Aspose.Words for C++ 20.9 Release Notes

This page contains release notes for Aspose.Words for C++ 20.9

Major Features

Starting from this release, we are beginning to publish the Linux version of Aspose.Words for C++. The minimum required version of compilers are the following:

GCC 6.3 or higher
Clang 3.9.1 or higher

Right now, we support only the x86_x64 platform, but we can add other architectures to the next releases on request.

It is the first version for Linux, so there may be artifacts and differences in behavior from both the Windows version of Aspose.Words for C++ and Aspose.Words for .NET. We continue to work on improving the product and adding features from .NET

We have added the following features from Aspose.Words for .NET on this regular monthly release:

VbaReferenceCollection and related types are exposed publicly.
Implemented rendering of metafiles with EMF+ containers.
The FormField font formatting API was extended.

Limitations and API Differences

Aspose.Words for C++ has some differences as compared to its equivalent .NET version of the API. This section contains information about all such functionality that is not available in the current release. The missing features will be added in future releases.

The current release does not support the Metered license.
The current release does not support LINQ and Reporting features.
The current release does not support OpenGL 3D Shapes rendering.
The current release does not support advanced typography based on the HarfBuzz shaper.
The current release does not support loading PDF documents.
The current release has limited support for database features - C++ does not have a common API for DB like .NET System.Data.
The current release supports Microsoft Visual C++ version 2017 or higher and only for the x64 platform.
The current release supports GCC 6.3 or higher and Clang 3.9.1 or higher on Linux and only for the x86_x64 platform.

Public API and Backward Incompatible Changes

This section lists public API changes that were introduced in Aspose.Words 20.9. 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 the existing behavior is especially important and is documented here.

Changed the behavior of the FormField.Font property

Related issue: WORDSNET-522 Changed the behavior of the ‘FormField.Font’ property. It is currently allowed to apply font formatting to the FormField as a whole. When new Font properties are set, they take effect for the entire FormField, including the field value.

Use Case. Explains how to apply font formatting to the FormField as a whole:

    Document doc = new Document("in.doc");
    doc.Range.FormFields[0].Font.Size = 20;
    doc.Range.FormFields[0].Font.Color = Color.Red;
    doc.Save("out.doc");

Deprecated find replace algorithm returned for compatibility reason

Related issue: WORDSNET-21018 The following member has been added to FindReplaceOptions class

    /// <summary>
    /// Gets or sets a boolean value indicating that old find/replace algorithm is used.
    /// </summary>
    /// <remarks>
    /// Use this flag if you need exactly the same behavior as before advanced find/replace feature was introduced.
    /// Note that old algorithm does not support advanced features such as replace with breaks, apply formatting and so on.
    /// </remarks>
    public bool LegacyMode { get; set; }

Related issue: WORDSNET-13678

Implemented a new VbaReferenceCollection class:

/// <summary>
/// Represents a collection of <see cref="VbaReference"/> objects.
/// </summary>
public sealed class VbaReferenceCollection : IEnumerable<VbaReference>
{
	/// <summary>
	/// Removes the first occurrence of a specified VbaReference item from the collection. 
	/// </summary>
	public void Remove(VbaReference item)

	/// <summary>
	/// Removes the VbaReference element at the specified index of the collection. 
	/// </summary>
	public void RemoveAt(int index)

	/// <summary>
	/// Returns the number of VBA references in the collection.
	/// </summary>
	public int Count
}

Implemented a new VbaReference class:

/// <summary>
/// Implements a reference to an Automation type library or VBA project.
/// </summary>
public abstract class VbaReference
{
	/// <summary>
	/// Gets <see cref="VbaReferenceType"/> object that indicates the type of reference that a VbaReference object represents.
	/// </summary>
	public abstract VbaReferenceType Type { get; }

	/// <summary>
	/// Gets a string value containing the identifier of an Automation type library.
	/// </summary>
	/// <remarks>
	/// Depending on reference type, the value of this property can be:
	/// <list type="bullet">
	/// <item>a LibidReference specified at 2.1.1.8 LibidReference of [MS-OVBA]:
	/// >
	/// <item>a ProjectReference specified at 2.1.1.12 ProjectReference of [MS-OVBA]:
	/// >
	/// </list>
	/// </remarks>
	public abstract string LibId { get; }
}

Implemented a new public enum VbaReferenceType:

/// <summary>
/// Allows to specify the type of a <see cref="VbaReference"/> object.
/// </summary>
public enum VbaReferenceType

Added a new public property into VbaProject class:

/// <summary>
/// Gets a collection of VBA project references.
/// </summary>
public VbaReferenceCollection References

Use Case. Explains how to remove some reference from the collection of references of VbaProject:

public void Main()
{
    Document doc = new Document("test.doc");
 
    // Find and remove the reference with some LibId path.
    const string brokenPath = "brokenPath.dll";
    VbaReferenceCollection references = doc.VbaProject.References;
    for (int i = references.Count - 1; i >= 0; i--)
    {
        VbaReference reference = doc.VbaProject.References[i];
        string path = GetLibIdPath(reference);
        if (path == brokenPath)
            references.RemoveAt(i);
    }
 
    doc.Save("NoBrokenRef.doc"); 
}
 
/// <summary>
/// Returns string representing LibId path of a specified reference. 
/// </summary>
private static string GetLibIdPath(VbaReference reference)
{
    switch (reference.Type)
    {
        case VbaReferenceType.Registered:
        case VbaReferenceType.Original:
        case VbaReferenceType.Control:
            return GetLibIdReferencePath(reference.LibId);
        case VbaReferenceType.Project:
            return GetLibIdProjectPath(reference.LibId);
        default:
            throw new ArgumentOutOfRangeException();
    }
}
 
/// <summary>
/// Returns path from a specified identifier of an Automation type library.
/// </summary>
/// <remarks>
/// Please see details for the syntax at [MS-OVBA], 2.1.1.8 LibidReference. 
/// </remarks>
private static string GetLibIdReferencePath(string libIdReference)
{
    if (libIdReference != null)
    {
        string[] refParts = libIdReference.Split('#');
        if (refParts.Length > 3)
            return refParts[3];
    }
 
    return "";
}

/// <summary>
/// Returns path from a specified identifier of an Automation type library.
/// </summary>
/// <remarks>
/// Please see details for the syntax at [MS-OVBA], 2.1.1.12 ProjectReference. 
/// </remarks>
private static string GetLibIdProjectPath(string libIdProject)
{
    return (libIdProject != null) ? libIdProject.Substring(3) : "";
}
