GroupDocs.Signature for Java for Java 23.4

What’s new in the GroupDocs.Signature for Java 23.4

Release Highlights

GroupDocs.Signature for Java 23.4 delivers substantial enhancements for better traceability and control in document signing operations. This release introduces new logging capabilities via log level flags, a DataType property for metadata signatures, and performance metrics accessible through the IResult interface. Several platform-specific issues, especially under Linux, have been addressed, improving document preview accuracy and export reliability across Word Processing, Spreadsheet, and PNG image formats.

New Features

• Configurable Logging with LogLevel Enumeration: Introduced LogLevel enumeration to fine-tune logging verbosity. Log levels such as Error, Warning, Info, and Trace can be combined using flags.
• DataType Property in MetadataSignature: New DataType field added to MetadataSignature class to allow semantic typing of metadata values for greater precision during signing and validation.
• Trace Logging for Signature Operations: Trace logs now provide detailed method-level insights during Sign, Update, Delete, Search, and Verify processes for better diagnostics.
• Metrics for Signature Results: IResult interface now includes performance metrics: processing time, total signatures, and document sizes.

Enhancements

• Log Level Flags Support: Enabled the ability to set multiple log levels simultaneously to customize output verbosity via SignatureSettings.
• Process Metrics in All Signature Actions: All result types (SignResult, UpdateResult, DeleteResult, VerificationResult, SearchResult) now implement IResult for real-time analytics.
• Dependency Updates: Referenced libraries and dependencies have been updated for performance and compatibility.

Bug Fixes

• Linux Compatibility - Word Processing Preview Fix: Resolved issues with previewing Word documents in JPG format under Linux environments.
• QRCode Verification - Linux Fix: Corrected unexpected verification results when checking QRCode signatures on Linux systems.
• PFX Certificate Detection Improved: Fixed recognition issues with specific PFX certificate files during signing and validation.
• Accurate PNG Export Restored: Corrected PNG corruption during image exports from document pages.
• Spreadsheet Page Size Issue Fixed: Resolved incorrect page size values when accessing Spreadsheet document metadata.

Public API and Backward Incompatible Changes

• New LogLevel Enumeration Added:

  • Enables control over logging output within SignatureSettings.

• Updated IResult Interface with Performance Metrics:

  • getProcessingTime() – Returns processing time in milliseconds.
  • getTotalSignatures() – Returns total count of processed signatures.
  • getSourceDocumentSize() – Returns size of input document in bytes.
  • getDestinDocumentSize() – Returns size of output document in bytes.

• Classes Now Implementing IResult:

  • SignResult
  • UpdateResult
  • DeleteResult
  • VerificationResult
  • SearchResult
