What is new in this release?

The long awaited version of Aspose.Cells for Java 8.3.2 has been released. Most worth mentioning feature is the support for Signature Line. Microsoft Excel provides the feature to add Signature Line in Excel spreadsheets by clicking the Insert tab and then selecting the Signature Line from the Text group. This feature allows adding the information about the person whose signatures are required on the document while supplying some key information such as name, designation, email address and so on. Aspose.Cells also provides this feature and has exposed the Picture.setSignatureLine field and SignatureLine class for this purpose. Another worth mentioning feature is the support for Absolute Positioning of the PivotItem. Aspose.Cells for Java 8.3.2 has provided this support by exposing a series of new fields that can be used to specify the position of a PivotItem within a parent node and also in the complete collection. While using Microsoft Excel application, the user can specify the custom Decimal and Thousands separators instead of using the system’s predefined separators for a particular spreadsheet. Same can be achieved using the Aspose.Cells for Java API by using the newly exposed fields. Aspose.Cells for Java 8.3.2 has exposed two new overloads for the SheetRender.toPrinter & same for the WorkbookRender.toPrinter. One of the new an overload accept two integer parameters along with a string parameter for the printer name and prints a range of Worksheet & Workbook pages to the printer. Other overload accepts a string parameter to specify the printing job name along with the printer name. Some Unicode characters cannot be displayed using any specified font but they can be displayed with another font family. One of such Unicode character is the Non-breaking Hyphen (U+2011) and its Unicode number is 8209. This character cannot be displayed with Times New Roman but it can be displayed with other fonts like Arial Unicode MS. When a spreadsheet containing such characters is to rendered on PDF canvas while using a not supporting font family like Times New Roman, the Aspose.Cells API used to change the font of entire word or sentence to another font which could display this character. However, this could be an undesirable behavior for some users and they want only that specific character’s font to be changed instead of changing the font of entire word or sentence. In order to deal with this scenario, the Aspose.Cells for Java 8.3.2 API has exposed the setFontSubstitutionCharGranularity field for the PdfSaveOptions class which should be set to true so that only the font of specific character to be changed to another displayable font whereas the rest of the word or sentence should remain in original font. Charts can be of any type, where a few chart types such as all the variations of the Pie and Doughnut does not have any axis. Previously, it was not possible to retrieve the information about the particular axis of a given chart but with the release of Aspose.Cells for Java 8.3.2, the API has exposed the Chart.hasAxis method to determine if the chart has a particular axis or not.
