf>");
pdfDocument = PDDocument.load(pdfFile);

Splitter splitter = new Splitter();

splitter.setStartPage(fromPage);
splitter.setEndPage(toPage);
splitter.setSplitAtPage(toPage - fromPage +1 );

List<PDDocument> lst =splitter.split(pdfDocument);

PDDocument pdfDocPartial = lst.get(0);
File f = new File("<filePath-WithName>");
pdfDocPartial.save(f);

    int numberOfPagesFileShouldHave = 50;
    PDDocument document = PDDocument.load(inputFile);            
    if (document.getNumberofPages() > 50) {
        try {
            int divideIntoFiles = Math.abs(document.getNumberOfPages() / numberOfPagesFileShouldHave) + 1;
            System.out.println("Divide Into FIles =" + divideIntoFiles);
            int startIndex = 1;
            int endIndex= numberOfPagesFileShouldHave; 
                for (int i = 1; i < divideIntoFiles; i++) {
                    Splitter splitter =  new Splitter();
                splitter.setStartPage(startIndex);
                splitter.setEndPage(endIndex);
                splitter.setSplitAtPage(endIndex);
                List <PDDocument> splittedList = splitter.split(document);
                for (PDDocument doc : splittedList) {
                    doc.save("C:\\Work2022\\_darksiderg" + " " + startIndex + endIndex + ".pdf");
                    doc.close();
                    startIndex  = endIndex + 1;
                    endIndex = endIndex + numberOfPagesFileShouldHave;
                }
                }
        }catch (Exception e) {
                    e.printStackTrace();
                }
                
            }
