Work with XML Maps, Enhanced Protection Module & Digital Signatures for VBA Projects using .NET

We are pleased to announce the new release of Aspose.Cells for .NET 8.7.0. This release contains some useful features and other enhancements along with critical bug fixes. If you are planning to upgrade the Aspose.Cells for .NET API to the latest revision, we would strongly suggest you to check the complete Public API Changes section to know what has been changed in the API so far. Aspose.Cells APIs have provided an enhancement for the PDF rendering engine in order to reduce the resultant PDF file size. It has exposed the PdfSaveOptions.OptimizationType property along with an enumeration by the name PdfOptimizationType in order to facilitate the application developers to control the resultant PDF file size to certain extent. 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. On Size & Properties tab, expand Alignment node to reveal the related properties including the Resize shape to fix text option as highlighted below. Aspose.Cells APIs have enhanced the Protection class by introducing some useful properties & methods. Two of the most worth mentioning enhancements includes Detect if Worksheet is Password Protected and Verify Password Used to Protect the Worksheet. Aspose.Cells for .NET has provided support to identify & parse the formulas while loading CSV/TXT files having delimited plain data. Newly exposed 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 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. The most notable enhancements in this includes, Newly exposed field VbaProject.IsSigned allows to detect if a given VbaProject is digitally signed or not, newly exposed attribute VbaProject.CertRawData allows to export VBA Digital Certificate to streams, newly exposed attribute VbaProject.IsValidSigned allows to determine if the signature is valid, newly exposed method VbaProject.Sign() allows to digitally sign VBA code project and added support for importing XML map inside an instance of Workbook. This release includes several enhanced features and bug fixes as listed below
