getting extra blank pdf page in Flying Saucer/iText

Question

while creating pdf from XHTML by using Flying Saucer/iText, want landscape in every pages ( am using this method ) but am getting extra blank page in initial and end pages, any ideas?

Answer 1

If you want lanscape on every page, don't use any selector on the @page rule.

Just use:

  @page {size: landscape;}

It will apply on the whole document, and won't add blank pages in the document.

Answer 2

If you want to use alternate portrait/landscape layouts in the same document (i.e. first page is portrait and the rest are landscape), you need to specify an actual width and height for each @page rule that also has a selector, otherwise Flying Saucer will generate an extra white page (as per bug).

What worked for me:

CSS:

@page {
    size: a4 portrait;
}  

@page land { size: a4 landscape;}
.landscapePage { page:land; height: 21cm; width: 28.6cm}

HTML:

<div>
    Portrait content here
</div>
<span class="pageBreak"/>
<div class="landscapePage">
    landscape content page 1
    <span class="pageBreak"/>
    landscape content page 2
</div>

Answer 3

For making pdf from .vm file I faced the same issue. In my case removing : width: 100%; height: 100%; from by body{} tag helped get rid of the extra page. Hopefully it might be useful for someone else too.

            t = writer.getDirectContent().createTemplate(30, 16);
            try {
                total = Image.getInstance(t);
               // total.setRole(new PdfName("Artifact"));
            } catch (DocumentException de) {

            PdfPTable footer = new PdfPTable(3);
            try {

                footer.setWidths(new int[]{24, 2, 1});
                footer.setTotalWidth(527);
                footer.setLockedWidth(true);
                footer.getDefaultCell().setFixedHeight(40);
                footer.getDefaultCell().setBorder(Rectangle.TOP);
                footer.getDefaultCell().setBorderColor(Color.LIGHT_GRAY);

                // add copyright
     footer.addCell(new Phrase("", new Font(Font.HELVETICA, 12, Font.BOLD)));
    footer.getDefaultCell().setHorizontalAlignment(Element.ALIGN_RIGHT);
                footer.addCell(new Phrase(String.format("Page %d of", writer.getPageNumber()), new Font(Font.HELVETICA, 8)));
               PdfPCell totalPageCount = new PdfPCell(total);
                totalPageCount.setBorder(Rectangle.TOP);
                totalPageCount.setBorderColor(Color.LIGHT_GRAY);
                System.out.println("TOTAL PageCount:  "+totalPageCount);
                footer.addCell(totalPageCount);  
                // write page
                PdfContentByte canvas = writer.getDirectContent();
                canvas.beginText();
                footer.writeSelectedRows(0,-1, 34, 50, canvas);
                canvas.endText();
            } catch(DocumentException de) {
                throw new ExceptionConverter(de);
            }
        }

@Override
    public void onCloseDocument(PdfWriter writer, Document document) {
         System.out.println("On Close");
        int totalLength = String.valueOf(writer.getPageNumber()).length();
        int totalWidth = totalLength * 5;
        ColumnText.showTextAligned(t, Element.ALIGN_RIGHT,
                new Phrase(String.valueOf(writer.getPageNumber()-1), new Font(Font.HELVETICA, 8)),
                totalWidth, 6, 0);
    }
