Public API and Backward Incompatible Changes

This section lists public API changes that were introduced in Aspose.Words 18.3. It includes not only new and obsoleted public methods, but also a description of any changes in the behavior behind the scenes in Aspose.Words which may affect existing code. Any behavior introduced that could be seen as a regression and modifies existing behavior is especially important and is documented here.

Supported Dynamic Coloring of Chart Series and Individual Series Points for LINQ Reporting Engine

Related issue: WORDSNET-15007

The “Using Charts to Represent Sequential Data” section and its subsections in the engine’s documentation were updated to describe the change.

PdfSaveOptions.EscapeUri Property Added

Related issue: WORDSNET-16121

The following property has been added to the PdfSaveOptions class:

/// <summary>
/// A flag specifying whether URI should be escaped before writing.
/// </summary>
/// <remarks>
/// Note that if this option is set to <c>false</c> hyperlinks are written "as is",
/// so valid (escaped) URI should be provided in document's model.
/// <para>The default value is <c>true</c>.</para>
/// </remarks>
public bool EscapeUri

Set this property to false if you are sure that hyperlinks in document’s model are already escaped:

Document doc = new Document ("in.docx");
PdfSaveOptions options = new PdfSaveOptions ();
options.EscapeUri = false;
doc.Save("out.pdf", options);

Added Support of CssClassNamesPrefix in HtmlSaveOptions

Related issue: WORDSNET-16335

The following property has been added to the HtmlSaveOptions class:


/// <summary>
/// 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.
/// </summary>
/// <remarks>
/// <para>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.</para>
/// <para>If the value is not <c>null</c> or empty, it must be a valid CSS identifier.</para>
/// </remarks>
/// <exception cref="ArgumentException">The value is not empty and is not a valid CSS identifier.</exception>
public string CssClassNamePrefix
    get { return mCssClassNamesPrefix; }
        if (StringUtil.HasChars(value) && !CssEscape.IsValidIdentifier(value))
            throw new ArgumentException("The class name prefix must be a valid CSS identifier.");
        mCssClassNamesPrefix = value;
