Glossary Item Box

Adds a new User dictionary item.

Declaration:

  Copy Code 
AT_ERRCOUNT ACCUAPI IG_REC_UD_item_add(
   LPCSTR pSection,
   LPCWSTR pUDitem,
   enumIGRecUDItemAttribute itemattrib
);

Arguments:

pSection Name of the section where the word should be added. If the specified section does not exist, a new section will be created automatically.
pUDitem Pointer to a UNICODE string containing the item to be added.
itemattrib Attribute for the UDitem to be added. See enumIGRecUDItemAttribute for possible values.

Return Value:

Returns the number of ImageGear errors that occurred during this function call.

Supported Raster Image Formats:

This function does not process image pixels.

Remarks:

The function appends a new User dictionary item (or simply UDitem), that is a literal or a regular expression, to the User dictionary currently opened for editing by the IG_REC_UD_edit_open function. The item will be added to the pSection of the User dictionary.

  1. User dictionary items are UNICODE strings, and they must be no longer than AM_MAX_UD_ITEM_LEN characters (including the terminating zero). They may contain spaces and punctuation characters.
  2. When adding a new UDitem, its itemattrib also has to be specified. An item can be added either as a literal or as a regular expression. UDitems having the regular expression attribute will be evaluated for conformance during the checking of the recognized result.
  3. When the characters to be added are contained in the Windows ANSI (1252) Code Page, the easiest way to define the pUDitem string is with a wide-character-string literal, L"characters". If any needed character falls outside the ANSI (1252) Code Page, you can convert these characters one after each other with the IG_REC_util_codepage_to_unicode utility function, which converts a single character code from the current single-byte Code Page value (IG_REC_output_codepage_set) to its UNICODE representation.

Maximal length of the dictionary item is AM_MAX_UD_ITEM_LEN.

Example:

  Copy Code 
AT_ERRCOUNT ErrCount = 0;
ErrCount += IG_REC_UD_set(NULL, NULL);
ErrCount += IG_REC_UD_edit_open();

ErrCount += IG_REC_UD_item_add("LiteralSection", L"Heereswaffenamt", IG_REC_UD_ITEM_ATTR_LITERAL_STRING);
ErrCount += IG_REC_UD_item_add("RegexpSection", L"[A-Z]", IG_REC_UD_ITEM_ATTR_REGULAR_EXPRESSION);

ErrCount += IG_REC_UD_edit_close();
