• getMetafileRenderingOptions

  public MetafileRenderingOptions getMetafileRenderingOptions()
  

  Allows to specify how metafiles are treated in the rendered output.

  When MetafileRenderingMode.VECTOR is specified, Aspose.Words renders metafile to vector graphics using its own metafile rendering engine first and then renders vector graphics to the image.

  When MetafileRenderingMode.BITMAP is specified, Aspose.Words renders metafile directly to the image using the GDI+ metafile rendering engine.

  GDI+ metafile rendering engine works faster, supports almost all metafile features but on low resolutions may produce inconsistent result when compared to the rest of vector graphics (especially for text) on the page. Aspose.Words metafile rendering engine will produce more consistent result even on low resolutions but works slower and may inaccurately render complex metafiles.

  The default value for MetafileRenderingMode is MetafileRenderingMode.BITMAP.

  Example:

  Shows how to set the rendering mode for Windows Metafiles.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  
  // Use a DocumentBuilder to insert a .wmf image into the document
  builder.insertImage(getImageDir() + "Windows MetaFile.wmf");
  
  // Save the document as an image while setting different metafile rendering modes,
  // which will be applied to the image we inserted
  ImageSaveOptions options = new ImageSaveOptions(SaveFormat.PNG);
  options.getMetafileRenderingOptions().setRenderingMode(MetafileRenderingMode.VECTOR);
  
  doc.save(getArtifactsDir() + "ImageSaveOptions.WindowsMetaFile.png", options);

• getNumeralFormat/setNumeralFormat

  public int getNumeralFormat() / public void setNumeralFormat(int value)
  

  Gets or sets NumeralFormat used for rendering of numerals. European numerals are used by default. The value of the property is NumeralFormat integer constant.

  If the value of this property is changed and page layout is already built then Document.updatePageLayout() is invoked automatically to update any changes.

  Example:

  Demonstrates how to set the numeral format used when saving to PDF.

  Document doc = new Document();
  DocumentBuilder builder = new DocumentBuilder(doc);
  
  builder.writeln("1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 50, 100");
  
  PdfSaveOptions options = new PdfSaveOptions();
  options.setNumeralFormat(NumeralFormat.EASTERN_ARABIC_INDIC);
  
  doc.save(getArtifactsDir() + "Rendering.SetNumeralFormat.pdf", options);

• getOptimizeOutput/setOptimizeOutput

  public boolean getOptimizeOutput() / public void setOptimizeOutput(boolean value)
  

  Flag indicates whether it is required to optimize output. If this flag is set redundant nested canvases and empty canvases are removed, also neighbor glyphs with the same formatting are concatenated. Note: The accuracy of the content display may be affected if this property is set to true. Default is false.

  Example:

  Shows how to optimize document objects while saving to html.

  Document doc = new Document(getMyDir() + "Rendering.docx");
  
  HtmlFixedSaveOptions saveOptions = new HtmlFixedSaveOptions();
  {
      saveOptions.setOptimizeOutput(false);
  }
  
  doc.save(getArtifactsDir() + "HtmlFixedSaveOptions.OptimizeGraphicsOutput.Unoptimized.html", saveOptions);
  
  saveOptions.setOptimizeOutput(true);
  
  doc.save(getArtifactsDir() + "HtmlFixedSaveOptions.OptimizeGraphicsOutput.Optimized.html", saveOptions);
  
  Assert.assertTrue(new File(getArtifactsDir() + "HtmlFixedSaveOptions.OptimizeGraphicsOutput.Unoptimized.html").length() >
          new File(getArtifactsDir() + "HtmlFixedSaveOptions.OptimizeGraphicsOutput.Optimized.html").length());

• getPageCount/setPageCount

  public int getPageCount() / public void setPageCount(int value)
  

  Gets or sets the number of pages to render when saving to a multipage TIFF or SVG file (for other formats only the first page of the range is saved).

  Default is java.lang.Integer.MAX_VALUE which means all pages of the document will be rendered.

• getTempFolder/setTempFolder

  public java.lang.String getTempFolder() / public void setTempFolder(java.lang.String value)
  

  Specifies the folder for temporary files used when saving to a DOC or DOCX file. By default this property is null and no temporary files are used.

  When Aspose.Words saves a document, it needs to create temporary internal structures. By default, these internal structures are created in memory and the memory usage spikes for a short period while the document is being saved. When saving is complete, the memory is freed and reclaimed by the garbage collector.

  If you are saving a very large document (thousands of pages) and/or processing many documents at the same time, then the memory spike during saving can be significant enough to cause the system to throw System.OutOfMemoryException. Specifying a temporary folder using TempFolder will cause Aspose.Words to keep the internal structures in temporary files instead of memory. It reduces the memory usage during saving, but will decrease the save performance.

  The folder must exist and be writable, otherwise an exception will be thrown.

  Aspose.Words automatically deletes all temporary files when saving is complete.

  Example:

  Shows how to save a document using temporary files.

  Document doc = new Document(getMyDir() + "Rendering.docx");
  
  // We can use a SaveOptions object to set the saving method of a document from a MemoryStream to temporary files
  // While saving, the files will briefly pop up in the folder we set as the TempFolder attribute below
  // Doing this will free up space in the memory that the stream would usually occupy
  DocSaveOptions options = new DocSaveOptions();
  options.setTempFolder(getArtifactsDir() + "TempFiles");
  
  // Ensure that the directory exists and save
  new File(options.getTempFolder()).mkdir();
  
  doc.save(getArtifactsDir() + "DocSaveOptions.TempFolder.doc", options);
