機能

• Automatic creation of tags has been added to the PDF to PDF/A conversion. A PDF document may include logical structure tags to enhance accessibility and organization. These tags structure the document's content by dividing it into logical parts, such as sections, paragraphs, and more. When a document is converted to PDF/A, Aspose.PDF can automatically generate a basic logical structure markup. Users can then manually refine this structure, adding further insights about the document's content. To generate a logical document structure, create an instance of the Aspose.Pdf.AutoTaggingSettings class, set its AutoTaggingSettings.EnableAutoTagging to true, and assign it to the PdfFormatConversionOptions.AutoTaggingSettings property.
• Optical character recognition (OCR) is the electronic conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, etc. Starting from this release, OCR capability has been added to the PDF AI Copilot.
• Sometimes, it is necessary to print multiple related documents together as a single print job. This ensures that these documents do not get interspersed with output from other users, especially with remote network printers. Aspose.PDF now supports printing any number of documents in a single print job with shared printer settings via the static PrintDocuments methods of the PdfViewer class. The documents to be printed can be provided as file paths, document streams, or Document objects.
• You can now create your own security handler by applying the desired encryption algorithm. The Adobe Acrobat will not be able to open such a file, but you can work with it using Aspose.PDF.
• Added a Setter for annotation creation date.
• Added PDF/A-4 support for the PdfAConverter plugin.
• Added the ability to check certificates for revocation with support for certificate chains.
