Data Types

Data type names have been modified according to the following tables. Note that the structure fields and enumeration item names must be corrected as well according to the new recognition header files. In most cases, new names can be easily matched to the old ones.

AT_REC_LETTER

This structure has been modified significantly. The following table maps the members of ImageGear v16.1 LETTER structure to v17 (or later) AT_REC_LETTER structure.

IG16.1 LETTER	IG17 (or later) AT_REC_LETTER	Description
WORD left WORD top WORD width WORD height	AT_RECTANGLE Rect	Same meaning, but different representation.
short base	AT_WORD Baseline	In IG16.1, base used to be a top-relative value referencing the rectangle of letter. In IG17.0, BaseLine uses absolute coordinates.
BYTE space BYTE spaceErr	AT_WORD SpacesCount; enumIGRecSpaceType SpaceType;	In 16.1 'space' field signals whether there are space(s) in front of the recognized code character. In IG17.0 space is a regular character with some additional information, such as type of the space (can be space, tab, bullet, leader tot, leader line, leader hyphen) and number of spaces. Space in IG16.1 had its own confidence info. In IG17.0 the confidence is common for spaces and non-spaces.
WCHAR code	AT_WCHAR Code	Same meaning.
WCHAR code2 WCHAR code3	AT_BYTE AlternativeCodesCount AT_DWORD AlternativeCodeOffset	In IG16.1 two alternative choices for the character are possible, which are placed to code2 and code3 directly. In IG17.0 there is a choice count and an offset of the choices in the external choice array.
	AT_BYTE WordSuggestionsCount AT_DWORD WordSuggestionOffset	New fields that allow getting word suggestions for the whole word.
WORD zone	AT_WORD ZoneIndex	Same meaning.
WORD cellNum		The field was undocumented in 16.1. It has been removed in 17.0.
DWORD history		Removed.
BYTE boldness		Removed; see FontAttribute.
BYTE info	enumIGRecLetterExtraInfo ExtraInfo	The field was undocumented in 16.1. It has been removed in 17.0.
BYTE err	AT_BYTE Confidence AT_BOOL WordUncertain	In IG16.1 the field combines two values. In IG17.0 the values are separated.
BYTE font	enumIGRecFontType FontAttribute;	Same meaning.
BYTE fontSize	AT_WORD CapitalLetterHeight	New field expresses a measure of the capital letter height in pixels.
BYTE makeup	enumIGRecMakeupInfo Makeup	Same meaning; more info is available in the new field.
short lang; short lang2	enumIGRecLanguages Language enumIGRecLanguages AlternativeLanguage	Same meaning.
	AT_BYTE UnderlineDotWidth	New field in IG17.0.
	AT_BYTE UnderlineGapWidth	New field in IG17.0.
	AT_BYTE ForegroundColorIndex	New field in IG17.0.
	AT_BYTE BackgroundColorIndex	New field in IG17.0.
