Public API and Backward Incompatble Changes

This section lists public API changes that were introduced in Aspose.Words 17.10. 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.

Added CompareOptions.Target Property and Enumeration ComparisonTargetType

Related issue WORDSNET-15681.

Public property added to the CompareOptions class to provide ability to determine base document upon documents comparison. 

For example, this option together with IgnoreFormatting setting determines which document has to be used as formatting source for ranges of equal text.

/// <summary>
/// Specifies which document shall be used as a target during comparison.
/// The value of the property is ComparisonTargetType integer constant.
/// </summary>
public int getTarget()
void setTarget(int value)

ssible values described by the following enumeration

/// <summary>
/// Allows to specify base document which will be used during comparison.  Default value is <see cref="Current" />.
///Default value is CURRENT.
/// </summary>
/// <remarks>
/// Relates to Microsoft Word "Show changes in" option in "Compare Documents" dialog box.
/// </remarks>
public class ComparisonTargetType
  /// <summary>
  /// This document is used as a base during comparison.
  /// </summary>
public static final int CURRENT = 0
  /// <summary>
  /// Other document is used as a base during comparison.
  /// </summary>
public static final int NEW = 1
// Use case.
Document docA = new Document(pathA);
Document docB = new Document(pathB);
CompareOptions options = new CompareOptions();
options.setTarget(ComparisonTargetType.NEW);, "am", new Date(), options);

LINQ Reporting Engine Supports Dynamic Chart Series Removal

Related Issue: WORDSNET-15442

The “Using Charts to Represent Sequential Data” section of the engine’s documentation was updated to describe the change.

Added Public Methods to Add and Remove Replies to Comment

Related issue WORDSNET-9959

Implemented public API to add/remove comment replies. The following methods have been added to the Comment class:

/// <summary>
/// Adds a reply to this comment.
/// </summary>
/// <param name="author">The author name for the reply.</param>
/// <param name="initial">The author initials for the reply.</param>
/// <param name="dateTime">The date and time for the reply.</param>
/// <param name="text">The reply text.</param>
/// <returns>The created <see cref="Comment"/> node for the reply.</returns>
/// <remarks>
/// Due to the existing MS Office limitations only 1 level of replies is allowed in the document.
/// An exception of type <see cref="InvalidOperationException"/> will be raised if this method is
/// called on the existing Reply comment.
/// </remarks>
public Comment addReply(string author, string initial, java.util.Date dateTime, string text);
/// <summary>
/// Removes the specified reply to this comment.
/// </summary>
/// <param name="reply">The comment node of the deleting reply.</param>
/// <remarks>All constituent nodes of the reply will be deleted from the document.</remarks>
public void removeReply(Comment reply);
/// <summary>
/// Removes all replies to this comment.
/// </summary>
/// <remarks>All constituent nodes of the replies will be deleted from the document.</remarks>
public void removeAllReplies();

UC to add/remove replies:

Document doc = new Document(fileName);
Comment comment = (Comment)doc.getChild(NodeType.COMMENT, 0, true);
comment.addReply("John Doe", "JD", new Date(2017, 9, 25, 12, 15, 0), "New reply");;

Ability to Get and Set Number of Footnote Layout Columns is Implemented

Related issue: WORDSNET-14958

The following property has been added into the FootnoteOptions class:

/// <summary>
/// Specifies the number of columns with which the footnotes area is formatted.
/// </summary>
/// <remarks>
/// If this property has the value of 0, the footnotes area is formatted with a number of columns based on
/// the number of columns on the displayed page. The default value is 0.
/// </remarks>
public int getColumns()
public void setColumns(int value)


Document doc = new Document(fileName);

The Document.EndnoteOptions and PageSetup.EndnoteOptions properties have been changed to be of the EndnoteOptions type. This new EndnoteOptions class has the same properties as FootnoteOptions except the Columns property:

/// <summary>
/// Represents the endnote numbering options for a document or section.
/// </summary>
public class EndnoteOptions
    /// <summary>
    /// Specifies the endnotes position. The value of the property is EndnotePosition integer constant.
    /// </summary>
    public int getPosition()
    public void setPosition(int value)
    /// <summary>
    /// Specifies the number format for automatically numbered endnotes. The value of the property is NumberStyle integer constant.
    /// </summary>
    public int getNumberStyle()
    public void setNumberStyle(int value)
    /// <summary>
    /// Specifies the starting number or character for the first automatically numbered endnotes.
    /// </summary>
    public int getStartNumber()
    public void setStartNumber(int value)
    /// <summary>
    /// Determines when automatic numbering restarts. The value of the property is FootnoteNumberingRule integer constant.
    /// </summary>
    public int getRestartRule()
    public void setRestartRule(int value)

The similar Position property of the FootnotePosition type is added into the FootnoteOptions class. The property should be used instead of the obsolete Location property.

The new public enum types FootnotePosition and EndnotePosition have the following items:

/// <summary>
/// Defines the footnote position.
/// </summary>
public class FootnotePosition
    /// <summary>
    /// Footnotes are output at the bottom of each page.
    /// </summary>
    /// <summary>
    /// Footnotes are output beneath text on each page.
    /// </summary>
/// <summary>
/// Defines the endnote position.
/// </summary>
public class EndnotePosition
    /// <summary>
    /// Endnotes are output at the end of the section.
    /// </summary>
    /// <summary>
    /// Endnotes are output at the end of the document.
    /// </summary>

Provided API Similar to SignatureSet.AddSignatureLine Method (Office)

Related issue: WORDSNET-14984

Added public property ProviderId to the SignOptions class.

// Specifies the class ID of the signature provider.
public java.util.UUID getProviderId()
public void setProviderId(java.util.UUID value)

And also added public property ProviderId to the SignatureLine class.

// Gets or sets signature provider identifier for this signature line.
public java.util.UUID getProviderId()
public void setProviderId(java.util.UUID value)

UC1 - existing signature line:

Document doc = new Document("pathToDocument.docx");
SignatureLine signatureLine = ((Shape)doc.getFirstSection().getBody().getChild(NodeType.SHAPE, 0, true)).getSignatureLine();
SignOptions signOptions = new SignOptions();
CertificateHolder certHolder = CertificateHolder.create("pathToCert.pfx", "certPassword");
DigitalSignatureUtil.sign("pathToSrcFile.docx", "pathToDstFile.docx", certHolder, signOptions);

C2 - creating new signature line:

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
SignatureLine signatureLine = builder.insertSignatureLine(new SignatureLineOptions()).getSignatureLine();
SignOptions signOptions = new SignOptions();
CertificateHolder certHolder = CertificateHolder.create("pathToCert.pfx", "certPassword");
DigitalSignatureUtil.sign("pathToSrcFile.docx", "pathToDstFile.docx", certHolder, signOptions);

C3 - signing using special provider Id:

SignOptions signOptions = new SignOptions();
CertificateHolder certHolder = CertificateHolder.create("pathToCert.pfx", "certPassword");
DigitalSignatureUtil.sign("pathToSrcFile.docx", "pathToDstFile.docx", certHolder, signOptions);		

Exposed Table.HorizontalAlignment Property

Related issue: WORDSNET-15817

Added new public read-only properties to the Table class.

// Gets table relative horizontal alignment. The value of the property is HorizontalAlignment integer constant.
public int getRelativeHorizontalAlignment()

// Gets table relative vertical alignment. The value of the property is VerticalAlignment integer constant.
public int getRelativeVerticalAlignment()


// It is necessary to use the appropriate properties,

// depending on the floating table or not.

// It is necessary to use the appropriate properties,

// depending on the floating table or not.
if (table.getTextWrapping() == TextWrapping.AROUND)

Prevent Embedding Fonts while Saving into HTML Fixed Format.

Related issue: WORDSNET-15880

We have introduced HtmlFixedSaveOptions.UseTargetMachineFonts property.

/// <summary>
/// Flag indicates whether fonts from target machine must be used to display the document.
/// If this flag is set to true, <see cref="FontFormat"/> and <see cref="ExportEmbeddedFonts"/> properties do not have effect,
/// also <see cref="ResourceSavingCallback"/> is not fired for fonts.
/// Default is false.
/// </summary>
public boolean getUseTargetMachineFonts()
public void setUseTargetMachineFonts(boolean value)
