   OcrDocumentFontType fontType,
   String^ fontName

Parameters

languageName

The language name. See remarks for more information.

fontType

The type of font to replace.

fontName

The font name that will be used in final document.

You can also use GetFontNames and SetFontNames to get or set the font names using an array.

Use GetFontName and SetFontName to get/set the fonts used in the final recognized document (PDF, DOC, HTML, etc). The fonts will not be used when the final document format is text.

The OCR engine uses six different fonts when creating the final output document as follows: description:

The OcrCharacter.FontStyle member of each character returned in IOcrPage.GetRecognizedCharacters determines which font to use with the character. If the zone is ICR or MICR (the OcrZone.ZoneType member is OcrZoneType.Icr or OcrZoneType.Micrthen the character will use the ICR or MICR fonts accordingly.

The OCR engine keeps a list of fonts for some languages, for example all the Latin languages currently use the same font. So passing languageName equals to "en" for English or "de" for German will change the default Latin fonts used in the final document. This is the equivalent of passing null (Nothing in Visual Basic).

If the OCR engine supports Asian languages, then each language will have its own font sets and you can get/set these fonts individually. Currently, the LEADTOOLS OCR toolkits supports individual fonts for Latin (null), Japanese (ja), Korean (ko), Chinese (zh-Hans and zh-Hant) and Korean (ko). The following table lists the default fonts used for each language:

Note that changing the fonts is not recommended in most cases, the character position and size is calculated based on the default fonts even if the user changes the fonts before the recognition process. After the changing the fonts, it might be required to use IOcrPage.GetRecognizedCharacters and IOcrPage.SetRecognizedCharacters to further change the character position and font size to create the final output document.

For an example, refer to GetFontName.
