I try the code out of the patch and it works, so i think isn't a poppler problem. thanks for all<br><br>Mason Alessandro<br><br><div class="gmail_quote">2011/5/27 alessandro mason <span dir="ltr"><<a href="mailto:mason.alessandro.pec@gmail.com">mason.alessandro.pec@gmail.com</a>></span><br>
<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">I've made some experiments and the program creates the document. If I keep the image size of the tmp Qimage with the PageSize() method returns 0. then I think that the problem is when the program chooses the page from the document->page() method or when creates the QImage from the page->renderToImage method.<div>
