Document Creation using PDFBox.

Create a Blank PDF This small sample shows how to create a new PDF document using PDFBox.

// Create a new empty document
PDDocument document = new PDDocument();

// Create a new blank page and add it to the document
PDPage blankPage = new PDPage();
document.addPage( blankPage );

// Save the newly created document
document.save("BlankPage.pdf");

// finally make sure that the document is properly closed.
document.close();

Example:

public class Report_PDF {
    
    // Create a new font object selecting one of the PDF base fonts
    static PDFont fontPlain = PDType1Font.HELVETICA;
    static PDFont fontBold = PDType1Font.HELVETICA_BOLD;

    static String saveAs = "D:/Yash/docc1.pdf";
    public static void main(String[] args)throws IOException {
        
        // Create a new empty document
        PDDocument document = new PDDocument();
        
        // Create a new blank page and add it to the document
        PDPage page = new PDPage(PDRectangle.A4);
        document.addPage( page );
        
        getPageSpaces(page);
        
        // Start a new content stream which will "hold" the to be created content
        PDPageContentStream pageCS = new PDPageContentStream(document, page);
        
        try {
            // Define a text content stream using the selected font.
            pageCS.beginText();
            pageCS.setFont( fontBold, 12 );
            //setting the coordinates from where the text will be displayed on the page (first one is the column, second is for row)
            pageCS.newLineAtOffset(15, 750);
            
            //drawPageTitle();
            
            pageCS.showText( "Hello World" );
            
            //contentStream.newLine(); // Must call beginText() before newLine()
            pageCS.endText(); // You must call beginText() before calling endText.
        } finally {
            // Make sure that the content stream is closed:
            pageCS.close();
        }
        // drawBoundingBox(document, page); // https://stackoverflow.com/a/52969119/5081877

        PDPage page2 = new PDPage();
        page2 = customPaperSize(page2);
        document.addPage( page2 );
        
        // Save the results and ensure that the document is properly closed:
        document.save( new File( saveAs ) );
        document.close();
    }
    public static void getPageSpaces(PDPage page) {
        float x_Spaces= page.getMediaBox().getWidth();
        float y_Spaces = page.getMediaBox().getHeight();
        System.out.format("Total Page Cells [X:Width=%f]:[Y:Height=%f]\n", x_Spaces, y_Spaces);
    }
    public static PDPage customPaperSize(PDPage page) { // PDRectangle.A4
        PDRectangle rectangle = new PDRectangle();
        rectangle.setLowerLeftX(20);
        rectangle.setLowerLeftY(20);
        rectangle.setUpperRightX(615); // PAGE_WIDTH
        rectangle.setUpperRightY(815); // PAGE_HEIGHT
        
        page.setMediaBox(rectangle);
        page.setCropBox(rectangle);
        page.setArtBox(rectangle);
        return page;
    }
