Requires MBS PlugIn AND the 'tessdata' resources.
Put 'tessdata' folder into FM Extensions folder OR change the value for '$path = ' to your liking according to MBS path definitions.

tessdata resources is part of the MBS PlugIn download:
… / MBSFMPlugin820 / Examples / OCR / tessdata

The cf also works on Server via PSoS:
- put 'tessdata' folder into FMServer Extensions folder
- create new cf "MBS_OCR_PSoS"
- change $path to
$path = MBS ("Path.FilemakerPathToNativePath"; "/Library/FileMaker Server/Database Server/Extensions/") ;
