This function requires a native path. Use Path.FileMakerPathToNativePath to convert a FileMaker path to a native path if required. If you like to have the user choose the path, you can use FileDialog functions.
For Server be aware that server has limited permissions and may not be able to access all files on a computer.

Examples

Initialize with tessdata folder in same folder as database for english:

set variable $databasePath to Get(FilePath)
set variable $databasePath to MBS("Path.FileMakerPathToNativePath"; $databasePath)
set variable $databasePath to Substitute ( $databasePath ; ".fp7" ; ".fmp12")
set variable $databaseName to Get(FileName) & ".fmp12"
set variable $path to Substitute ( $databasePath ; $databaseName ; "" )
set variable $r to MBS( "OCR.Initialize"; $path; "eng")

Initialize on Server with tessdata in Server folder:

MBS( "OCR.Initialize"; "/Library/FileMaker Server/"; "eng")

Initialize on demand:

If [MBS("OCR.IsInitialized") ≠ 1]
Set Variable [$r; Value:MBS( "OCR.Initialize"; "/Library/FileMaker Server/"; "eng")]
End If
