What’s new in this release?

The long awaited version of Aspose.Cells for Java 7.7.1 has been released. This new release supports reading large Excel files with LightCells API. This is a useful feature. Sometimes you need to read data from a huge Microsoft Excel workbook with millions of records and you are always worried about the performance. You want it to take less time and memory to process big files. The LightCells API is useful in that scenario: to read huge Excel spreadsheets, it uses less memory, so you get better performance and efficiency. The sample code given on the blog page reads a big file and retrieves the total number of cells, a count of strings and a count of formulas for each worksheet in the workbook. Another valuable feature is to find the cells with some particular style or formatting. Aspose.Cells supports finding all cells that have a common style or formatting. Aspose.Cells provides the FindOptions.setStyle() method which you can use to specify the style to search cells for. You can now create transparent images of Microsoft Excel worksheet. Sometimes, you need to generate an image of your worksheet as a transparent image. For example, you might want to apply transparency to all the cells which have no fill color. We have added support to parse/ read ActiveX controls in the template files. We have also added a number of enhancements in the new release. In this version, we have refactored the PivotTables module. We’ve made tremendous enhancements and fixed several issues. We have improved the chart to image and sheet to image modules. In this release, we have fixed the issues with manipulating charts and shapes. Several other important issues have also been addressed. For example, issues to do with rendering Microsoft Excel file formats, rendering images from Excel worksheets, rendering shapes and controls data and exporting Excel workbooks to PDF format have been resolved.
