Footers von pdf-Dokument

Question

Ich ging entlang this Beispiel von iTextTableFooter.

aber ich bin nicht in der Lage, Fußzeilen richtig einzustellen.

Hier ist ein Bild von meinem Problem: Hier ist mein Code, wo habe ich einen Fehler?

public class App { 

public static final String DEST = "c:/radek-folder/app.pdf"; 
protected int horizontalAlignmentLeft = Element.ALIGN_LEFT; 
protected int horizontalAlignmentCenter = Element.ALIGN_CENTER; 
protected int verticalAlignmentMiddle = Element.ALIGN_MIDDLE; 
protected int verticalAlignmentTop = Element.ALIGN_TOP; 
protected String fontTypeRegular = "c:/radek-folder/font_sitebook.ttf"; 
protected String fontTypeBold = "c:/radek-folder/font_sitebook_bold.ttf"; 
protected float fontSizeRegular = 10f; 
protected float fontSizeLarger = 14f; 
protected float fontSizeLarge = 16f; 

public static void main(String[] args) throws IOException, DocumentException { 
    File file = new File(DEST); 
    file.getParentFile().mkdirs(); 
    new App().createPdf(DEST); 
    System.out.println("done"); 
} 

public class FooterTable extends PdfPageEventHelper { 
    protected PdfPTable footer; 

    public FooterTable(PdfPTable footer) { 
     this.footer = footer; 
    } 

    public void onEndPage(PdfWriter writer, Document document) { 
     footer.writeSelectedRows(0, -1, 36, 64, writer.getDirectContent()); 
    } 
} 

public void createPdf(String dest) throws IOException, DocumentException { 
    float smallColumnWidth = 60; 
    float largeColumnWidth = 105; 
    float gigaColumnWidth = 150; 
    float[] row = { smallColumnWidth, smallColumnWidth, smallColumnWidth, 
      smallColumnWidth, smallColumnWidth, largeColumnWidth, largeColumnWidth, 
      gigaColumnWidth, largeColumnWidth, largeColumnWidth, largeColumnWidth, 
      largeColumnWidth, largeColumnWidth, largeColumnWidth, largeColumnWidth, 
      gigaColumnWidth, largeColumnWidth, largeColumnWidth, largeColumnWidth, 
      largeColumnWidth, largeColumnWidth, largeColumnWidth, largeColumnWidth }; 
    float totalWidth = sumOfrow(row); 
    Document document = new Document(PageSize.A1.rotate()); 
    PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(dest)); 

    float x = document.bottomMargin(); 
    PdfPTable tableFooter = new PdfPTable(1); 
    tableFooter.setTotalWidth(523); 
    PdfPCell cell = new PdfPCell(new Phrase("This is a test document")); 
    cell.setBackgroundColor(BaseColor.ORANGE); 
    tableFooter.addCell(cell); 
    cell = new PdfPCell(new Phrase("This is a copyright notice")); 
    cell.setBackgroundColor(BaseColor.LIGHT_GRAY); 
    tableFooter.addCell(cell); 
    FooterTable event = new FooterTable(tableFooter); 
    writer.setPageEvent(event); 

    document.open(); 
    // Header part 

    PdfPTable mainTable = new PdfPTable(1); 
    mainTable.getDefaultCell().setPadding(0); 
    mainTable.setTotalWidth(totalWidth); 
    mainTable.setLockedWidth(true); 

    PdfPTable subTable1 = new PdfPTable(23); 
    subTable1.setTotalWidth(row); 
    subTable1.setLockedWidth(true); 
    for (int i = 0; i < 200; i++) { 
     addCellToTableCzech(subTable1, horizontalAlignmentCenter, 
       verticalAlignmentMiddle, "Číslo", 23, 1, fontTypeBold, 
       fontSizeRegular); 
    } 

    mainTable.addCell(subTable1); 
    document.add(mainTable); 
    document.close(); 
} 

private float sumOfrow(float[] row) { 
    float result = 0; 
    for (float f : row) { 
     result += f; 
    } 
    return result; 
} 

private static void addCellToTableCzech(PdfPTable datatable, int horizontalAlignment, 
     int verticalAlignment, String value, int colspan, int rowspan, 
     String fontType, float fontSize) { 
    BaseFont base = null; 
    try { 
     base = BaseFont.createFont(fontType, BaseFont.CP1250, BaseFont.EMBEDDED); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
    Font font = new Font(base, fontSize); 
    PdfPCell cell = new PdfPCell(new Phrase(value, font)); 
    cell.setColspan(colspan); 
    cell.setRowspan(rowspan); 
    cell.setHorizontalAlignment(horizontalAlignment); 
    cell.setVerticalAlignment(verticalAlignment); 
    cell.setBorder(PdfPCell.BOX); 
    datatable.addCell(cell); 
} 
} 

Answer 1

Sie sollten marginBottom auf das Dokument gesetzt. Es zeigt den PDF-Inhalt an, wo er enden soll, und lässt die Fußzeile getrennt erscheinen.

Document document = new Document(PageSize.A1.rotate(), 36, 36, 36, 72); 

Ergebnis:
