Version Comparison

Latest version - What's new? - What's different?

The latest version of the OCR engine is 3.3 (TOCR V3.3)

Version 3.0 to 3.3 changes

OCR engine changes

  • More accurate and stable than V3.0
  • There have been a number of additonal bug fixes to the engine from V3.0 to V3.2

  • A free upgrade is available to all users of the V3.0 and V3.2 Professional Edition
  • V3.0 Standard Edition has been discontinued

Viewer program changes

  • TOCR now includes speed switches allowing for faster recognition if needed. Faster recognition leads to some loss in accuracy
  • Additional lex features have been added and auto-lex is now an option, allowing TOCR to automatically decide whether to use the lexicon function for a given image
Version 2.0 to 3.0 changes

OCR engine changes

  • More accurate and stable than V2.0
  • Simple TWAIN compatible interface added
  • Images with missing or zero DPI can now be recognised
  • The maximum image size is now 12,000 pixels in X and Y
  • All errors can be logged to a file, making installing TOCR as a Windows Service easier
  • You can now set the OCR engine priorities
  • Two new functions added: TOCRSetConfig and TOCRGetConfig. These allow you to change the service error mode and priority dynamically
  • A flag has been added to process OCRB better (at the expense of accuracy with other fonts)

Viewer program changes

  • Moving through multi page files is easier (you can enter the page number or use the Up, Down, PageUp, PageDown, Home and End keys)
  • The zoom on multi page files can be set individually or locked for all pages
  • The wheel mouse now works in the image pane
  • Focus bars added and there is a new menu to show/hide the toolbar/focus bars and status bar
  • Image can now be flipped horizontally, vertically and rotated through 180 degrees
  • Image editing has been improved - the position and sizing of the selection rectangle is better and the selection and image can be copied/pasted/saved
  • A formfeed character can now be added to batch output separators (%x)
Version 1.4 to 2.0 changes

OCR engine changes

  • The engine recognises the Euro symbol and accented characters (version 2 characters). (This depends on the licence you have installed. If you have a standard licence installed then you will get a 100 A4 page trial of the higher characters, after which the OCR engine will revert to recognising only the version 1 characters)
  • Licences are additive. If you purchase two or more licences you can run two or more OCR engines in parallel
  • Lex processing now supports, in addition to English: Danish, Dutch, Finnish, French, German, Italian, Norwegian, Portuguese, Spanish, Swedish without the need to specify the language in advance
  • Because licences are additive the TOCRGetLicenceInfo routine has been superseded by TOCRGetLicenceInfoEx
  • The engine is more accurate and stable. Accuracy when Lex processing is turned off has been greatly enhanced

Viewer program changes

  • Text results can be positioned to reflect the image
  • The viewer program should now work on multibyte machines
Version 1.3 to 1.4 changes

OCR engine changes

  • Two new functions have been added. TOCRGetResultsEx returns extended information on results. TOCRConvertFormat supersedes TOCRConvertTIFFtoDIB and can return a memory mapped file
  • A minimum of 25 DPI has been introduced to avoid using up all the 100 A4 limit in one go when a file with badly set resolutions is OCR'd
  • Engine is now more stable and has been re-optimised to increase accuracy

Viewer program changes

  • Changed to use TOCRConvertFormat to avoid using temporary file
  • Batch processing options have been enhanced and are now saved in the registry
  • The results window pane is now a textbox to allow editing
  • There are extra buttons on the Processing options page to make disabling characters easier
  • The ability to change the image DPI has been added

OCR engine changes
