Are you sure the image returned from GetBinaryImage() is >= 24bit/
pixel?
(I'm newbie to Tesseract [and leptonica], but)
I think I read something somewhere that internally tesseract may be
using 8-bit/pixel images, and that may be what's being returned from
the GetBinaryImage() - the code you've presented appears to expect >=
24bit/pixel image...
