We are pleased to announce the new release of Aspose.Cells for .NET 8.9.2. This release includes several new features and other enhancements with critical bug fixes. Aspose.Cells API has exposed a number of new classes as well as an enumeration to configure font sources for rendering spreadsheets to image formats and PDF. Most important class is the FontConfigs which has many useful factory methods to either set the font sources or set the font substitution along with some inspection APIs to retrieve the list of specified font sources as well as font substitutions. Aspose.Cells APIs search the operating system?s default font directory for the required fonts. In case the required fonts are not available in the system?s font directory then the APIs search through the custom (user defined) directories. It also provides the ability to set user defined font substitutions for rendering purposes. This mechanism is helpful when a required font is not available on the machine where conversion has to take place. You can provide a list of font names as alternative to the originally required font. In order to achieve this, the APIs have exposed a new method which accepts 2 parameters. The first parameter is of type string, which should be the name of font which needs to be substituted. The second parameter is an array of type string. Developers can provide a list of font names as substitution to original font (specified in the first parameter). The Aspose.Cells APIs has also provided means to gather information on what sources and substitutions have been set. Aspose.Cells for .NET API has exposed the Boolean type property along with the an overload of Cells.CopyRows method in order to facilitate the copy rows operation when rows to be copied also contains a chart and its data source. You can make use of these new APIs to point the chart?s data source to the source or destination worksheets. This release allows to get/set the IFilePathProvider for exporting worksheets to separate HTML files. These new APIs are helpful in scenarios where hyperlinks in one worksheet points to a location in another worksheet, where application requirement is to render each worksheet to separate HTML file. Implementing the IFilePathProvider allows to keep the aforementioned hyperlinks intact regardless of the fact that they are pointing to a location in a separate resultant HTML file. It has made a few changes to the publicly exposed APIs in order to keep the API usage simple. This release has includes some important fixes and enhancements. such as enter Cell Data of GridWeb Worksheet in Percentage Format, enhanced HTML rendering engine, Improved PDF rendering engine for charts, shapes as well as style/formatting including cell?s text alignment and Tweaked Aspose.Cells? formula calculation engine to match the results with Excel application. It has handled a few exceptions regarding reading and writing Excel and HTML file formats. In this release, several important issues have been addressed. For example, issues around reading and writing Microsoft Excel file formats, rendering images from Excel worksheets, rendering images files from charts and exporting Excel workbooks to PDF format have been resolved.
