Public API and Backward Incompatible Changes

This section lists public API changes that were introduced in Aspose.Words 17.4. 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 an Interface to Flexibly Format Field Result

WORDSNET-14944 has been resolved.

We have added an interface allowing to implement a custom formatting of field’s result. The original request was about addiing a feature to remove spaces between sign and digits during mail merge. However, we decided to implement a more generic and flexible solution because our API is already overwhelmed with different specific properties.

DocumentBuilder builder = new DocumentBuilder();
Document document = builder.Document;
Field field = builder.InsertField("=-1234567.89 \\# \"### ### ###.000\"", null);
document.FieldOptions.ResultFormatter = new FieldResultFormatter("[{0}]", null);
field.Update();
Assert.AreEqual("[-1234567.89]", field.Result);
private class FieldResultFormatter : IFieldResultFormatter
{
    public FieldResultFormatter(string numberFormat, string dateFormat)
    {
        mNumberFormat = numberFormat;
        mDateFormat = dateFormat;
    }
    public FieldResultFormatter()
        : this(null, null)
    {
    }
    public string FormatNumber(double value, string format)
    {
        mNumberFormatInvocations.Add(new object[] { value, format });
        return string.IsNullOrEmpty(mNumberFormat)
            ? null
            : string.Format(mNumberFormat, value);
    }
    public string FormatDate(DateTime value, string format, CalendarType calendarType)
    {
        mDateFormatInvocations.Add(new object[] { value, format, calendarType });
        return string.IsNullOrEmpty(mDateFormat)
            ? null
            : string.Format(mDateFormat, value);
    }
    public string FormatNumber(double value, string format, string formattedValue)
    {
        throw new NotImplementedException();
    }
    public string FormatDate(DateTime value, string format, CalendarType calendarType, string formattedValue)
    {
        throw new NotImplementedException();
    }
    private readonly string mNumberFormat;
    private readonly string mDateFormat;
    private readonly ArrayList mNumberFormatInvocations = new ArrayList();
    private readonly ArrayList mDateFormatInvocations = new ArrayList();
}

Added Feature to Set Horizontal and Vertical Resolution of Output Image

Previously it was one property Resolution that set both vertical and horizontal resolution to the same values. Now new public properties HorizontalResolution and VerticalResolution are added into the ImageSaveOptions class:

/// <summary>
/// Gets or sets the horizontal resolution for the generated images, in dots per inch.
/// </summary>
/// <remarks>
/// <para>This property has effect only when saving to raster image formats.</para>
/// <p>The default value is 96.</p>
/// </remarks>
public float getHorizontalResolution()
public void  setgetHorizontalResolution(float value)
/// <summary>
/// Gets or sets the vertical resolution for the generated images, in dots per inch.
/// </summary>
/// <remarks>
/// <para>This property has effect only when saving to raster image formats.</para>
/// <p>The default value is 96.</p>
/// </remarks>
public float getVerticalResolution()
public void  getVerticalResolution(float value)

Please note, that Resolution property became write-only:

/// <summary>
/// Sets both horizontal and vertical resolution for the generated images, in dots per inch.
/// </summary>
/// <remarks>
/// <para>This property has effect only when saving to raster image formats.</para>
/// </remarks>
public void setResolution(float value)
