Class HtmlSaveOptions

  • java.lang.Object
  • All Implemented Interfaces:
    java.lang.Cloneable
    public class HtmlSaveOptions 
    extends SaveOptions

Can be used to specify additional options when saving a document into the SaveFormat.HTML, SaveFormat.MHTML or SaveFormat.EPUB format.

Example:

Shows how to specify the folder for storing linked images after saving to .html.
Document doc = new Document(getMyDir() + "Rendering.docx");

File imagesDir = new File(getArtifactsDir() + "SaveHtmlWithOptions");

if (imagesDir.exists())
    imagesDir.delete();

imagesDir.mkdir();

// Set an option to export form fields as plain text instead of HTML input elements.
HtmlSaveOptions options = new HtmlSaveOptions(SaveFormat.HTML);
options.setExportTextInputFormFieldAsText(true);
options.setImagesFolder(imagesDir.getPath());

doc.save(getArtifactsDir() + "HtmlSaveOptions.SaveHtmlWithOptions.html", options);

Example:

Shows how to use a specific encoding when saving a document to .epub.
Document doc = new Document(getMyDir() + "Rendering.docx");

// Use a SaveOptions object to specify the encoding for a document that we will save.
HtmlSaveOptions saveOptions = new HtmlSaveOptions();
saveOptions.setSaveFormat(SaveFormat.EPUB);
saveOptions.setEncoding(StandardCharsets.UTF_8);

// By default, an output .epub document will have all of its contents in one HTML part.
// A split criterion allows us to segment the document into several HTML parts.
// We will set the criteria to split the document into heading paragraphs.
// This is useful for readers who cannot read HTML files more significant than a specific size.
saveOptions.setDocumentSplitCriteria(DocumentSplitCriteria.HEADING_PARAGRAPH);

// Specify that we want to export document properties.
saveOptions.setExportDocumentProperties(true);

doc.save(getArtifactsDir() + "HtmlSaveOptions.Doc2EpubSaveOptions.epub", saveOptions);

Example:

Shows how to split a document into parts and save them.

    // document with all the source document's contents.
    // Set the "DocumentSplitCriteria" property to "DocumentSplitCriteria.SectionBreak" to
    // save our document to multiple HTML files: one for each section.

      • getAllowEmbeddingPostScriptFonts/setAllowEmbeddingPostScriptFonts

        public boolean getAllowEmbeddingPostScriptFonts() / public void setAllowEmbeddingPostScriptFonts(boolean value)
        
        Gets or sets a boolean value indicating whether to allow embedding fonts with PostScript outlines when embedding TrueType fonts in a document upon it is saved. The default value is false.

        Note, Word does not embed PostScript fonts, but can open documents with embedded fonts of this type.

        This option only works when FontInfoCollection.EmbedTrueTypeFonts of the DocumentBase.FontInfos property is set to true.

        Example:

        Shows how to save the document with PostScript font.
        Document doc = new Document();
        DocumentBuilder builder = new DocumentBuilder(doc);

      • getAllowNegativeIndent/setAllowNegativeIndent

        public boolean getAllowNegativeIndent() / public void setAllowNegativeIndent(boolean value)
        
        Specifies whether negative left and right indents of paragraphs are normalized when saving to HTML, MHTML or EPUB. Default value is false.

        When negative indent is not allowed, it is exported as zero margin to HTML. When negative indent is allowed, a paragraph might appear partially outside of the browser window.

        Example:

        Shows how to preserve negative indents in the output .html.
        Document doc = new Document();

        public java.lang.String getCssClassNamePrefix() / public void setCssClassNamePrefix(java.lang.String value)
        
        Specifies a prefix which is added to all CSS class names. Default value is an empty string and generated CSS class names have no common prefix.

        If this value is not empty, all CSS classes generated by Aspose.Words will start with the specified prefix. This might be useful, for example, if you add custom CSS to generated documents and want to prevent class name conflicts.

        If the value is not null or empty, it must be a valid CSS identifier.

        Example:

        Shows how to save a document to HTML, and add a prefix to all of its CSS class names.
        Document doc = new Document(getMyDir() + "Paragraphs.docx");

        public java.lang.String getCssStyleSheetFileName() / public void setCssStyleSheetFileName(java.lang.String value)
        
        Specifies the path and the name of the Cascading Style Sheet (CSS) file written when a document is exported to HTML. Default is an empty string.

        This property has effect only when saving a document to HTML format and external CSS style sheet is requested using CssStyleSheetType.

        If this property is empty, the CSS file will be saved into the same folder and with the same name as the HTML document but with the ".css" extension.

        If only path but no file name is specified in this property, the CSS file will be saved into the specified folder and will have the same name as the HTML document but with the ".css" extension.

        If the folder specified by this property doesn't exist, it will be created automatically before the CSS file is saved.

        Another way to specify a folder where external CSS file is saved is to use ResourceFolder.

        Example:

        public int getCssStyleSheetType() / public void setCssStyleSheetType(int value)
        
        Specifies how CSS (Cascading Style Sheet) styles are exported to HTML, MHTML or EPUB. Default value is CssStyleSheetType.INLINE for HTML/MHTML and CssStyleSheetType.EXTERNAL for EPUB. The value of the property is CssStyleSheetType integer constant.

        Saving CSS style sheet into an external file is only supported when saving to HTML. When you are exporting to one of the container formats (EPUB or MHTML) and specifying CssStyleSheetType.EXTERNAL, CSS file will be encapsulated into the output package.

        public int getDocumentSplitCriteria() / public void setDocumentSplitCriteria(int value)
        
        Specifies how the document should be split when saving to SaveFormat.HTML or SaveFormat.EPUB format. Default is DocumentSplitCriteria.NONE for HTML and DocumentSplitCriteria.HEADING_PARAGRAPH for EPUB. The value of the property is DocumentSplitCriteria integer constant.

        Normally you would want a document saved to HTML as a single file. But in some cases it is preferable to split the output into several smaller HTML pages. When saving to HTML format these pages will be output to individual files or streams. When saving to EPUB format they will be incorporated into corresponding packages.

        A document cannot be split when saving in the MHTML format.

        Example:

        Shows how to use a specific encoding when saving a document to .epub.
        Document doc = new Document(getMyDir() + "Rendering.docx");
        
        // Use a SaveOptions object to specify the encoding for a document that we will save.
        HtmlSaveOptions saveOptions = new HtmlSaveOptions();
        saveOptions.setSaveFormat(SaveFormat.EPUB);
        saveOptions.setEncoding(StandardCharsets.UTF_8);
        
        // By default, an output .epub document will have all of its contents in one HTML part.
        // A split criterion allows us to segment the document into several HTML parts.
        // We will set the criteria to split the document into heading paragraphs.
        // This is useful for readers who cannot read HTML files more significant than a specific size.
        saveOptions.setDocumentSplitCriteria(DocumentSplitCriteria.HEADING_PARAGRAPH);

        public int getDocumentSplitHeadingLevel() / public void setDocumentSplitHeadingLevel(int value)
        
        Specifies the maximum level of headings at which to split the document. Default value is 2.

        When DocumentSplitCriteria includes DocumentSplitCriteria.HEADING_PARAGRAPH and this property is set to a value from 1 to 9, the document will be split at paragraphs formatted using Heading 1, Heading 2 , Heading 3 etc. styles up to the specified heading level.

        By default, only Heading 1 and Heading 2 paragraphs cause the document to be split. Setting this property to zero will cause the document not to be split at heading paragraphs at all.

        Example:

        Shows how to split an output HTML document by headings into several parts.
        Document doc = new Document();

        public int getEpubNavigationMapLevel() / public void setEpubNavigationMapLevel(int value)
        
        Specifies the maximum level of headings populated to the navigation map when exporting to IDPF EPUB format. Default value is 3.

        Navigation map in IDPF EPUB format allows user agents to provide easy way of navigation through the document structure. Usually navigation points correspond to headings in the document. To populate headings up to level N assign this value to EpubNavigationMapLevel.

        By default, three levels of headings are populated: paragraphs of styles Heading 1, Heading 2 and Heading 3. You can set this property to a value from 1 to 9 to request corresponding maximum level. Setting it to zero will reduce navigation map to only document root or roots of document parts.

        Example:

        public boolean getExportCidUrlsForMhtmlResources() / public void setExportCidUrlsForMhtmlResources(boolean value)
        
        Specifies whether to use CID (Content-ID) URLs to reference resources (images, fonts, CSS) included in MHTML documents. Default value is false.

        This option affects only documents being saved to MHTML.

        By default, resources in MHTML documents are referenced by file name (for example, "image.png"), which are matched against "Content-Location" headers of MIME parts.

        This option enables an alternative method, where references to resource files are written as CID (Content-ID) URLs (for example, "cid:image.png") and are matched against "Content-ID" headers.

        In theory, there should be no difference between the two referencing methods and either of them should work fine in any browser or mail agent. In practice, however, some agents fail to fetch resources by file name. If your browser or mail agent refuses to load resources included in an MTHML document (doesn't show images or doesn't load CSS styles), try exporting the document with CID URLs.

        Example:

        Shows how to enable content IDs for output MHTML documents.

        public boolean getExportFontResources() / public void setExportFontResources(boolean value)
        
        Specifies whether font resources should be exported to HTML, MHTML or EPUB. Default is false.

        Exporting font resources allows for consistent document rendering independent of the fonts available in a given user's environment.

        If ExportFontResources is set to true, main HTML document will refer to every font via the CSS 3 @font-face at-rule and fonts will be output as separate files. When exporting to IDPF EPUB or MHTML formats, fonts will be embedded into the corresponding package along with other subsidiary files.

        If ExportFontsAsBase64 is set to true, fonts will not be saved to separate files. Instead, they will be embedded into @font-face at-rules in Base64 encoding.

        Important! When exporting font resources, font licensing issues should be considered. Authors who want to use specific fonts via a downloadable font mechanism must always carefully verify that their intended use is within the scope of the font license. Many commercial fonts presently do not allow web downloading of their fonts in any form. License agreements that cover some fonts specifically note that usage via @font-face rules in CSS style sheets is not allowed. Font subsetting can also violate license terms.

      • getExportGeneratorName/setExportGeneratorName

        public boolean getExportGeneratorName() / public void setExportGeneratorName(boolean value)
        
        When true, causes the name and version of Aspose.Words to be embedded into produced files. Default value is true.
      • getExportHeadersFootersMode/setExportHeadersFootersMode

        public int getExportHeadersFootersMode() / public void setExportHeadersFootersMode(int value)
        
        Specifies how headers and footers are output to HTML, MHTML or EPUB. Default value is ExportHeadersFootersMode.PER_SECTION for HTML/MHTML and ExportHeadersFootersMode.NONE for EPUB. The value of the property is ExportHeadersFootersMode integer constant.

        It is hard to meaningfully output headers and footers to HTML because HTML is not paginated.

        When this property is ExportHeadersFootersMode.PER_SECTION, Aspose.Words exports only primary headers and footers at the beginning and the end of each section.

        When it is ExportHeadersFootersMode.FIRST_SECTION_HEADER_LAST_SECTION_FOOTER only first primary header and the last primary footer (including linked to previous) are exported.

        You can disable export of headers and footers altogether by setting this property to ExportHeadersFootersMode.NONE.

        Example:

        Shows how to omit headers/footers when saving a document to HTML.
        Document doc = new Document(getMyDir() + "Header and footer types.docx");
        
        // This document contains headers and footers. We can access them via the "HeadersFooters" collection.

        // Formats such as .html do not split the document into pages, so headers/footers will not function the same way
        // they would when we open the document as a .docx using Microsoft Word.
        // If we convert a document with headers/footers to html, the conversion will assimilate the headers/footers into body text.
        // We can use a SaveOptions object to omit headers/footers while converting to html.
        HtmlSaveOptions saveOptions =
                new HtmlSaveOptions(SaveFormat.HTML);
        {

        // Open our saved document and verify that it does not contain the header's text.
        doc = new Document(getArtifactsDir() + "HeaderFooter.ExportMode.html");
        
        Assert.assertFalse(doc.getRange().getText().contains("First header"));
      • getExportImagesAsBase64/setExportImagesAsBase64

        public boolean getExportImagesAsBase64() / public void setExportImagesAsBase64(boolean value)
        
        Specifies whether images are saved in Base64 format to HTML, MHTML or EPUB. Default is false.

        When this property is set to true image data is exported directly on the img elements and separate files are not created.

        Example:

        Shows how to embed fonts inside a saved HTML document.
        Document doc = new Document(getMyDir() + "Rendering.docx");
        
        HtmlSaveOptions options = new HtmlSaveOptions();

        }
        
        doc.save(getArtifactsDir() + "HtmlSaveOptions.ExportFontsAsBase64.html", options);

        Example:

        Shows how to save a .html document with images embedded inside it.
        Document doc = new Document(getMyDir() + "Rendering.docx");

      • getExportLanguageInformation/setExportLanguageInformation

        public boolean getExportLanguageInformation() / public void setExportLanguageInformation(boolean value)
        
        Specifies whether language information is exported to HTML, MHTML or EPUB. Default is false.

        When this property is set to true Aspose.Words outputs lang HTML attribute on the document elements that specify language. This can be needed to preserve language related semantics.

        Example:

        Shows how to preserve language information when saving to .html.
        Document doc = new Document();
        DocumentBuilder builder = new DocumentBuilder(doc);

        // If we set the "ExportLanguageInformation" flag to "true",

        public int getExportListLabels() / public void setExportListLabels(int value)
        
        Controls how list labels are output to HTML, MHTML or EPUB. Default value is ExportListLabels.AUTO. The value of the property is ExportListLabels integer constant.

        Example:

        Example:

        Shows how to show out-of-bounds objects in output HTML documents.
        Document doc = new Document();
        DocumentBuilder builder = new DocumentBuilder(doc);

        public boolean getExportPageSetup() / public void setExportPageSetup(boolean value)
        
        Specifies whether page setup is exported to HTML, MHTML or EPUB. Default is false.

        Each Section in Aspose.Words document model provides page setup information via PageSetup class. When you export a document to HTML format you might need to keep this information for further usage. In particular, page setup might be important for rendering to paged media (printing) or subsequent conversion to the native Microsoft Word file formats (DOCX, DOC, RTF, WML).

        In most cases HTML is intended for viewing in browsers where pagination is not performed. So this feature is inactive by default.

        Example:

      • getExportRelativeFontSize/setExportRelativeFontSize

        public boolean getExportRelativeFontSize() / public void setExportRelativeFontSize(boolean value)
        
        Specifies whether font sizes should be output in relative units when saving to HTML, MHTML or EPUB. Default is false.

        In many existing documents (HTML, IDPF EPUB) font sizes are specified in relative units. This allows applications to adjust text size when viewing/processing documents. For instance, Microsoft Internet Explorer has "View->Text Size" submenu, Adobe Digital Editions has two buttons: Increase/Decrease Text Size. If you expect this functionality to work then set ExportRelativeFontSize property to true.

        Aspose Words document model contains and operates only with absolute font size units. Relative units need additional logic to be recalculated from some initial (standard) size. Font size of Normal document style is taken as standard. For instance, if Normal has 12pt font and some text is 18pt then it will be output as 1.5em. to the HTML.

        When this option is enabled, document elements other than text will still have absolute sizes. Also some text-related attributes might be expressed absolutely. In particular, line spacing specified with "exactly" rule might produce unwanted results when scaling text. So the source documents should be properly designed and tested when exporting with ExportRelativeFontSize set to true.

        Example:

        Shows how to use relative font sizes when saving to .html.
        Document doc = new Document();
        DocumentBuilder builder = new DocumentBuilder(doc);

        builder.getFont().setSize(24.0);
        builder.writeln("2x default font size,");
        builder.getFont().setSize(96.0);
        builder.write("8x default font size");
        
        // When we save the document to HTML, we can pass a SaveOptions object
        // to determine whether to use relative or absolute font sizes.
        // Set the "ExportRelativeFontSize" flag to "true" to declare font sizes
        // using the "em" measurement unit, which is a factor that multiplies the current font size. 
        // Set the "ExportRelativeFontSize" flag to "false" to declare font sizes
        // using the "pt" measurement unit, which is the font's absolute size in points.

      • getExportRoundtripInformation/setExportRoundtripInformation

        public boolean getExportRoundtripInformation() / public void setExportRoundtripInformation(boolean value)
        
        Specifies whether to write the roundtrip information when saving to HTML, MHTML or EPUB. Default value is true for HTML and false for MHTML and EPUB.

        Saving of the roundtrip information allows to restore document properties such as tab stops, comments, headers and footers during the HTML documents loading back into a Document object.

        When true, the roundtrip information is exported as -aw-* CSS properties of the corresponding HTML elements.

        When false, causes no roundtrip information to be output into produced files.

        public boolean getExportXhtmlTransitional() / public void setExportXhtmlTransitional(boolean value)
        
        Specifies whether to write the DOCTYPE declaration when saving to HTML or MHTML. When true, writes a DOCTYPE declaration in the document prior to the root element. Default value is false. When saving to EPUB or HTML5 (HtmlVersion.HTML_5) the DOCTYPE declaration is always written.

        Aspose.Words always writes well formed HTML regardless of this setting.

        When true, the beginning of the HTML output document will look like this:

                    <?xml version="1.0" encoding="utf-8" standalone="no" ?>
                    <!DOCTYPE html

        Aspose.Words aims to output XHTML according to the XHTML 1.0 Transitional specification, but the output will not always validate against the DTD. Some structures inside a Microsoft Word document are hard or impossible to map to a document that will validate against the XHTML schema. For example, XHTML does not allow nested lists (UL cannot be nested inside another UL element), but in Microsoft Word document multilevel lists occur quite often.

        Example:

        Shows how to display a DOCTYPE heading when converting documents to the Xhtml 1.0 transitional standard.

      • getFontResourcesSubsettingSizeThreshold/setFontResourcesSubsettingSizeThreshold

        public int getFontResourcesSubsettingSizeThreshold() / public void setFontResourcesSubsettingSizeThreshold(int value)
        
        Controls which font resources need subsetting when saving to HTML, MHTML or EPUB. Default is 0.

        ExportFontResources allows exporting fonts as subsidiary files or as parts of the output package. If the document uses many fonts, especially with large number of glyphs, then output size can grow significantly. Font subsetting reduces the size of the exported font resource by filtering out glyphs that are not used by the current document.

        Font subsetting works as follows:

        • By default, all exported fonts are subsetted.
        • Setting FontResourcesSubsettingSizeThreshold to a positive value instructs Aspose.Words to subset fonts which file size is larger than the specified value.
        • Setting the property to java.lang.Integer.MAX_VALUE suppresses font subsetting.

        Important! When exporting font resources, font licensing issues should be considered. Authors who want to use specific fonts via a downloadable font mechanism must always carefully verify that their intended use is within the scope of the font license. Many commercial fonts presently do not allow web downloading of their fonts in any form. License agreements that cover some fonts specifically note that usage via @font-face rules in CSS style sheets is not allowed. Font subsetting can also violate license terms.

        Example:

        Shows how to work with font subsetting.
        Document doc = new Document();
        DocumentBuilder builder = new DocumentBuilder(doc);
        
        builder.getFont().setName("Arial");
        builder.writeln("Hello world!");
        builder.getFont().setName("Times New Roman");
        builder.writeln("Hello world!");
        builder.getFont().setName("Courier New");
        builder.writeln("Hello world!");
        
        // When we save the document to HTML, we can pass a SaveOptions object configure font subsetting.
        // Suppose we set the "ExportFontResources" flag to "true" and also name a folder in the "FontsFolder" property.
        // In that case, the saving operation will create that folder and place a .ttf file inside
        // that folder for each font that our document uses.
        // Each .ttf file will contain that font's entire glyph set,
        // which may potentially result in a very large file that accompanies the document.
        // When we apply subsetting to a font, its exported raw data will only contain the glyphs that the document is
        // using instead of the entire glyph set. If the text in our document only uses a small fraction of a font's
        // glyph set, then subsetting will significantly reduce our output documents' size.
        // We can use the "FontResourcesSubsettingSizeThreshold" property to define a .ttf file size, in bytes.
        // If an exported font creates a size bigger file than that, then the save operation will apply subsetting to that font. 
        // Setting a threshold of 0 applies subsetting to all fonts,
        // and setting it to "int.MaxValue" effectively disables subsetting.

      • getFontsFolder/setFontsFolder

        public java.lang.String getFontsFolder() / public void setFontsFolder(java.lang.String value)
        
        Specifies the physical folder where fonts are saved when exporting a document to HTML. Default is an empty string.

        When you save a Document in HTML format and ExportFontResources is set to true, Aspose.Words needs to save fonts used in the document as standalone files. FontsFolder allows you to specify where the fonts will be saved and FontsFolderAlias allows to specify how the font URIs will be constructed.

        If you save a document into a file and provide a file name, Aspose.Words, by default, saves the fonts in the same folder where the document file is saved. Use FontsFolder to override this behavior.

        If you save a document into a stream, Aspose.Words does not have a folder where to save the fonts, but still needs to save the fonts somewhere. In this case, you need to specify an accessible folder in the FontsFolder property or provide custom streams via the FontSavingCallback event handler.

        If the folder specified by FontsFolder doesn't exist, it will be created automatically.

        ResourceFolder is another way to specify a folder where fonts should be saved.

        Example:

        Shows how to set folders and folder aliases for externally saved resources that Aspose.Words will create when saving a document to HTML.
        Document doc = new Document(getMyDir() + "Rendering.docx");

        Specifies the name of the folder used to construct font URIs written into an HTML document. Default is an empty string.

        When you save a Document in HTML format and ExportFontResources is set to true, Aspose.Words needs to save fonts used in the document as standalone files. FontsFolder allows you to specify where the fonts will be saved and FontsFolderAlias allows to specify how the font URIs will be constructed.

        If FontsFolderAlias is not an empty string, then the font URI written to HTML will be FontsFolderAlias + <font file name>.

        If FontsFolderAlias is an empty string, then the font URI written to HTML will be FontsFolder + <font file name>.

        If FontsFolderAlias is set to '.' (dot), then the font file name will be written to HTML without path regardless of other options.

        Alternative way to specify the name of the folder to construct font URIs is to use ResourceFolderAlias.

        Example:

        Shows how to set folders and folder aliases for externally saved resources that Aspose.Words will create when saving a document to HTML.

      • getImagesFolder/setImagesFolder

        public java.lang.String getImagesFolder() / public void setImagesFolder(java.lang.String value)
        
        Specifies the physical folder where images are saved when exporting a document to HTML format. Default is an empty string.

        When you save a Document in HTML format, Aspose.Words needs to save all images embedded in the document as standalone files. ImagesFolder allows you to specify where the images will be saved and ImagesFolderAlias allows to specify how the image URIs will be constructed.

        If you save a document into a file and provide a file name, Aspose.Words, by default, saves the images in the same folder where the document file is saved. Use ImagesFolder to override this behavior.

        If you save a document into a stream, Aspose.Words does not have a folder where to save the images, but still needs to save the images somewhere. In this case, you need to specify an accessible folder in the ImagesFolder property or provide custom streams via the ImageSavingCallback event handler.

        If the folder specified by ImagesFolder doesn't exist, it will be created automatically.

        ResourceFolder is another way to specify a folder where images should be saved.

        Example:

        Shows how to specify the folder for storing linked images after saving to .html.
        Document doc = new Document(getMyDir() + "Rendering.docx");
        
        File imagesDir = new File(getArtifactsDir() + "SaveHtmlWithOptions");
        
        if (imagesDir.exists())
            imagesDir.delete();
        
        imagesDir.mkdir();
        
        // Set an option to export form fields as plain text instead of HTML input elements.
        HtmlSaveOptions options = new HtmlSaveOptions(SaveFormat.HTML);
        options.setExportTextInputFormFieldAsText(true);
        options.setImagesFolder(imagesDir.getPath());
        
        doc.save(getArtifactsDir() + "HtmlSaveOptions.SaveHtmlWithOptions.html", options);

      • getImagesFolderAlias/setImagesFolderAlias

        public java.lang.String getImagesFolderAlias() / public void setImagesFolderAlias(java.lang.String value)
        
        Specifies the name of the folder used to construct image URIs written into an HTML document. Default is an empty string.

        When you save a Document in HTML format, Aspose.Words needs to save all images embedded in the document as standalone files. ImagesFolder allows you to specify where the images will be saved and ImagesFolderAlias allows to specify how the image URIs will be constructed.

        If ImagesFolderAlias is not an empty string, then the image URI written to HTML will be ImagesFolderAlias + <image file name>.

        If ImagesFolderAlias is an empty string, then the image URI written to HTML will be ImagesFolder + <image file name>.

        If ImagesFolderAlias is set to '.' (dot), then the image file name will be written to HTML without path regardless of other options.

        Alternative way to specify the name of the folder to construct image URIs is to use ResourceFolderAlias.

        Example:

        Shows how to set folders and folder aliases for externally saved resources that Aspose.Words will create when saving a document to HTML.
        Document doc = new Document(getMyDir() + "Rendering.docx");
        
        HtmlSaveOptions options = new HtmlSaveOptions();
        {
            options.setCssStyleSheetType(CssStyleSheetType.EXTERNAL);
            options.setExportFontResources(true);
            options.setImageResolution(72);
            options.setFontResourcesSubsettingSizeThreshold(0);
            options.setFontsFolder(getArtifactsDir() + "Fonts");
            options.setImagesFolder(getArtifactsDir() + "Images");
            options.setResourceFolder(getArtifactsDir() + "Resources");
            options.setFontsFolderAlias("http://example.com/fonts");

      • getImlRenderingMode/setImlRenderingMode

        public int getImlRenderingMode() / public void setImlRenderingMode(int value)
        
        Gets or sets a value determining how ink (InkML) objects are rendered. The value of the property is ImlRenderingMode integer constant. The default value is ImlRenderingMode.INK_ML.

        This property is used when the document is exported to fixed page formats.

        Example:

        Shows how to render Ink object.
        Document doc = new Document(getMyDir() + "Ink object.docx");
        
        // Set 'ImlRenderingMode.InkML' ignores fall-back shape of ink (InkML) object and renders InkML itself.
        // If the rendering result is unsatisfactory,
        // please use 'ImlRenderingMode.Fallback' to get a result similar to previous versions.
        ImageSaveOptions saveOptions = new ImageSaveOptions(SaveFormat.JPEG);
        {
            saveOptions.setImlRenderingMode(ImlRenderingMode.INK_ML);

      • getMemoryOptimization/setMemoryOptimization

        public boolean getMemoryOptimization() / public void setMemoryOptimization(boolean value)
        
        Gets or sets value determining if memory optimization should be performed before saving the document. Default value for this property is false. Setting this option to true can significantly decrease memory consumption while saving large documents at the cost of slower saving time.
      • getMetafileFormat/setMetafileFormat

        public int getMetafileFormat() / public void setMetafileFormat(int value)
        
        Specifies in what format metafiles are saved when exporting to HTML, MHTML, or EPUB. Default value is HtmlMetafileFormat.PNG, meaning that metafiles are rendered to raster PNG images. The value of the property is HtmlMetafileFormat integer constant.

        Metafiles are not natively displayed by HTML browsers. By default, Aspose.Words converts WMF and EMF images into PNG files when exporting to HTML. Other options are to convert metafiles to SVG images or to export them as is without conversion.

        Some image transforms, in particular image cropping, will not be applied to metafile images if they are exported to HTML without conversion.

        Example:

        Shows how to convert SVG objects to a different format when saving HTML documents.
        String html =
                "<html>\r\n                    <svg xmlns='http://www.w3.org/2000/svg' width='500' height='40' viewBox='0 0 500 40'>\r\n                        <text x='0' y='35' font-family='Verdana' font-size='35'>Hello world!</text>\r\n                    </svg>\r\n                </html>";

        // When we save the document to HTML, we can pass a SaveOptions object
        // to determine how the saving operation handles this object.
        // Setting the "MetafileFormat" property to "HtmlMetafileFormat.Png" to convert it to a PNG image.
        // Setting the "MetafileFormat" property to "HtmlMetafileFormat.Svg" preserve it as a SVG object.

        If this option is set to true, Aspose.Words uses Document.FontSettings to resolve each font family name specified in a source document into the name of an available font family, performing font substitution as required.

        Example:

        Shows how to resolve all font names before writing them to HTML.
        Document doc = new Document(getMyDir() + "Missing font.docx");
        
        // This document contains text that names a font that we do not have.
        Assert.assertNotNull(doc.getFontInfos().get("28 Days Later"));
        
        // If we have no way of getting this font, and we want to be able to display all the text
        // in this document in an output HTML, we can substitute it with another font.
        FontSettings fontSettings = new FontSettings();
        {
            fontSettings.getSubstitutionSettings().getDefaultFontSubstitution().setDefaultFontName("Arial");
            fontSettings.getSubstitutionSettings().getDefaultFontSubstitution().setEnabled(true);
        }
        
        doc.setFontSettings(fontSettings);
        
        HtmlSaveOptions saveOptions = new HtmlSaveOptions(SaveFormat.HTML);
        {
            // By default, this option is set to 'False' and Aspose.Words writes font names as specified in the source document.

      • getResourceFolder/setResourceFolder

        public java.lang.String getResourceFolder() / public void setResourceFolder(java.lang.String value)
        
        Specifies a physical folder where all resources like images, fonts, and external CSS are saved when a document is exported to HTML. Default is an empty string.

        ResourceFolder is the simplest way to specify a folder where all resources should be written. Another way is to use individual properties FontsFolder, ImagesFolder, and CssStyleSheetFileName.

        ResourceFolder has a lower priority than folders specified via FontsFolder, ImagesFolder, and CssStyleSheetFileName. For example, if both ResourceFolder and FontsFolder are specified, fonts will be saved to FontsFolder, while images and CSS will be saved to ResourceFolder.

        If the folder specified by ResourceFolder doesn't exist, it will be created automatically.

        Example:

        Shows how to set folders and folder aliases for externally saved resources that Aspose.Words will create when saving a document to HTML.
        Document doc = new Document(getMyDir() + "Rendering.docx");
        
        HtmlSaveOptions options = new HtmlSaveOptions();
        {
            options.setCssStyleSheetType(CssStyleSheetType.EXTERNAL);
            options.setExportFontResources(true);
            options.setImageResolution(72);
            options.setFontResourcesSubsettingSizeThreshold(0);
            options.setFontsFolder(getArtifactsDir() + "Fonts");
            options.setImagesFolder(getArtifactsDir() + "Images");
            options.setResourceFolder(getArtifactsDir() + "Resources");
            options.setFontsFolderAlias("http://example.com/fonts");
            options.setImagesFolderAlias("http://example.com/images");
            options.setResourceFolderAlias("http://example.com/resources");
            options.setExportOriginalUrlForLinkedImages(true);
        }
        
        doc.save(getArtifactsDir() + "HtmlSaveOptions.FolderAlias.html", options);
        See Also:
        FontsFolder, ImagesFolder, CssStyleSheetFileName
      • getResourceFolderAlias/setResourceFolderAlias

        public java.lang.String getResourceFolderAlias() / public void setResourceFolderAlias(java.lang.String value)
        
        Specifies the name of the folder used to construct URIs of all resources written into an HTML document. Default is an empty string.

        ResourceFolderAlias is the simplest way to specify how URIs for all resource files should be constructed. Same information can be specified for images and fonts separately via ImagesFolderAlias and FontsFolderAlias properties, respectively. However, there is no individual property for CSS.

        ResourceFolderAlias has lower priority than FontsFolderAlias and ImagesFolderAlias. For example, if both ResourceFolderAlias and FontsFolderAlias are specified, fonts' URIs will be constructed using FontsFolderAlias, while URIs of images and CSS will be constructed using ResourceFolderAlias.

        If ResourceFolderAlias is empty, the ResourceFolder property value will be used to construct resource URIs.

        If ResourceFolderAlias is set to '.' (dot), resource URIs will contain file names only, without any path.

        Example:

        Shows how to set folders and folder aliases for externally saved resources that Aspose.Words will create when saving a document to HTML.
        Document doc = new Document(getMyDir() + "Rendering.docx");
        
        HtmlSaveOptions options = new HtmlSaveOptions();
        {
            options.setCssStyleSheetType(CssStyleSheetType.EXTERNAL);
            options.setExportFontResources(true);
            options.setImageResolution(72);
            options.setFontResourcesSubsettingSizeThreshold(0);
            options.setFontsFolder(getArtifactsDir() + "Fonts");

      • getSaveFormat/setSaveFormat

        public int getSaveFormat() / public void setSaveFormat(int value)
        
        Specifies the format in which the document will be saved if this save options object is used. Can be SaveFormat.HTML, SaveFormat.MHTML or SaveFormat.EPUB. The value of the property is SaveFormat integer constant.

        Example:

        Shows how to use a specific encoding when saving a document to .epub.
        Document doc = new Document(getMyDir() + "Rendering.docx");
        
        // Use a SaveOptions object to specify the encoding for a document that we will save.
        HtmlSaveOptions saveOptions = new HtmlSaveOptions();
        saveOptions.setSaveFormat(SaveFormat.EPUB);
        saveOptions.setEncoding(StandardCharsets.UTF_8);
        
        // By default, an output .epub document will have all of its contents in one HTML part.
        // A split criterion allows us to segment the document into several HTML parts.
        // We will set the criteria to split the document into heading paragraphs.
        // This is useful for readers who cannot read HTML files more significant than a specific size.
        saveOptions.setDocumentSplitCriteria(DocumentSplitCriteria.HEADING_PARAGRAPH);
        
        // Specify that we want to export document properties.
        saveOptions.setExportDocumentProperties(true);
        
        doc.save(getArtifactsDir() + "HtmlSaveOptions.Doc2EpubSaveOptions.epub", saveOptions);
      • getScaleImageToShapeSize/setScaleImageToShapeSize

        public boolean getScaleImageToShapeSize() / public void setScaleImageToShapeSize(boolean value)
        
        Specifies whether images are scaled by Aspose.Words to the bounding shape size when exporting to HTML, MHTML or EPUB. Default value is true.

        An image in a Microsoft Word document is a shape. The shape has a size and the image has its own size. The sizes are not directly linked. For example, the image can be 1024x786 pixels, but shape that displays this image can be 400x300 points.

        In order to display an image in the browser, it must be scaled to the shape size. The ScaleImageToShapeSize property controls where the scaling of the image takes place: in Aspose.Words during export to HTML or in the browser when displaying the document.

        When ScaleImageToShapeSize is true, the image is scaled by Aspose.Words using high quality scaling during export to HTML. When ScaleImageToShapeSize is false, the image is output with its original size and the browser has to scale it.

        In general, browsers do quick and poor quality scaling. As a result, you will normally get better display quality in the browser and smaller file size when ScaleImageToShapeSize is true, but better printing quality and faster conversion when ScaleImageToShapeSize is false.

        Example:

        Shows how to disable the scaling of images to their parent shape dimensions when saving to .html.
        Document doc = new Document();
        DocumentBuilder builder = new DocumentBuilder(doc);
        
        // Insert a shape which contains an image, and then make that shape considerably smaller than the image.
        BufferedImage image = ImageIO.read(new File(getImageDir() + "Transparent background logo.png"));
        
        Assert.assertEquals(400, image.getWidth());
        Assert.assertEquals(400, image.getHeight());
        
        Shape imageShape = builder.insertImage(image);
        imageShape.setWidth(50.0);
        imageShape.setHeight(50.0);
        
        // Saving a document that contains shapes with images to HTML will create an image file in the local file system
        // for each such shape. The output HTML document will use <image> tags to link to and display these images.
        // When we save the document to HTML, we can pass a SaveOptions object to determine
        // whether to scale all images that are inside shapes to the sizes of their shapes.
        // Setting the "ScaleImageToShapeSize" flag to "true" will shrink every image
        // to the size of the shape that contains it, so that no saved images will be larger than the document requires them to be.
        // Setting the "ScaleImageToShapeSize" flag to "false" will preserve these images' original sizes,
        // which will take up more space in exchange for preserving image quality.
        HtmlSaveOptions options = new HtmlSaveOptions();
        {
            options.setScaleImageToShapeSize(scaleImageToShapeSize);
        }

      • getTableWidthOutputMode/setTableWidthOutputMode

        public int getTableWidthOutputMode() / public void setTableWidthOutputMode(int value)
        
        Controls how table, row and cell widths are exported to HTML, MHTML or EPUB. Default value is HtmlElementSizeOutputMode.ALL. The value of the property is HtmlElementSizeOutputMode integer constant.

        In the HTML format, table, row and cell elements (<table>, <tr>, <th>, <td>) can have their widths specified either in relative (percentage) or in absolute units. In a document in Aspose.Words, tables, rows and cells can have their widths specified using either relative or absolute units too.

        When you convert a document to HTML using Aspose.Words, you might want to control how table, row and cell widths are exported to affect how the resulting document is displayed in the visual agent (e.g. a browser or viewer).

        Use this property as a filter to specify what table widths values are exported into the destination document. For example, if you are converting a document to EPUB and intend to view the document on a mobile reading device, then you probably want to avoid exporting absolute width values. To do this you need to specify the output mode HtmlElementSizeOutputMode.RELATIVE_ONLY or HtmlElementSizeOutputMode.NONE so the viewer on the mobile device can layout the table to fit the width of the screen as best as it can.

        Example:

        Shows how to preserve negative indents in the output .html.
        Document doc = new Document();
        DocumentBuilder builder = new DocumentBuilder(doc);
        
        // Insert a table with a negative indent, which will push it to the left past the left page boundary.
        Table table = builder.startTable();
        builder.insertCell();
        builder.write("Row 1, Cell 1");
        builder.insertCell();
        builder.write("Row 1, Cell 2");
        builder.endTable();
        table.setLeftIndent(-36);
        table.setPreferredWidth(PreferredWidth.fromPoints(144.0));
        
        builder.insertBreak(BreakType.PARAGRAPH_BREAK);
        
        // Insert a table with a positive indent, which will push the table to the right.
        table = builder.startTable();
        builder.insertCell();
        builder.write("Row 1, Cell 1");

        table.setPreferredWidth(PreferredWidth.fromPoints(144.0));
        
        // When we save a document to HTML, Aspose.Words will only preserve negative indents
        // such as the one we have applied to the first table if we set the "AllowNegativeIndent" flag

      • 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 java.lang.IndexOutOfBoundsException. 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 use the hard drive instead of memory when saving a document.
        Document doc = new Document(getMyDir() + "Rendering.docx");
        
        // When we save a document, various elements are temporarily stored in memory as the save operation is taking place.
        // We can use this option to use a temporary folder in the local file system instead,
        // which will reduce our application's memory overhead.
        DocSaveOptions options = new DocSaveOptions();
        options.setTempFolder(getArtifactsDir() + "TempFiles");
        
        // The specified temporary folder must exist in the local file system before the save operation.
        new File(options.getTempFolder()).mkdir();
        
        doc.save(getArtifactsDir() + "DocSaveOptions.TempFolder.doc", options);
        
        // The folder will persist with no residual contents from the load operation.
        Assert.assertEquals(new File(options.getTempFolder()).listFiles().length, 0);

        Gets or sets a value determining whether or not to use anti-aliasing for rendering.

        The default value is false. When this value is set to true anti-aliasing is used for rendering.

        This property is used when the document is exported to the following formats: SaveFormat.TIFF, SaveFormat.PNG, SaveFormat.BMP, SaveFormat.JPEG, SaveFormat.EMF. When the document is exported to the SaveFormat.HTML, SaveFormat.MHTML and SaveFormat.EPUB formats this option is used for raster images.

        Example:

        Shows how to improve the quality of a rendered document with SaveOptions.
        Document doc = new Document(getMyDir() + "Rendering.docx");
        DocumentBuilder builder = new DocumentBuilder(doc);
        
        builder.getFont().setSize(60.0);
        builder.writeln("Some text.");
        
        SaveOptions options = new ImageSaveOptions(SaveFormat.JPEG);
        
        doc.save(getArtifactsDir() + "Document.ImageSaveOptions.Default.jpg", options);
        
        options.setUseAntiAliasing(true);
        options.setUseHighQualityRendering(true);
        
        doc.save(getArtifactsDir() + "Document.ImageSaveOptions.HighQuality.jpg", options);
      • getUseHighQualityRendering/setUseHighQualityRendering

        public boolean getUseHighQualityRendering() / public void setUseHighQualityRendering(boolean value)
        
        Gets or sets a value determining whether or not to use high quality (i.e. slow) rendering algorithms. The default value is false.

        This property is used when the document is exported to image formats: SaveFormat.TIFF, SaveFormat.PNG, SaveFormat.BMP, SaveFormat.JPEG, SaveFormat.EMF.

        Example:

        Shows how to improve the quality of a rendered document with SaveOptions.
        Document doc = new Document(getMyDir() + "Rendering.docx");
        DocumentBuilder builder = new DocumentBuilder(doc);
        
        builder.getFont().setSize(60.0);
        builder.writeln("Some text.");
        
        SaveOptions options = new ImageSaveOptions(SaveFormat.JPEG);
        
        doc.save(getArtifactsDir() + "Document.ImageSaveOptions.Default.jpg", options);
        
        options.setUseAntiAliasing(true);
        options.setUseHighQualityRendering(true);
        
        doc.save(getArtifactsDir() + "Document.ImageSaveOptions.HighQuality.jpg", options);
