Examples

Quando longas páginas do OneNote são salvas em formato pdf, elas são divididas por páginas.A amostra mostra como configurar a lógica de divisão dos objetos localizados nas pausas da página.

string dataDir = RunExamples.GetDataDir_LoadingAndSaving();
   Document doc = new Document(dataDir + "Aspose.one");
   var pdfSaveOptions = new PdfSaveOptions();
   pdfSaveOptions.PageSplittingAlgorithm = new KeepPartAndCloneSolidObjectToNextPageAlgorithm(100);
   pdfSaveOptions.PageSplittingAlgorithm = new KeepPartAndCloneSolidObjectToNextPageAlgorithm(400);
   dataDir += "PageSplittUsingKeepPartAndCloneSolidObjectToNextPageAlgorithm_out.pdf";
   doc.Save(dataDir);
