V25.5 での更新項目

機能

• Added the ability to get System.Security.Cryptography.X509Certificates.X509Certificate2 for PdfFileSignature class. You can use the PdfFileSignature.TryExtractCertificate method to extract a certificate stream or a X509Certificate2 object.
• Added functionality to create ordered lists. This technique creates lists of related items using list elements appropriate for their purposes. PDF files containing lists are normally created or repaired using a tool for authoring PDF. When markup is used to visually format items as a list but does not indicate the list relationship, users may have difficulty navigating the information. The PDF specification defines list structure in section 14.8.4.3.3 (List Elements). The structure types for lists in PDF documents are:
  • L - the List tag, which contains one or more LI tags.
  • LI - the List Item tag. List item tags can contain Lbl and LBody tags.
  • Lbl - the list item label. Contains distinguishing information such as a item number or bullet character.
  • LBody - the list item body. Contains list item content, or in the case of a nested list, it may contain additional List tag trees.
• Added CreateListLIElement, CreateListLblElement, and CreateListLBodyElement methods to create corresponding logical structure elements.
• You can now use an external certificate containing the public key that corresponds to the private key used to sign the document to verify the signature.
• In some cases (e.g, in the case of a static XFA form), conversion to AcroForm may suffer from the disabled NeedsRendering flag that signals that the form isn't dynamically rendered. To convert such forms and remove the XFA form, it's recommended to use the IgnoreNeedsRendering property to count the document as dynamically rendered and to calculate element conversion properly.
• When converting PDF to XPS, you may find that the fonts embedded in the PDF are not in a format suitable for XPS. At the same time, if a font with such a name is not found in the system, this leads to corrupted text. While you can't fix an embedded font during conversion without access to the original font file, you can now replace it. Also, avoiding the use of embedded TrueType fonts can reduce conversion time.
• Hyperlinks are now preserved when converting from PDF to XLSX.
