Aspose.Words for Java 26.6 Release Notes

Major Features

There are 65 improvements and fixes in this regular monthly release. The most notable are:

• License: Updated the Java Metered License Billing Code.
• Printing: Added Windows-specific target framework monickers (net6.0-windows and net8.0-windows) to the NuGet package. This enables the use of Document.Print() and related printing APIs in .NET Core applications running on Windows.
• Document Customization: Added a new method to easily clear custom toolbars and keyboard shortcuts, helping you reset or secure document settings.
• PDF Export: Enabled seamless export of datetime form fields to PDF, ensuring your date and time data transfers accurately.
• PDF Export: Introduced JavaScript trigger support for date/time fields in PDF AcroForms, making your exported forms more interactive and responsive.
• PDF Export: Enhanced hyphenation rendering; if a font lacks an optional hyphen (U+00AD), it now automatically falls back to a visual hyphen while keeping your text fully searchable.
• PDF Export: Improved overall PDF output quality by fully preserving date picker content controls.
• Tables: Improved the handling of repeated table header rows for cleaner, more predictable layouts in multi-page tables.

Added support for datetime form fields export to PDF

Related issue:WORDSNET-28705

Implemented support for exporting date/time fields to PDF AcroForms using JavaScript trigger events. The feature is controlled by the PdfSaveOptions.GenerateFormFieldScripts public option and is disabled by default because JavaScript support is limited in PDF viewers other than Acrobat.

/// <summary>
/// Specifies whether to generate scripts that emulate specific Microsoft Word form field behavior in PDF.
/// Default is <c>false</c>.
/// </summary>
/// <remarks>
/// <para>When this option is enabled, the exporter generates PDF JavaScript actions to emulate Microsoft Word
/// form field behavior, such as date and time form fields with formatting and validation rules.</para>
/// <para>When set to <c>true</c>, supported behavior will be exported as PDF JavaScript actions.
/// When set to <c>false</c>, no form field scripts will be generated.</para>
/// <para>Script execution depends on the PDF viewer. Some PDF viewers might ignore scripts, restrict script execution,
/// or require the user to enable JavaScript.</para>
/// <para>JavaScript actions are prohibited by PDF/A-1, PDF/A-2 and PDF/A-3 compliance.
/// The <c>false</c> value will be used automatically in this case.</para>
/// </remarks>
public bool GenerateFormFieldScripts { get; set; }
