Show some code (both the XHTML file and the processing code). – Indubitability

I have a similar problem, when (I think) I add in the html content an image that is too height for the page (A4). The first page is blank and from the second page it start todivide the image in more than one page (that could be good but I would like to remove the first blank page)... And I cant find a way to set a page height based on html content (I think is not possilbe with Itext5). Any idea? – Otolith

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.

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>

That works for me. thanks for saving my hours. I just need add this bit @page { size: a4 portrait; } – Hospice

Be careful with the actual widths and heights. For example if the height of the landscape section in this example is too high, you could end up with an extra blank page at the bottom. I ended up using height: 14cm; width: 25.3cm – Franfranc

@Shivan Dragon How can I avoid a blank page, I want the whole page to is portrait, and the first and second is landscape? – Walke

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.
