Version 4.1.0

Note: As of version 4.1.0 this wrapper will now match Tesseract's version to the first two numbers (Major.Minor) with the last number (Patch) reserved for changes in the wrapper. This is to avoid confusion with what version of tesseract is used. This does that semantic versioning is no longer used however breaking changes will be kept to the absolute minimum, even between major tesseract releases, and clearly denoted here if they are required.

  • Support for loading config files
  • Support for loading Pix from memory

Version 2.0.0

Note: Version 2 was initially going to introduce support for Tesseract 3.03 however as that hasn't been released yet and we have a few minor breaking changes due to Mono support which require a version increment (we use semantic versioning). Once the next version of tesseract is released we'll add it.

Breaking changes from 1.0

  • Tesseract.Interop is now internal which means we can make as many interop changes as we like as long as the public version doesn't change
  • TesseractEngine.Handle, Pix.Handle, and PixColormap.Handle are now internal
  • Logging is done to the Tesseract source, not Default.
