wkhtmltopdf page-break-after有空格(wkhtmltopdf page-break-after have whitespace)

 我使用WKHTMLTOPDF从打印机友好的网页生成PDF 。 我从版本0.10.0 rc2升级到0.12.1 （带有修补的qt），但现在我使用CSS属性，如page-break-before:always; 它插入一堆空格 ，并且page-breake-inside:avoid; 不起作用，这很神奇。 
 
 我用这个电话： 
 
/usr/local/bin/wkhtmltopdf --encoding 'UTF-8' 'page-to-print' '/tmp/PDFV59OZt'
 
 我曾尝试使用和不使用--print-media-type和--no-print-media-type 。 
 
 当我在浏览器中呈现打印机友好页面时，以及当我尝试打印它时（在我制作pdf之前）它可以正常工作。 
 
 我的CSS的例子： 
 
//if i want to make a static page-break between two elements
page-break{
    page-break-after:always;
    clear:both;
    display:block;
}
//Avoid cutting images
img{
    display:block;
    page-break-before:auto;
    page-break-after:auto;
    page-break-inside:avoid;
}
//avoid cutting text
p,em,li,span,tr{ 
    page-break-inside:avoid; 
}
 
 只有分页符号：总是; 工作，但它插入一堆白色空间。 有没有人对此有任何想法？ 

I use WKHTMLTOPDF to generate a PDF from a printer-friendly webpage. I upgraded from version 0.10.0 rc2 to 0.12.1(with patched qt) but now when I use the CSS properties like page-break-before:always; it inserts a bunch of whitespace, and the page-breake-inside:avoid; doesn't work, it's magic.
 
I use this call: 
 
/usr/local/bin/wkhtmltopdf --encoding 'UTF-8' 'page-to-print' '/tmp/PDFV59OZt'
 
I have tried with and without both --print-media-type and --no-print-media-type.
 
When I render the printer-friendly page in my browser, and when I try to print it (before I make it a pdf) it works fine. 
 
examples of my CSS:
 
//if i want to make a static page-break between two elements
page-break{
    page-break-after:always;
    clear:both;
    display:block;
}
//Avoid cutting images
img{
    display:block;
    page-break-before:auto;
    page-break-after:auto;
    page-break-inside:avoid;
}
//avoid cutting text
p,em,li,span,tr{ 
    page-break-inside:avoid; 
}
 
Only page-break-after:always; works, but it inserts a bunch of white-space. Does anyone have any ideas for this?
