Aggiornamenti in V26.6

Funzionalità

• Integrated OCR for PDF Text Recognition
  • Introduced integrated OCR support for extracting plain text from PDF pages that need optical character recognition. Added the Aspose.Pdf.Ocr namespace with OcrTextAbsorber, OcrTextRecognitionOptions, and OcrLanguage.
  • The OCR absorber follows the familiar Aspose.PDF visitor pattern. You can recognize text from a single Page, from a whole Document, or by passing the absorber to Page.Accept or PageCollection.Accept. Recognition options allow you to configure the language, rendering resolution, and page separator used when text is recognized from multiple pages. By default, OCR uses OcrLanguage.English, 300 DPI, and a double line break between recognized page texts.
• Signing with Certificate and TSA
  • Improved certificate-based signing workflows that use a timestamp authority (TSA). This helps you to create signatures with timestamp settings when a signing certificate and TSA server are used together.
  • You can embed a timestamp in the digital signature that corresponds to the certificate of your choice. The timestamp settings are assigned to the signature object before calling PdfFileSignature.Sign.
