We are pleased to announce the new release of Aspose.Cells for Java 8.9.2. This release includes many new features and enhancements along with some critical bug fixes that further improve the overall stability of the API. Aspose.Cells for Java 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. Developers can Set Font Sources and can also Substitute Fonts. It has exposed the Boolean type property to true and passing the object to calculateFormula method directs the Aspose.Cells APIs to calculate the dependent cells recursively when calculating cells which depends on other cells. Aspose.Cells for Java 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. It 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. This release includes some important enhancements, such as HTML rendering engine for shapes such as TextBoxes, Improved PDF rendering engine for charts as well as cell text alignment, Tweaked Aspose.Cells? formula calculation engine to match the results with Excel application and Handled a few exceptions such as IndexOutOfBoundsException, NumberFormatException & OutOfMemoryError for certain scenarios. This release includes several enhanced features and bug fixes as listed below
