Name

Description

TT\_Gothic

This value tells ABBYY FineReader Engine to presume that the text on the recognized image is printed with the Gothic type. It may look as follows:

Fraktur

TT\_Handwritten

This value corresponds to handwritten and handprinted text. For example:

Handwritten

handwritten

Handprint

handprinted

TT\_Index

This constant corresponds to a special set of characters including only digits written in ZIP-code style. They look as follows:

Index_LetterSet

TT\_Matrix

This value tells ABBYY FineReader Engine to presume that the text on the recognized image is printed on a dot-matrix printer. It may look as follows:

page_frag_matrix

TT\_MICR\_CMC7

This value corresponds to a special set of characters, which includes only digits and A, B, C, D, E characters, written in MICR barcode font (CMC-7). MICR (Magnetic Ink Character Recognition) characters can only be recognized for the Latin languages and may look as follows:

cmc7

TT\_MICR\_E13B

This value corresponds to a special set of characters including only digits and A, B, C, D characters printed in magnetic ink. MICR characters are found in a variety of places, including personal checks. However, they can only be recognized for the Latin languages and may look as follows:

MICR-E13B

TT\_Normal

This value corresponds to a common typographic type of text.

TT\_OCR\_A

This value corresponds to a monospaced font, designed for Optical Character Recognition. Largely used by banks, credit card companies and similar businesses. It may look as follows:

OCR-A

TT\_OCR\_B

This value corresponds to a font designed for Optical Character Recognition. It may look as follows:

OCR-B

TT\_Receipt

This value corresponds to a text of a receipt. This type of text is designed for recognizing sales receipts, invoices, etc. Unlike the other types, it is not concerned with the actual font of the text. Rather, it tells the recognizer that there may be text of low quality, mostly in monospaced or normal font. The typical receipt text can look like this:

receipt_text

TT\_Typewriter

This value tells ABBYY FineReader Engine to presume that the text on the recognized image is typed on a typewriter. It may look as follows:

page_frag_typewrite
