I want to know if there is possibility to define a LetterSet on ProcessImage Method for some language? (english for example)

Can the LetterSet improve recognition quality on "Invoice" document type?

Example of simple set: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z a b c d e f g h i j k l m n o p q r s t u v w x y z 0123456789 @#$%~" +-=/.,:;()!?

Thanks, Vitalie

The letterSet parameter is not supported for the full-page recognition (the processImage or processDocument methods). But you can use this parameter for the field-level recognition (the processTextField or processFields methods). In some cases when the fields can have only limited set of the characters, this parameter can be very useful.
