Public API and Backward Incompatible Changes

This section lists public API changes that were introduced in Aspose.Words 20.12. 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 regression and modifies existing behavior is especially important and is documented here.

Added a new public properties Document.SpellingChecked and Document.GrammarChecked

Related issue: WORDSNET-21120

Added a new public property SaveOptions.AllowEmbeddingPostScriptFonts:

/// <summary>
/// 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<.
/// </summary>
/// <remarks>
/// <para>Note, Word does not embed PostScript fonts, but can open documents with embedded fonts of this type.</para>
/// <para>This option only works when <see cref="FontInfoCollection.EmbedTrueTypeFonts"/> of the
/// <see cref="DocumentBase.FontInfos"/> property is set to true.</para>
/// </remarks>
public bool AllowEmbeddingPostScriptFonts { get; set; }

Use Case:

const string testDir = "\\TestDir\\";
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
// Create some content that will use PostScript font.
builder.Font.Name = "PostScriptFont";
builder.Writeln("Some text with PostScript font.");
// Load the font with PostScript to use in the document.
FontSourceBase otf = new MemoryFontSource(File.ReadAllBytes(testDir + "PostScriptFont.otf"));
FontSourceBase[] sources = new FontSourceBase[] {otf};
doc.FontSettings = new FontSettings();
// Embed TrueType fonts.
doc.FontInfos.EmbedTrueTypeFonts = true;
// Allow embedding PostScript fonts while embedding TrueType fonts.
SaveOptions saveOptions = SaveOptions.CreateSaveOptions(SaveFormat.Docx);
saveOptions.AllowEmbeddingPostScriptFonts = true;
// Save document with embedded PostScript font.
doc.Save(testDir + "out.docx", saveOptions);

Changed DocumentBuilder.InsertImage behavior when insert SVG images

We changed DocumentBuilder.InsertImage behavior when insert SVG. Earlier Aspose.Words inserted SVG as EMF metafile to keep the inserted image in vector representation. Now AW inserts SVG as PNG with svgBlip extension that contain the original SVG image, just like MS Word does.

Use Case 1:

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

SVG image is inserted into the document as PNG with svgBlip extension that contains the original vector SVG image representation.

Use Case 2 - Document is saved in old MS Word format:

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

SVG image is saved to output document as PNG, just like MS Word does.

Use Case 3 - Document is optimized for old versions of MS Word using OptimizeFor method:

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

SVG is inserted into the document as EMF metafile to keep the image in vector representation (old Aspose.Word behavior).

Changed version of MS Word during import Html

Related issue: WORDSNET-20364

Previously, the LoadOptions.MswVersion property had no effect when loading documents from HTML and HTML-based formats (for example, MHTML). All documents were loaded as if no MswVersion were specified. This has been changed and now the HTML reader may load documents differently depending on the value of MswVersion. Since the default value of MswVersion is MsWordVersion.Word2019, by default HTML documents are loaded as if they are opened by MS Word 2019.

Customer may change this behavior by specifying the required version of MS Word in LoadOptions. For example:

LoadOptions loadOptions = new LoadOptions();
loadOptions.MswVersion = Settings.MsWordVersion.Word2010;
Document doc = new Document("in.html", loadOptions);

Implemented condition evaluation extension point

Related issue: WORDSNET-20913

We have implemented extension point for condition evaluation. This allows users to implement custom evaluation for the IF and COMPARE fields.

/// <summary>
/// The comparison expression.
/// </summary>
public sealed class ComparisonExpression
    /// <summary>
    /// Gets left expression.
    /// </summary>
    public string LeftExpression { get; }
    /// <summary>
    /// Gets comparison operator.
    /// </summary>
    public string ComparisonOperator { get; }
    /// <summary>
    /// Gets right expression.
    /// </summary>
    public string RightExpression { get; }

public sealed class ComparisonEvaluationResult
    /// <summary>
    /// Creates comparison evaluation result.
    /// </summary>
    public ComparisonEvaluationResult(bool result)
        // ...
    /// <summary>
    /// Creates failed comparison evaluation result with corresponding error message.
    /// </summary>
    public ComparisonEvaluationResult(string errorMessage)
        // ...
    /// <summary>
    /// Gets comparison evaluation result. 
    /// </summary>
    public bool Result { get; }
    /// <summary>
    /// Gets failed comparison evaluation result error message.
    /// </summary>
    public string ErrorMessage { get; }

/// <summary>
/// When implemented allows to override default comparison expressions evaluation for the <see cref="FieldIf"/> and <see cref="FieldCompare"/> fields.
/// </summary>
/// <seealso cref="FieldOptions.ComparisonExpressionEvaluator"/>
public interface IComparisonExpressionEvaluator
    /// <summary>
    /// Evaluates comparison expression.
    /// </summary>
    /// <remarks>
    /// The implementation should return <b>null</b> to indicate that the default evaluation should be performed.
    /// </remarks>
    ComparisonEvaluationResult Evaluate(Field field, ComparisonExpression expresion);

public sealed class FieldOptions
    /// <summary>
    /// Gets or sets the field comparison expressions evaluator.
    /// </summary>
    /// <seealso cref="IComparisonExpressionEvaluator"/>
    public IComparisonExpressionEvaluator ComparisonExpressionEvaluator { get; set; }

Use Case:

public class ComparisonExpressionEvaluator : IComparisonExpressionEvaluator
    public ComparisonExpressionEvaluator(ComparisonEvaluationResult result)
        mResult = result;
    public ComparisonEvaluationResult Evaluate(Field field, ComparisonExpression expresion)
        return mResult;
    private readonly ComparisonEvaluationResult mResult;

ComparisonEvaluationResult result = new ComparisonEvaluationResult(true);
ComparisonExpressionEvaluator evaluator = new ComparisonExpressionEvaluator(result);
document.FieldOptions.ComparisonExpressionEvaluator = evaluator;

Provided an option to import styles from a dynamically inserted document for LINQ Reporting Engine

Related issue: WORDSNET-20552

The “Inserting Documents Dynamically” section of the engine’s documentation was updated to describe the change.
