What's new in Aspose.Words for .NET
This page describes the most interesting new Aspose.Words features introduced in recent releases.
Aspose.Words for .NET 20.9, 20.10
Aspose.Words 20.9 expands control over Macros, as well as improves the quality of converting from PDF to Word document formats.
Aspose.Words 20.10 introduces a new load format and new options for working with rendering features.
The API is enhanced for more flexible and convenient development.
Support for loading CHM documents has been added. CHM or Microsoft Compiled HTML Help is a proprietary format consisting of a collection of pages, index, and other navigation tools. Starting from version 20.10, it is possible to load CHM documents into Aspose.Words document model and convert them to any supported formats.
Obtaining a Document with Specified Pages
A new method ExtractPages has been added to the Document class. This method returns a new document consisting of nodes located in the current document within a specified page range. The resulting document should look like one in Microsoft Word, as if we were performing “Print specific pages” – all formatting and layout will be preserved.
Export of Specific Pages to Fixed Page Formats
A new public API has been implemented for exporting specific pages to fixed page formats. Previously, you could specify only one continuous range for rendering, but now you can specify a complex set of pages based on different page ranges or individual pages in any order. This provides a flexible way to combine pages into final documents in fixed page formats.
The First Version of SmartArt Cold Rendering
The first version of SmartArt Cold Rendering has been released. Microsoft Word generates and saves the pre-rendered drawing along with SmartArt objects. In most cases, the pre-rendered drawing is rendered well by Aspose.Words and no additional actions required. However, if the document is saved by other applications, the pre-rendered SmartArt drawing may be missing or incorrect. In this case, the SmartArt object itself should be laid-out and rendered. We call this process the SmartArt Cold Rendering, and it is now available in Aspose.Words.
PDF import is now faster and more accurate. Footnotes support has been implemented and integrated to the latest version.
The VbaReferenceCollection class and related types are exposed publicly. Now you have more control over Macros, for example, removing a Template and all its references from the code without using Microsoft Word.

Aspose.Words for .NET 20.5, 20.6, 20.7, 20.8
Aspose.Words 20.5 introduces performance improvements and enhanced document display capabilities.
Aspose.Words 20.6 expands formatting options, makes saving to Markdown more convenient, and improves SmartArt Cold Rendering.
Aspose.Words 20.7 introduces structured document tags, expands mail merge functionality and document display capabilities.
Aspose.Words 20.8 expands the capabilities of working with images in various supported document formats and improves font substitution rules to ensure a high level of rendering.
The API is improved for more flexible and convenient development.
As you know, .NET 5 is going to be released soon, as the next step forward with .NET Core. It will be useful for you to know that .NET 5 Preview 4 is already available for testing. We have made sure and tested that Aspose.Words works fine with .NET 5 Preview 4.
Performance and Data Compression
A new public property CompressionLevel has been added for OOXML documents. Using this property, you can control the compression level when saving a document. For example, you can select the SuperFast compression level that is used in Microsoft Word. Or leave the Normal compression level used in Aspose.Words by default.
A new public class MarkdownSaveOptions has been added to work with advanced options when saving a document to Markdown format. In addition to overloaded and inherited properties, the TableContentAlignment property has been added to this class to control the alignment of content in tables when converting a document to Markdown format.
Layout Callback to Interrupt the Layout Building
The long-awaited layout callback has been implemented and made available to the public. The IPageLayoutCallback interface allows your application to interrupt the process of layout building for the entire document and render only the part already built.
Formatting options have been extended:
- A new public property EmphasisMark has been added to manage the emphasis mark – an additional character that is rendered above or below the main character glyph. Now you can control its behavior using the EmphasisMark option.
- A new public property IgnoreHeaderFooter has been added to manage the formatting of headers/footers content. Using this option, you can specify whether to ignore the source formatting of the headers/footers content if the KeepSourceFormatting formatting mode is used.
Advanced Control over Revision Options
The RevisionOptions class has been extended with new properties. Now you have more control over the revision options, such as revision bars position represented by the RevisionBarsPosition property and measurement units represented by the MeasurementUnit property.
Font Substitution Rules
A new font substitution rule has been added through the FontNameSubstitutionRule class. This rule tries to process font name suffixes in the same way as Microsoft Word does.
Watermarks in Documents
A new helper class Watermark has been introduced to work with a watermark inside a document. This class simplifies the way you add or remove a watermark in a document – now you can do it with just one line of code! You can easily create a watermark from text or an image, as well as control its display settings.
Improving SmartArt Rendering
SmartArt Cold Rendering has become even better – the processing of hyperlinks in the SmartArt data model has been implemented and the preliminary processing of the chart drawing has been improved.
- A new ability to show or hide grammatical and spelling errors has been provided. Using the ShowGrammaticalErrors and ShowSpellingErrors properties, you can easily control the way grammatical and spelling errors are displayed in your document.
- Two new nodes have been introduced to handle multi-section structured document tags. These structured document tags are now supported upon import/export.
- A new public property RetainFirstSectionStart has been added to get or set a value that indicates whether the SectionStart of the first document section and its copies for subsequent data source rows are retained during mail merge or updated according to Microsoft Word behavior.
- Markdown ‘Inline Images’ feature has been implemented to make our Markdown support even better.
- The SkipPdfImages flag has been added to the PdfLoadOptions class to indicate whether images must be skipped when loading a PDF document.
- Support for SVG images embedded using data URLs upon HTML import has been implemented.

Aspose.Words for .NET 20.3, 20.4
Aspose.Words 20.3 introduces support of separate DLLs for Xamarin.Android, Xamarin.Mac and Xamarin.iOS, as well as huge performance and memory improvements.
Aspose.Words 20.4 introduces support for .NET 4.6.1, 3D Effects Rendering through the OpenGL feature in two modes – basic or advanced.
The API is enhanced for more flexible and convenient development.
Xamarin Support Changes
Starting with Aspose.Words 20.3, Xamarin support has changed. In earlier versions, we provided separate DLLs for Xamarin.Android, Xamarin.Mac and Xamarin.iOS. Now Xamarin developers can use Aspose.Words for .NET Standard in all mentioned platforms. According to the .NET Standard documentation, Aspose.Words for .NET Standard 2.0 can be used with Xamarin.iOS 10.14 or newer, Xamarin.Mac 3.8 or newer, and with Xamarin.Android 8.0 or newer.
New Platform Support: .NET 4.6.1
Starting from 20.4 version, Aspose.Words has a dedicated release for .NET 4.6.1 framework.
Performance and Memory Improvements
We released Aspose.Words for .NET and, as always, Aspose.Words for Java almost at the same time. And we are pleased to present the huge performance and memory improvements in Aspose.Words for Java 20.3 due to the NodeCollectionEnumerator algorithm optimization, removing the Ref<T> objects creation from nested cycles, and Blank documents loading optimization using arraycopy for small arrays.
3D Effects Rendering Support
The first version of 3D Effects Rendering through the OpenGL feature has been released. You can select one of two rendering modes for 3D shape effects rendering – “Basic mode” or “Advanced mode”:
- Basic mode – the default lightweight and stable rendering, based on the internal engine, but without advanced effects.
- Advanced mode – rendering of an extended list of special effects, including advanced 3D effects, such as bevels, lighting, and materials, via OpenGL. We position this feature as experimental since it is under development, and there is a number of limitations for advanced mode.
More Chart Customization
The API for chart data labels and series has expanded. Now you have more control over data labels, series, and their formatting.
New Image Fidelity Options for PDF Format
The InterpolateImages interpolation property indicates that a PDF Reader (for example, Acrobat Reader), should smooth the image to make it look more “attractive”. For different PDF Readers, this property can work in different ways: some readers may choose to not implement this PDF feature, others use any specific implementation of interpolation that they wish. Using the InterpolateImages property is relevant if the resolution of a source image is significantly lower than the resolution of the output device.
Search and Compare
Search and compare options are extended:
- The functionality of the FindReplaceOptions class becomes more flexible to serve your needs. It is now possible to ignore text inside revisions and fields. You can also enable the use of substitutions in the replacement pattern via the UseSubstitutions property – this makes easy to use part or whole match when replacing.
- The Granularity option, allowing the customer to specify comparison granularity, has been added. This feature allows you to specify the exact granularity of changes to track when comparing two documents.
- A new public property UpdateLastPrintedProperty has been added. Using this property, you can control when to update LastPrintedProperty, for example, before printing.
- The ability to change Asian paragraph spacing and indents through the public API has been added. This is the next step of Chinese language-specific Paragraph formatting improvement.
