What is new in this release?

The long awaited version of Aspose.Cells for Java 8.7.0 has been released. Aspose.Cells APIs have provided an enhancement for the PDF rendering engine in order to reduce the resultant PDF file size. It has exposed a new property along with an enumeration by the name PdfOptimizationType in order to facilitate the application developers to control the resultant PDF file size to some extent. The piece of code on the blog announcement demonstrates the usage of PdfSaveOptions.OptimizationType property to minimize the resultant PDF file size while exporting spreadsheets to PDF format. It has also exposed the boolean type property in order to mimic the Excel’s feature of re-sizing data label shapes to fit the text. Please note, Excel application provides the Resize shape to fit text option for chart’s data labels to increase the size of the shape so that the text fits inside of it. This option can be accessed on Excel interface by selecting any of the data labels on the chart. Right click and select Format DataLabels menu. Aspose.Cells APIs have enhanced the Protection class by introducing some useful properties & methods. Two of the most worth mentioning enhancements are as follow. It is possible to protect the workbooks and worksheets separately. For instance, a spreadsheet may contain one or more worksheets that are password protected, however, the spreadsheet itself may or may not be protected. Aspose.Cells API for Java has provided a field to detect if a worksheet is password protected. Boolean type field returns true if Worksheet is password protected and false if not. It has exposed the Protection.verifyPassword method which allows to specify a password as an instance of String and verifies if same password has been used to protect the worksheet. The Protection.verifyPassword method returns true if the specified password matches with the password used to protect the given Worksheet, false if specified password does not match. Aspose.Cells for Java has provided support to identify & parse the formulas while loading CSV/TXT files having delimited plain data. Newly exposed TxtLoadOptions.HasFormula property when set to true directs the API to parse the formulas from the input delimited file and set them to relevant cells without requiring any additional processing. This release of the API has has exposed the ColorScale.Is3ColorScale property that can be used to create 2-Color Scale conditional format. The said property is of type boolean with default value of true which means that the conditional format will be of 3-Color Scale by default. However, switching the ColorScale.Is3ColorScale property to false will generate a 2-Color Scale conditional format. This release includes several enhanced features and bug fixes as listed below
