1.13 release notes

Before attempting to upgrade to Document Engine 1.13, make sure your application runs as expected on your current version. If you’re on version 1.6.1 or later, you can upgrade directly to 1.13. If you’re on an earlier version, follow the step-by-step upgrade path outlined in our upgrade guide.

Highlights

GdPicture

This release ships with GdPicture 14.3.20. The previous version (14.3.17) has now been replaced, and the changelog highlights many bug fixes, as well as many improvements.

Email-to-PDF conversion

Email-to-PDF conversion was improved, and it now renders a specific set of email headers (e.g. From:, To:, Subject:, and Date:).

OCR

This release enhances OCR capabilities with streamlined multi-language OCR support and expanded language coverage (120+ supported languages).

Previously, you could specify multiple language codes delimited by +, like so:

{
  "action": "ocr",
  "language": "eng+deu+fra"
}

You can now use a list of supported languages or their codes instead:

{
  "action": "ocr",
  "language": ["english", "german", "fra"]
}

You can specify languages using the following options:

  • Full language names (e.g. english, german) for commonly used languages
  • ISO 639-2 language codes (e.g. eng, deu) for all supported languages
  • Language codes with variants for specialized scripts — e.g. chi_sim_vert for Simplified Chinese vertical text, or deu_frak for German Fraktur

Newly available languages include:

  • Chinese (Simplified and Traditional)
  • Vertical variants for Chinese, Japanese, and Korean
  • Fraktur script support for Danish, German, and Slovak
  • Old variants of Italian, Georgian, and Spanish
  • Cyrillic variant for Azerbaijani and Uzbek
  • Latin variant for Serbian

See our OCR language support reference for the complete list of supported languages.

Document Engine 1.13 adds support for additional Office file formats: XLSM, XLSB, XLTM, XLAM (Excel macro-enabled formats), DOCM, DOTM (Word macro-enabled formats), PPTM, PPSM, POTM, and PPAM (PowerPoint macro-enabled formats).
