DWORD dwMask; Item Masks – SYM_MASK_FLAGS,MIN_LEN,MAX_LEN.
DWORD dwFlags; OR of valid flags for the given symbology.
DWORD dwMinLen; Minimum length for valid barcode string for this symbology.
DWORD dwMaxLen; Maximum length for valid barcode string for this symbology.
} SymFlagsRange_t, *PSymFlagsRange_t;
Structure for unusual OCR:
#define MAX_TEMPLATE_LEN 256
#define MAX_GROUP_H_LEN 256
#define MAX_GROUP_G_LEN 256
#define MAX_CHECK_CHAR_LEN 64
typedef struct _tagSymCodeOCR
{
DWORD dwStructSize; Set to size of ( SymCodeOcr_t );
DWORD dwMask; Item masks.
OCRMode_t ocrMode; OCR Enable/Mode structure.
OCRDirection_t ocrDirection; OCR direction structure. Not supported.
TCHAR tcTemplate[ MAX_TEMPLATE_LEN ]; Template for decoded data (‘d’ - decimal,
‘a’ - ASCII, ‘l’ - letter, ‘e’ - extended).
TCHAR tcGroupG[ MAX_GROUP_H_LEN ]; Group G character string.
