Pdftools SDK​

Version 1.5​

Added​

  • You can now apply Mixed Raster Content (MRC) optimization to a PDF document using the Optimize feature of the PDftools SDK. MRC optimization is intended for compressing scanned PDF files that contain large amounts of text.
  • It is now possible to set the values for ThresholdDPI and ReduceColorComplexity when optimizing PDF files. This addition gives you more control over how images in the document are resampled and compressed.

Changed​

  • The OptimizeDocument method of the PDF optimizer will now attempt to apply lossless compression for images with bitonal (Group4 or JBIG2 compression) and indexed (Flate or LZW compression) color spaces.

Version 1.4​

Added​

  • Before this update, only the common name (CN) of a signing certificate could be retrieved. With this update, you can get the full distinguished name (DN) of a signing certificate. The DN format is RFC 4514. The DN includes the legal name, country, and other information about the person or authority who owns the certificate.
  • Before this update, you could only read and write to file streams with the C API. As of this update, you can also use memory streams with the C API.

Version 1.3​

Added​

  • DocumentAssembler class. This class allows you to combine multiple input PDF documents into one output document, or split one input PDF document into multiple output documents.
  • You can now include a customizable signature appearance when Signing a PDF document. A signature's appearance may be any combination of text, images, and other PDF documents.
  • Linux: Added new distribution for older Linux systems (glibc 2.12+).

Changed​

  • Before version 1.3.3 you needed to use an evaluation license key to try the Pdftools SDK. With version 1.3.3, you can use the Pdftools SDK without a license key with watermarked output files. As a result, you can try the Pdftools SDK without any license key. To remove the watermark from the output files, contact the Pdftools sales team through the Contact page to get a full license.

Version 1.2​

  • Added the MetadataSettings class. This class allows you to set Metadata in the output PDF document, by providing them in the producer method's OutputOptions.

Changed​

  • Linux: The minimum required glibc version was upgraded from 2.27 to 2.34.

Version 1.1​

Added​

  • Signature validation for the digital signing functionality. This allows you to extract signing certificate information and trust chain information, and perform validation of time-stamps, handle expired certificates, use custom trust stores, and check for the latest document revision.

Changed​

  • Updated C API ZIP archive layout: The C API ZIP archive directory layout has been updated (see Getting-started).
  • Updated Java API ZIP archive layout: The Java API ZIP archive directory layout has been updated (see Getting-started).
