Hi,

See: https://www.gdpicture.com/guides/gdpicture/v5/gdpictur ... DoOCR.html

You can specify the char list through the sCharWhiteList parameter.

IE:

Code: Select all

'Recognize only digits
OCR = Imaging1.OCRTesseractDoOCR(TesseractDictionaryEnglish, "c:\dicpath\", "0123456789"

'Recognize only alpha lowercase
OCR = Imaging1.OCRTesseractDoOCR(TesseractDictionaryEnglish, "c:\dicpath\", "abcdefghijklmnopqrstuvwxyz")

Best regards,

Loïc
