  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.

• 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.

  Example:

  Shows how to pass an option to export HTML tags in a well spaced, human readable format.

  Document doc = new Document(getMyDir() + "Document.docx");
  
  // Enabling the PrettyFormat setting will export HTML in an indented format that is easy to read
  // If this is setting is false (by default) then the HTML tags will be exported in condensed form with no indentation
  HtmlSaveOptions htmlOptions = new HtmlSaveOptions(SaveFormat.HTML);

  // When saving the document as an image, we can use an ImageSaveOptions object to edit various aspects of it
  ImageSaveOptions options = new ImageSaveOptions(SaveFormat.PNG);
  {
      options.setImageBrightness(0.3f);     // 0 - 1 scale, default at 0.5
      options.setImageContrast(0.7f);       // 0 - 1 scale, default at 0.5
      options.setHorizontalResolution(72f); // Default at 96.0 meaning 96dpi, image dimensions will be affected if we change resolution
      options.setVerticalResolution(72f);   // Default at 96.0 meaning 96dpi

• 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);

• getThresholdForFloydSteinbergDithering/setThresholdForFloydSteinbergDithering
