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 class="gmail_quote">2011/5/26 Albert Astals Cid <<a href="mailto:aacid@kde.org">aacid@kde.org</a>> <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> A Thursday, May 26, 2011, alessandro mason va escriure: <div><div></div><div class="h5">> Hi, > I made a patch for PureData tha includes this code: > > poppler::poppler() > { > //ctor > } > poppler::poppler(const char* file) > {//ctor > loaded=loadedpage=save=true; > document= Poppler::Document::load(file);//open the document file > if (!document || document->isLocked()) { > loaded=false; > delete document; > } > > }//end cosntructor > > void poppler::selPage(int page){ > poppler::pdfPage=document->page(1); // Document starts at page 0 > if (pdfPage == 0) { > loadedpage=false; > } > // Generate a QImage of the rendered page > loaded=true; > tmp = poppler::pdfPage->renderToImage(72,72,-1,-1,-1,-1);// > if (tmp.isNull()) { > loaded=false; > } > > filename=QString("page.bmp"); > save=tmp.save(filename,"BMP",50);//savepage > > } > > poppler::~poppler() > { > //dtor > delete poppler::pdfPage; > delete poppler::document; > } > > With Debian this code works, but now with Ubuntu 11.4 doesn't work because > it doesn't save the image. > Can anyone help me? </div></div>Can you give more data? You have some variables there to check for errors, is any of them failing?
