Public API and Backward Incompatible Changes

This section lists public API changes that were introduced in Aspose.Words 16.7.0. 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 Public Methods to the DigitalSignatureUtil Class that Allow to Specify a Password for Decrypting Document before it will be Signed.

WORDSNET-13735 is resolved and we have added following static methods for signing encrypted documents:

Methods sign source file or stream using given certificate holder and writes signed document to destination file/stream.
In the last parameter you can specify a password for decrypting source document. If document is not encrypted this parameter will be ignored.
Also, this is meaningful only if source document has DOCX format.

UC1 (working with file)

UC2 (working with stream)

A Document Page can now be Saved in GIF Format

The document page can now be saved into GIF format just like any other image formats. A new 'Gif' member is added into 'SaveFormat' enum.

Aspose.Words for .Net uses standard GIF codec provided by GDI+. Aspose.Words for Java uses standard GIF codec provided by ImageIO.

Sample code:

Exposed more String and Number Formats for Expression Results in LINQ Reporting Engine

The "Outputting Expression Results" section of the engine's documentation was updated to describe the change.

MsWordVersion Enum Moved to Aspose.Words.Settings

Customers will now have to use 

to work with MsWordVersion.

This however should not be a breaking change as presently CompatibilityOptions.OptimizeFor is the only method that uses MsWordVersion enum and is already a member of Aspose.Words.Settings namespace.

ReplaceAction, IReplacingCallback and ReplacingArgs Moved to Aspose.Words.Replacing

During WORDSNET-1252 implementation we decided to create new namespace Aspose.Words.Replacing and move classes related to find/replace operations to this new namespace.

WORDSNET-1252. Advanced replace methods

Two methods were added to class Range to support advanced find/replace operations.

These methods support breaks in both search pattern and replacement string. Customer needs to use special meta-characters to specify breaks: &p for paragraph break, &b for section break, &m for page break and &l for manual line break.Also new FindReplaceOptions class was introduced to hold all find/replace options. Most notable member of this class is ApplyFont/ApplyParagraphFormat. It allow to specify text/paragraph formatting to be applied to replacement text.

Below are couple examples.

UC1

Demonstrate how breaks support works. In this example we replace certain paragraph breaks with new paragraph breaks + some underline while make it centered. Additionally we replace custom text tag with section break.

UC2

Demonstrates usage of apply formatting and customer callback. In this example we replace numbers with their hexadecimal representations while make them highlighted with color.

Some improvements were made to make replace method to be isolated from changes made by customer in callback.

Deprecated methods

Old Replace methods are left for backward compatibility but marked as obsolete.

We going to remove following methods in this year:

One old method

continues to work with old code and will be switched to new code eventually.

WORDSNET-4285 - SKIPIF field supported

This feature has been requested by a few customers and we have it implemented now. SKIPIF field is now updated during mail merge.

WORDSNET-6205 Added Support for MathML in HTML Export

WORDSNET-6205 is implemented.

Added support for MathML in HTML export.

The following property is added to HtmlSaveOptions class:

The following enum is publicly available:

Sample output for simple OfficeMath equation exported using HtmlOfficeMathOutputMode.Image value:

Sample output for simple OfficeMath equation exported using HtmlOfficeMathOutputMode.MathML value:

Sample output for simple OfficeMath equation exported using HtmlOfficeMathOutputMode.Text value:

WORDSNET-12901 Implemented API for Adding or Removing Embedded Fonts

WORDSNET-12901 is implemented.

Added following properties to FontInfoCollection class:

WORDSNET-13817 Font Substitution Rules Improved

Improvement is made in case when specific font is not installed but is embedded into the document and a substitute for this font is assigned.

Previously font substitute was used in this case. Now embedded font is used.
