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.

true
, pretty formats output where applicable.
Default value is false.
Set to true to make HTML, MHTML, EPUB, WordML, RTF, DOCX and ODT output human readable. Useful for testing or debugging.
Example:
Shows how to pass an option to export HTML tags in a well spaced, human readable format.Document doc = new Document(getMyDir() + "Document.doc"); HtmlSaveOptions htmlOptions = new HtmlSaveOptions(SaveFormat.HTML); // 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. htmlOptions.setPrettyFormat(true); doc.save(getMyDir() + "Document.PrettyFormat Out.html", htmlOptions);

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
The folder must exist and be writable, otherwise an exception will be thrown.
Aspose.Words automatically deletes all temporary files when saving is complete.
getTiffBinarizationMethod/setTiffBinarizationMethod | |
public int getTiffBinarizationMethod() / public void setTiffBinarizationMethod(int value) |
The default value is ImageBinarizationMethod.Threshold.

Example:
Converts a page of a Word document into a TIFF image and uses the CCITT compression.Document doc = new Document(getMyDir() + "Rendering.doc"); ImageSaveOptions options = new ImageSaveOptions(SaveFormat.TIFF); options.setTiffCompression(TiffCompression.CCITT_3); options.setPageIndex(0); options.setPageCount(1); doc.save(getMyDir() + "Rendering.SaveToTiffCompression Out.tiff", options);

true
.
getUseAntiAliasing/setUseAntiAliasing | → inherited from SaveOptions |

getUseHighQualityRendering/setUseHighQualityRendering | → inherited from SaveOptions |
public boolean getUseHighQualityRendering() / public void setUseHighQualityRendering(boolean value) |
false
.
This property is used when the document is exported to image formats:
getWarningCallback/setWarningCallback | → inherited from SaveOptions |
public IWarningCallback getWarningCallback() / public void setWarningCallback(IWarningCallback value) |
This property is obsolete. Please use
Example:
Demonstrates how to implement the IWarningCallback to be notified of any font substitution during document save.public class HandleDocumentWarnings implements IWarningCallback { /** * Our callback only needs to implement the "Warning" method. This method is called whenever there is a * potential issue during document procssing. The callback can be set to listen for warnings generated during document * load and/or document save. */ public void warning(WarningInfo info) { // We are only interested in fonts being substituted. if (info.getWarningType() == WarningType.FONT_SUBSTITUTION) { System.out.println("Font substitution: " + info.getDescription()); } } }
Example:
Demonstrates how to recieve notifications of font substitutions by using IWarningCallback.// Load the document to render. Document doc = new Document(getMyDir() + "Document.doc"); // We can choose the default font to use in the case of any missing fonts. FontSettings.setDefaultFontName("Arial"); // For testing we will set Aspose.Words to look for fonts only in a folder which doesn't exist. Since Aspose.Words won't // find any fonts in the specified directory, then during rendering the fonts in the document will be subsuited with the default // font specified under FontSettings.DefaultFontName. We can pick up on this subsuition using our callback. FontSettings.setFontsFolder("", false); // Create a new class implementing IWarningCallback which collect any warnings produced during document save. HandleDocumentWarnings callback = new HandleDocumentWarnings(); // We assign the callback to the appropriate save options class. In this case, we are going to save to PDF // so we create a PdfSaveOptions class and assign the callback there. PdfSaveOptions saveOptions = new PdfSaveOptions(); saveOptions.setWarningCallback(callback); // Pass the save options along with the save path to the save method. doc.save(getMyDir() + "Rendering.MissingFontNotification Out.pdf", saveOptions);
