Examples

显示如何在 PDF 格式中保存笔记本,并提供指定的选项。

string dataDir = RunExamples.GetDataDir_NoteBook();
   var notebook = new Notebook(dataDir + "Notizbuch �ffnen.onetoc2");
   var notebookSaveOptions = new NotebookPdfSaveOptions();
   var documentSaveOptions = notebookSaveOptions.DocumentSaveOptions;
   documentSaveOptions.PageSplittingAlgorithm = new KeepSolidObjectsAlgorithm();
   dataDir += "ConvertToPDF_out.pdf";
   notebook.Save(dataDir, notebookSaveOptions);

显示如何将文档发送到打印机,使用默认的 Windows 对话与指定的选项。

string dataDir = RunExamples.GetDataDir_LoadingAndSaving();
   var document = new Aspose.Note.Document(dataDir + "Aspose.one");
   var printerSettings = new PrinterSettings()
   {
      FromPage = 0,
      ToPage = 10
   };
   printerSettings.DefaultPageSettings.Landscape = true;
   printerSettings.DefaultPageSettings.Margins = new System.Drawing.Printing.Margins(50, 50, 150, 50);
   document.Print(new PrintOptions()
   {
      PrinterSettings = printerSettings,
      Resolution = 1200,
      PageSplittingAlgorithm = new KeepSolidObjectsAlgorithm(),
      DocumentName = "Test.one"
   });

当长长的 OneNote 页面存储在 PDF 格式时,它们分为各页。

string dataDir = RunExamples.GetDataDir_LoadingAndSaving();
   Document doc = new Document(dataDir + "Aspose.one");
   var pdfSaveOptions = new PdfSaveOptions();
   pdfSaveOptions.PageSplittingAlgorithm = new AlwaysSplitObjectsAlgorithm();
   pdfSaveOptions.PageSplittingAlgorithm = new KeepPartAndCloneSolidObjectToNextPageAlgorithm();
   pdfSaveOptions.PageSplittingAlgorithm = new KeepSolidObjectsAlgorithm();
   float heightLimitOfClonedPart = 500;
   pdfSaveOptions.PageSplittingAlgorithm = new KeepPartAndCloneSolidObjectToNextPageAlgorithm(heightLimitOfClonedPart);
   pdfSaveOptions.PageSplittingAlgorithm = new KeepSolidObjectsAlgorithm(heightLimitOfClonedPart);
   pdfSaveOptions.PageSplittingAlgorithm = new KeepSolidObjectsAlgorithm(100);
   pdfSaveOptions.PageSplittingAlgorithm = new KeepSolidObjectsAlgorithm(400);
   dataDir += "UsingKeepSOlidObjectsAlgorithm_out.pdf";
   doc.Save(dataDir);
