TextTypeEnum (COM-based API)
TextTypeEnum enumeration constants are used to describe the type of recognized text.
enum TextTypeEnum {
TT_Normal = 1,
TT_Typewriter = 2,
TT_Matrix = 4,
TT_OCR_A = 8,
TT_OCR_B = 16,
TT_MICR_E13B = 32,
TT_Gothic = 64,
TT_Fax = 128
};
Elements
| Name | Description |
| TT_Normal | This value corresponds to common typographic text. |
| TT_Typewriter | This value tells Open API to presume that the text on the image was typed on a typewriter. |
| TT_Matrix | This value tells Open API to presume that the text on the image was printed by means of a dot-matrix printer. |
| TT_OCR_A |
This value corresponds to a monospaced font designed specifically for Optical Character Recognition. Largely used by banks, credit card companies and similar businesses. It may look as follows:
|
| TT_OCR_B |
This value corresponds to a font designed specifically for Optical Character Recognition. It may look as follows:
|
| TT_MICR_E13B |
This value corresponds to a special set of numeric characters printed with special magnetic inks. MICR (Magnetic Ink Character Recognition) characters are found in a variety of places, including personal checks. It may look as follows:
|
| TT_Gothic |
This value tells Open API to presume that the text on the image was printed in Gothic type. It may look as follows:
For this text type, Open API currently supports the following fonts: Textura (Gothic script), Fraktur and Schwabacher. |
| TT_Fax | This value tells Open API to presume that the text on the recognized image is produced by a fax machine. |
Note. If an image contains characters of a language and MICR characters, you must specify the MICR (E13B) text type and select the E13B language in addition to the main recognition language. You need not select the E13B language when recognizing English texts, because the English language already contains all E13B characters.
