GroupDocs.Editor for .NET 23.4 Release Notes
GroupDocs.Editor for .NET version 23.4 is a new significant update that contains several new features, plenty of useful improvements and a lot of bugfixes in different modules of the GroupDocs.Editor, primarily in HTML/CSS sub-system, e-Book module, and WordProcessing module.
New features and improvements
Ability to generate a preview of selected worksheet of a loaded spreadsheet in SVG format
Starting from the version 23.4 the GroupDocs.Editor for .NET is able to generate an SVG preview of arbitrary worksheet within spreadsheet. In order to do this need to load a desired spreadsheet document inside the Editor class, invoke the GetDocumentInfo method, and then in the obtained GroupDocs.Editor.Metadata.SpreadsheetDocumentInfo struct call the GeneratePreview(int worksheetIndex) method.
A separate article “Generating worksheets (tabs) preview for spreadsheet” explains this new feature in detail.
New e-Book save options
In previous versions there were two different classes for save options for the e-Book formats family: EpubSaveOptions and Azw3SaveOptions. In version 23.4 these classes are deleted and replaced with single common EbookSaveOptions class. Article “How to edit e-Book file” explains this change in detail.
Support of export into Mobi format
Before the version 23.4 was released, the Mobi format was supported only on import, so it was possible to load and edit a Mobi document, but not to save the edited document in Mobi format. Starting from the version 23.4 this is possible. Article “How to edit Mobi file “ explains this in detail.
Greatly improved HTML parser
In the version 23.4 the HTML parser was significantly improved. Now it is able to correctly process invalid, incorrect and distorted markup. In particular, the next distortions are supported:
- Flow elements nested inside phrasing elements, for example,
PinsidePorDIVinsideSPAN. - Prohibited elements and nodes inside TABLE element, for example, prohibited
PinsideTABLEorDIVinsideTRwill be pushed upward. SELECTis generated and applied as a parent for the orphanOPTION/OPTGROUPelements, becauseOPTION/OPTGROUPmust be direct children of theSELECT.COLGROUPis generated and applied as a parent for theCOL.- Incorrectly nested lists are properly processed.
- Better parsing of HTML attributes
- And many more
New method for obtaining an HTML markup
Now the EditableDocument class contains a new public method EditableDocument.GetContent, which allows to obtains the HTML markup of the opened document and write it to the specified stream with specified text encoding.
