Spell checking uses third-party language-specific spell checkers. There are two kinds of spell checkers:

• Language dictionaries ("language checking")
• Vertical dictionaries ("vertical language checking")

The Capture SDK is delivered with twenty one different Language dictionaries (English, German, Dutch, Polish, Russian, etc.). These are generic language dictionaries; they contain between 100,000 and 200,000 entries.

Vertical dictionaries apply to special professions, and in the toolkit they can be treated as extensions to the Language dictionaries, though they can even be used when no Language dictionary is specified.

The Capture SDK is delivered with 9 different Vertical dictionaries for three professions (financial, medical, and legal) in four languages (English, German, French, and Dutch).

Specifying the Spelling language (Language dictionary) and/or a Vertical dictionary is page-level setting. Once a Language dictionary has been specified, the language checking will be applied to all zones on the page, unless their IG_REC_ZCF_LANGDICT_PROHIBIT flag is set.

Similarly, once a Vertical dictionary has been specified, the vertical language checking will be applied to all zones on the page, unless their IG_REC_ZCF_VERTDICT_PROHIBIT flag is set.

Available vertical dictionaries can be enquired using IG_REC_vertical_dict_available_count_get(), IG_REC_vertical_dict_available_desc_len_get(), and IG_REC_vertical_dict_available_desc_get() functions.

AT_ERRCOUNT nErrCount;
char legaldut[] = "Dutch Legal Dictionary";
nErrCount = IG_REC_spelling_language_set(IG_REC_LANG_DUT);
nErrCount = IG_REC_vertical_dict_enable(legaldut);
