If you are planning to upgrade from older version of Aspose.Words to the current version, we would strongly suggest you to check the Public API and Backward Incompatible Changes section to know what APIs are changed so far.

Here is a look at just a few of the biggest features and API changes in this month’s release.

Added Public Property HtmlSaveOptions.ExportFontsAsBase64

We have introduced new property HtmlSaveOptions.ExportFontsAsBase64 in Aspose.Words 17.2.0. This property allows user to embed fonts resources to HTML in Base64 encoding. 

/// <summary>
/// Specifies whether fonts resources should be embedded to HTML in Base64 encoding.
/// Default is <c>false</c>.
/// </summary>
/// <remarks>
/// <p>By default, fonts are written to separate files. If this option is set to <c>true</c>, fonts will be embedded
/// into the document's CSS in Base64 encoding.</p>
/// </remarks>
public bool ExportFontsAsBase64 {
    get { return mExportFontsAsBase64; }
    set { mExportFontsAsBase64 = value; }
}

Use Case:

HtmlSaveOptions saveOptions = new HtmlSaveOptions();
saveOptions.ExportFontResources = true;
saveOptions.ExportFontsAsBase64 = true;
doc.Save(fileName, saveOptions);

Added Public Property HtmlSaveOptions.ResourceFolder

We have introduced new property HtmlSaveOptions.ResourceFolder in Aspose.Words 17.2.0. This property is used to Specify a physical folder where all resources like images, fonts, and external CSS are saved when a document is exported to HTML. The default value of this property is an empty string.

/// <summary>
/// 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.
/// </summary>
/// <remarks>
/// <p><see cref="ResourceFolder"/> is the simplest way to specify a folder where all resources should be written.
/// Another way is to use individual properties <see cref="FontsFolder"/>, <see cref="ImagesFolder"/>,
/// and <see cref="CssStyleSheetFileName"/>.</p>
///
/// <p><see cref="ResourceFolder"/> has a lower priority than folders specified via <see cref="FontsFolder"/>,
/// <see cref="ImagesFolder"/>, and <see cref="CssStyleSheetFileName"/>. For example, if both <see cref="ResourceFolder"/>
/// and <see cref="FontsFolder"/> are specified, fonts will be saved to <see cref="FontsFolder"/>, while images and CSS
/// will be saved to <see cref="ResourceFolder"/>.</p>
///
/// <p>If the folder specified by <see cref="ResourceFolder"/> doesn't exist, it will be created automatically.</p>
///
/// <seealso cref="FontsFolder"/>
/// <seealso cref="ImagesFolder"/>
/// <seealso cref="CssStyleSheetFileName"/>
/// </remarks>
public string ResourceFolder
{
    get { return mResourceFolder; }
    set
    {
        ArgumentUtil.CheckNotNull(value, "ResourceFolder");
        mResourceFolder = value;
    }
}

Use Case:

Document doc = new Document(@"C:\Test.docx");
HtmlSaveOptions saveOptions = new HtmlSaveOptions();
saveOptions.CssStyleSheetType = CssStyleSheetType.External;
saveOptions.ExportFontResources = true;
saveOptions.ResourceFolder = @"C:\Resources";
doc.Save(@"C:\Test.html", saveOptions);

Added Public Property HtmlSaveOptions.ResourceFolderAlias

We have introduced new property HtmlSaveOptions.ResourceFolderAlias in Aspose.Words 17.2.0. This property is used to specify the name of the folder used to construct URIs of all resources written into an HTML document. The default value of this property is an empty string. 

/// <summary>
/// Specifies the name of the folder used to construct URIs of all resources written into an HTML document.
/// Default is an empty string.
/// </summary>
/// <remarks>
/// <p><see cref="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 <see cref="ImagesFolderAlias"/>
/// and <see cref="FontsFolderAlias"/> properties, respectively. However, there is no individual property for CSS.</p>
///
/// <p><see cref="ResourceFolderAlias"/> has lower priority than <see cref="FontsFolderAlias"/>
/// and <see cref="ImagesFolderAlias"/>. For example, if both <see cref="ResourceFolderAlias"/>
/// and <see cref="FontsFolderAlias"/> are specified, fonts' URIs will be constructed using <see cref="FontsFolderAlias"/>,
/// while URIs of images and CSS will be constructed using <see cref="ResourceFolderAlias"/>.</p>
///
/// <p>If <see cref="ResourceFolderAlias"/> is empty, the <see cref="ResourceFolder"/> property value will be used
/// to construct resource URIs.</p>
///
/// <p>If <see cref="ResourceFolderAlias"/> is set to '.' (dot), resource URIs will contain file names only, without
/// any path.</p>
///
/// <seealso cref="ResourceFolder"/>
/// <seealso cref="FontsFolderAlias"/>
/// <seealso cref="ImagesFolderAlias"/>
/// </remarks>
public string ResourceFolderAlias
{
    get { return mResourceFolderAlias; }
    set
    {
        ArgumentUtil.CheckNotNull(value, "ResourceFolderAlias");
        mResourceFolderAlias = value;
    }
}

Use Case:

Document doc = new Document("C:\Test.docx");
HtmlSaveOptions saveOptions = new HtmlSaveOptions();
saveOptions.setCssStyleSheetType(CssStyleSheetType.External);
saveOptions.setExportFontResources(true);
saveOptions.setResourceFolder("C:\Resources");
saveOptions.setResourceFolderAlias("http://example.com/resources");
doc.save("C:\Test.html", saveOptions);
