TOCR V3 comes in two editions - Standard (SE) and Professional (Pro). The Pro edition is the successor for developers and integrators previously using V1.4 and V2.0. SE is for customers who don't intend to develop the software further.
Licences for SE are not compatible with Pro.

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)

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• Because licences are additive the TOCRGetLicenceInfo routine has been superseded by TOCRGetLicenceInfoEx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

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

• There have been a number of minor bug fixes to the engine.
• A new facility has been added to allow "exact" position reporting of characters found on a page.

Viewer program changes

• The new features in the viewer program are a batch processing facility and the ability to copy either the image or the results to the clipboard.
