Public API and Backward Incompatible Changes

This section lists public API changes that were introduced in Aspose.Words 20.8. 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.

Added new FontNameSubstitutionRule

Related issue: WORDSNET-20199 Added new font substitution rule for font name processing. It will be checked at the step 4 before item a. at Font Availability and Substitution. If this substitution rule will take place the warning with text “Font ‘’ has not been found. Using ‘’ font instead. Reason: font name substitution.” will be issued.

/// <summary>
 /// Font substitution rule for processing font name.
 /// </summary>
 /// <remarks>
 /// According to this rule Aspose.Words tries to process the font name to get the substitution. Particularly
 /// Aspose.Words tries to removes suffixes with '-' and ',' separators like it does the MS Word. 
 /// </remarks>
public class FontNameSubstitutionRule : FontSubstitutionRule
public class FontSubstitutionSettings
    /// <summary>
    /// Settings related to font name substitution rule.
    /// </summary>
    public FontNameSubstitutionRule FontNameSubstitution { get; }

Added new option to the PdfLoadOptions class

Related issue: WORDSNET-20779 Added flag indicating whether images must be skipped while loading PDF document.

/// <summary>
 /// Gets or sets the flag indicating whether images must be skipped while loading PDF document. Default is False.
 /// </summary>
public bool SkipPdfImages
    get { return mSkipPdfImages; }
    set { mSkipPdfImages = value; }

Use Case: Explains how to use SkipPdfImages flag.

fLoadOptions options = new PdfLoadOptions();
 options.SkipPdfImages = true;
 Document doc = new Document("in.pdf", options);

Removed obsolete property FindReplaceOptions.PreserveMetaCharacters

Related issue: WORDSNET-20266 Removed obsolete property from FindReplaceOptions class.

/ <summary>
 /// True indicates that meta-characters beginning with "&amp;" are preserved.
 /// Default value is false.
 /// </summary>
 [Obsolete("This property is obsolete. Please use &amp; character to escape meta-characters instead.")]
 public bool PreserveMetaCharacters

Use Case: Explains how to replace text ignoring meta-characters.

cumentBuilder builder = new DocumentBuilder();
 doc.Range.Replace("&&", " & ");
 // The output is: text & plain\f
